Weatherford is proving the value of multilaterals in the field. Our practical, safeand cost-effective technology shifts their value in your favor.
Project SummaryWeatherford successfully installed a StarBurst™ multilateral system for BP atWytch Farm on Furzey Island. The StarBurst system was set at 2,370 metersand created a level 4-cemented junction for structural integrity. The installationof the 9%" x 7" system, without operational or functional problems, resultedin completion ahead of schedule. Designed functionality of the junction allowedthe 1,200-meter lateral to be drilled and completed quickly and safely. The parentbore was then reopened by a simple but accurately designed series of perforationsto the face of the hollow whipstock without damage to the casing.

Who Is
By Christine McGeeEditor, W Magazine
It depends whom you ask. Peoplewho have worked in this industryfor decades often associateWeatherford with its classic busi-ness lines of tubular running,
cementing, fishing and rental. Some of our larger, multina-tional clients associate us more with our emerging tech-nologies - underbalanced systems, expandable technology,drilling with casing and production optimization. Andothers simply connect us with providing one specificproduct or service.
The truth about all these perceptions is that each ofthem is correct, but too limiting in scope. Weatherford isan amalgam of all these descriptions because we offer oneof the industry's most diverse portfolios of products andservices for drilling, intervention, completion and produc-tion applications.
At the same time, there are hallmarks of theWeatherford brand thattranscend specific prod-ucts, services and capabil-ities. These are thoseintangible qualities ofpragmatism, responsive-ness and effectiveness -qualities that all add upto making our clients'reservoir recovery opera-tions more productive.
To better reflectthese diversities and simi-larities withinWeatherford'sofferings, we havechanged the formatof W Magazine so youcan get a more completepicture of Weatherford's
breadth and depth. These changes include:• Technology Transfer, a section that highlights our
latest global technology commercializations;• Real Results, which focuses on three case historiesusing some of our newer products or services;
• Bundled Strategies, which highlights specific ways weare bringing products and services together to bettermeet customer needs; and
• Enterprise Excellence in Action, whichdemonstrates our renewed commitment to aculture of excellence.
We've also added some columns that help demonstrateWeatherford's long-standing reputation for service - A Dayin the Life, which focuses on a Weatherford employee andthe value he or she adds to the company, our heritage inclassic market segments (Flashback), and the evolution ofparticular product lines [Product Line Focus).
We hope you find this new format useful. Moreimportantly, we hope some of the articles will broadenyour current perception about who Weatherford is andwhat we stand for. f

Demonstrating the
By Stuart Ferguson, ChiefTechnology Officer, Weatherford
We live in an industry climatethat currently focuses on quarter-to-quarter performance. For ourclients, this means consistentlydelivering on their production tar-
gets. For Weatherford, in part, this means rapid com-mercialization of new technology.
In aligning ourselves with our clients' needs, we haveconcentrated on developing production-enabling tech-nologies - those that convert reserves into revenue. Inmost cases, our new products either drive down wellcosts, which lowers the threshold to bring on reserves,or increase well productivity, which accelerates produc-tion and cash flow. In the best cases, we can achieveboth of these ends.
However, as we all know, developing the technologyis only part of the equation. To make it pay off for bothour clients' reservoirs and for our own investment, wemust widely deploy new technology in the field, whichis where we often face our greatest challenge.
There are several factors playing into this dynamic.For starters, time pressure and a risk-averse environ-ment within many exploration and production compa-nies often leads to maintaining the status quo. Peopleare under enough pressure to meet production targets,they don't want to add the variable of "unproven tech-nology" to the mix.
Secondly, the oil field service sector in general hasn'tdone a stellar job in demonstrating a new technology'svalue proposition. We have tended to emphasize fea-tures rather than benefits, and generalities rather thanspecifics.
This latter point brings us to the purpose ofTechnology Transfer, a newly created section in WMagazine that follows this column. The articles inTechnology Transfer highlight some of our most prom-ising technologies and, true to our reformed words,
includes information about the value the technology canadd to the reservoir, how it is being applied in specificapplications and the results of those applications.
The technologies featured in this edition include:• the SURE Process, which can greatly enhance the
ability to value accurately underbalanced drilling(UBD) vs. conventional drilling for a particularreservoir or group of reservoirs. For instance, SUREallows operators to quickly and inexpensively screen100 reservoirs, narrow the field to 10 likely UBDcandidates, and then quantify the likely value rangethat UBD will realize. Under traditional circum-stances, the outcome of SURE could not beachieved without drilling and analyzing a very largenumber of analog wells - an extremely expensiveroute;
• the TrendSET™ EM/MWD system, a flexible meas-urement-while-drilling [MWD) system that meetsthe challenge of both underbalanced and conven-tional applications using two means of data trans-mission: electromagnetic and mud-pulse telemetry.In field trials, the electromagnetic system transmit-ted information from almost 11,000 ft C3,355 m), fardeeper than any similar tool in this type of applica-tion; and
• Clarion Optical In-Well Seismic Sensing System,which uses seismic technology to improve produc-tion, rather than exploration, of hydrocarbons. In afield trial last year, the Clarion system demonstratedthat a distributed array of fiber optic sensors couldreadily be deployed on a production tubing stringand produce high quality reservoir images.
I hope you find this information valuable. ^

SURE UBSelectionEvery operator wants to improve productivity and maxi-mize net present value, from his or her assets or potentialacquisitions. Underbcuanced drilling has always been anoption for meeting that goal, but previously has been seenas expensive and unquantifiable,
Weatherford's new Suitability for Underbalanced ReservoirEvaluation (SURE) process and novel evaluation software,introduced in late January, can greatly enhance the ability toaccurately value underbalanced drilling (UBD) vs. overbal-anced drilling for a particular reservoir.
The core of the SURE process is the Reservoir ScreeningTool (RST)™, a quick-look screening software, and theReservoir &f Damage Assessment (RDA)™ software.Weatherford developed this software in conjunction with top
4 Phases of SURE

consultants in formation damage analysis (Hy-Cal), riskanalysis and sub-surface disciplines.
Greg Chitty, director of reservoir suitability analysis forWeatherford, compares the process to the justification ofimplementing fracturing technology for productivityenhancement in the early days of fracturing. "Hydraulic frac-turing makes production of tight gas economic, but it isn't acure-all. Fracturing shouldn't be used on all reservoirs or inall situations, and operators pumped a lot of money down alot of wells before the industry developed the process thatallowed those operators to quantify the economic and tech-nical results they were achieving with fracturing technology,"he said.
The SURE process applies a similar reasoning to the justi-fication of implementing UBD in a given reservoir. Under-
balanced drilling is not an economic solution forevery reservoir. The SURE process allows opera-tors to quantify the results they can expect fromUBD so that accurate performance comparisonscan be made between underbalanced (UB) andoverbalanced technology. And it will do the jobquickly at a fraction of the cost in a fraction of thetime of expensive engineering studies.

RESULTS
The four phases of SURE begin with identifying a reservoir candidateand end with presenting the results of data gathering and analysis.
How the Screening WorksIn a typical situation, the operator will ask theWeatherford Reservoir Suitability Analysis Team(RSAT) to analyze and evaluate its assets for UBdrilling. The first step the team will take is toscreen the asset[s) using the RST. This portion ofthe analysis is quick, inexpensive and requires only15 descriptive reservoir parameters as input. Thescreening tool will then calculate geologic,damageability and treatability indices to yield ascore from -100 (worst) to 100 (best), with 0 beingbreakeven. If the reservoir scores more than 70, itis suggested to implement UB drilling. If the reser-voir is between -20 and 69, an RDA study is rec-
ommended. If the candidate scores below -20,it is likely not a viable candidate.

technology transfer
In the second step, the RDA software can provide a
more detailed analysis that will ultimately yield pro-
ductivity and net present value (NPV) comparisons of
overbalanced drilled and completed wells vs. UB drilled
and completed wells.
In the final step, the RDA software employs a Monte
Carlo simulator to risk input properties of drilling, comple-
tion, formation damage and reservoir characteristics to
obtain a statistical distribution of skin damage and a forecast
of costs, production and NPV of drilling and completion
alternatives.
"It gives operators a novel vehicle to enhance confidence
in making the UB decision," Chitty said.
ШЯШНИИНВИНЕВШНВНВН8ШAdvantages of SUREUsed properly, the SURE process helps the operator:
• find the most likely UB candidates;
• understand the factors that will differentiate UB from
overbalanced;
• manage uncertainty and risk; and
• improve predictability of UB results.
Example: If an operator gives the team 100 reservoirs to
analyze, the RST analysis might eliminate 75 reservoirs as
poor candidates. Further scrutiny could narrow the field to
five clear winners that would be excellent candidates and are
ready to drill Then there may be as many as 15 mediocre
scoring candidates that would require an RDA in-depth study
to prove candidacy. The SURE process now has allowed the
operator to quickly and inexpensively look at 100 reservoirs
and in effect has lowered the UBD "opportunity finding cost"
ResultsThe SURE process will not guarantee a successful horizon-
tal UB well, but it will help manage the risk involved. For
instance, in a given field, an operator might have drilled 100
wells with overbalanced drilling and had a consistent $4 mil-
lion NPV on those wells.
But what happens when the field is depleting and the
operator's NPV of the overbalanced drilling program is
shrinking? The RST software might tell that operator the
reservoir is a good candidate for UB. Upon further analysis,
the RDA may predict a 70% chance of UB yielding an NPV
of greater than $4 million and a 10% chance of yielding an
NPV of $6 million. In this case, UB will give the operator a
chance to greatly improve financial performance beyond the
limits of what overbalanced drilling could achieve.
In summary, the operator can continue to drill wells the
traditional way and idly watch the NPV dwindle, or he or
she can assess the risk/reward scenario of UB to try and
obtain higher returns.
A more obvious UB prospect might be depleted reser-
voirs or where drilling related damage is suspected. For
example, operators may be pleased with a skin of -2 as esti-
mated by transient analysis of a horizontal well and think
the well is a peak performer. However, traditional transient
analysis will not account for permeability heterogeneity in
the reservoir, which can lead to misinterpretation.
The SURE process gives operators a different perspective
for interpretation. A proper post-well analysis of damage
performed by RDA software will show that for the horizon-
tal well, the actual skin may be closer to 4. Both RDA and
transient skin values will give the operator the same produc-
tion, but the RDA-calculated skin challenges the transient
analysis perception that there was minimal drilling and com-
pletion skin. This should show the operator that there is
clearly an opportunity to improve performance in a well that
was thought to have an excellent completion. ^,_

Versatile MWD MergesBrain with BrawnWeatherford has developed a reliable, durable, modularmeastirement-whilerdnlling system 'that can meet the chal-lenge of harsh drilling conditions in underbalanced environ-ments or the more basic requirements of overbalancedapplications.
In the electromagnetic measurement-while-drilling(EM/MWD) world, non-productive time usually stems fromusing systems that aren't reliable.
With this in mind, Weatherford set out to develop anEM/MWD system that provides a magnitude improvementin reliability. The result is TrendSET™, an EM/MWD systemthe company currently is field-testing and will have commer-cially available in the first quarter of 2004.
The TrendSET system signifies a move from conven-tional systems retrofitted to work in extreme environmentsto a tool designed from the ground up specifically for thatpurpose.
"We feel strongly that our ability to grow as a directionaldrilling company is going to require a proprietary MWDsystem that is differentiated in one way or another fromthe competition," said Chip Swarr, product line managerfor Drilling Systems. 'This is a new-generation MWD sys-tem, and it's probably the only one out there. There aredozens of existing systems, but nobody else has startedwith a clean sheet of paper and created a new one.
"We've run the other guys' systems, and in some cases, it'scost us work by making the project cost-prohibitive."
UB Applications: The End GameProviding a reliable system that could work withWeatherford's other underbalanced CUB] offerings was akey business driver in initially developing the technology.For starters, the underbalanced drilling environment isharsh, characterized by the extreme shock and vibration ofthe technique. As a result, TrendSET's electronics werespecifically designed to withstand these conditions.
Another requirement was developing a system thatcould transmit signals through compressible fluids sinceconventional mudpulse systems used for MWD have been

limited in their ability to perform this function. TrendSETsolves this problem because it has two means of data trans-mission: E-WAVE™ electromagnetic data transmission andDuraPulse™ mud-pulse telemetry. E-WAVE serves as thewireless guidance for the UB system, transmitting direc-tional information and formation evaluation data fromdownhole.
Mix and Match FlexibilityThe beauty of TrendSET, however, is that it's not just for UBapplications. The system contains the full complement of
8 I W Magazine I 2004 First Quarter
technology transfer
MWD sensors, including directional, pressure, gamma and
resistivity, and allows its components to be combined for the
precise application needed.
For instance, it's ideal in conventional applications, pro-
viding higher reliability and faster data rates than conven-
tional MWD tools. With no moving parts, the sub is more
reliable than a mudpulser, so more time is spent on the
bottom drilling instead of tripping for pulser failures. The
telemetry also allows for higher data rates than a pulser-
based MWD system, so less time is spent waiting on sur-
veys, tool faces or data.
Additionally, the surface detection software can recognize
and filter signals a magnitude smaller than competitive sys-
tems, allowing for greater depth capability. The tool will
work in areas above highly resistive formations, anhydrates
or salt zones.
Real Results — North AmericaSo far, several of the tool's components have been tested
extensively in shallow gas wells in southern Alberta, Canada,
and more recently it's been applied in deeper directional
wells in the mid-continent. The result has been more than
500 hours of testing with no significant tool failures.
A more integrated version was tested recently by Tom
Brown Inc in the ACU field in Terrell County, Texas.
Missing only the custom-designed probe and the surface sys-
tem software, the test was primarily designed to evaluate the
depth limitations of the E-WAVE transmission system.
The system features high data transfer rates and can
measure annulus and bore pressures at the bottomhole
assembly to verify UB conditions. It's temperature-rated to
304T (150°C) and more for use in harsh environments. Its
greater signal resolution allows for greater depth capability.
In addition to UB conditions, the tool is well suited for
harsh drilling environments requiring fast reliable data
transfer and for difficult lithologies.
"We were looking at the transmission characterization,
and we've achieved our goals in that area," Swarr said. "In
fact, in my opinion, we've over-achieved them."
Swarr said that in addition to testing depth limitations,
the transmission system also was challenged by being in a
vertical hole where there's not always wall contact and trans-
mitting through oil-based mud.
"We were successful with all three of these goals," he said.
Brian Franks, a drilling and completions engineer for
Tom Brown, added that the test was more beneficial to his
company than originally anticipated.
'It enabled us to survey more quickly and get help to
determine our well location faster than a single-shot survey
method would have," Franks said. 'The time savings was the
best benefit"
Additionally, using TrendSET compared favorably to a
traditional MWD survey.
"That's a lot more expensive, and it requires actual circula-
tion," he said. "We were able to survey more quickly than
with MWD, and the results were comparable."
In fact, the companies had the opportunity to compare
the accuracy of TrendSET data with single-shot data and
found it to be comparable.
Most impressively, Franks estimated the tool was trans-
mitting information at about 10,800 ft (3,294 m).

Clarion™ System Makes SeismicMore "P" Than "E"Seismic techniques traditionally Imve been used to explore,rather than efficiently produce, hydrocarbons. The followingarticle explains how Clarion, an optical, permanent in-wedseismic sensing system, is changing that standard.
The Evolution of Seismic TechnologySince the late 1970s, the industry has recognized the poten-tial of in-well seismic methods to improve exploration suc-cess, reduce drilling costs, control uncertainties and improveproductivity. Specifically, borehole seismic technology hadbeen earmarked as a natural link to further integrate surfaceseismic, core data and well logs. The geophysical informa-tion extracted from periodic borehole seismic surveys
Clarion delivers a high-quality seismic data stream through optical seismic sensing sta-tions, which are connected together and at the surface through rugged optical cable.
acquired with wireline deployed equipment, however, wasnot limited. Furthermore, sensor technology was not reliableenough and acquisition too costly for long-term imagingand monitoring applications.
"The market was ready for a simple, cost-effective and reli-able dynamic production optimization and reservoir man-agement capability," said Tad Bostick, vice president of busi-ness development for Weatherford's Intelligent Completionbusiness unit "Our answer was Clarion, an optical seismicsensing system that is installed during the completion phaseand remains in place in the wellbore throughout the life ofthe well. Its purpose is to deliver reliable, high resolution on-demand reservoir imaging that contributes to increases in
recovery and acceleration ofproduction."
Bostick also noted that tomeet the market need,Weatherford found a way tofast-track its "answer":Clarion's proof-of-conceptthrough product launch atthe 2003 Society ofExploration Geophysicistsconvention was less thanfour year's old.
"The whole progressionwas, first, to demonstratethat we could actually makeuseful multicomponent seis-mic measurements with anoptical system," Bostick said."That was achieved at theend of 1999 and into 2000.After that, we worked onsmaller, deployable, fit-for-purpose sensors, along witha state-of-the-art opticalmulti-channel architecture.This allowed us to imple-ment reliable seismic arrays
10 I W Magazine I 20O4 First Quarter
technology transfer
for long-term deployment within the tight constraintsfound in wellbores.
'The next step has been to integrate the seismic array intothe wide variety of completion designs and to install the sys-tems into production -wells. What remains is to validate themeasurement capabilities in the various reservoir environ-ments found throughout the world, implement the manage-ment and processing of data acquired from repeated imag-ing surveys and continuous monitoring, and combine theseismic data with other permanently monitored data toimprove the production and recovery processes."
Clarion's Benefits: Clear + NowThe Clarion system enables production optimization by mak-ing high-resolution [Clear) on-demand [Now) reservoir imag-ing possible. This facilitates the optimal placement of devel-opment and infill wells, reduces drilling and completioncosts, improves remedial action planning and implementa-tion to manage water and gas ingress, and advances theunderstanding of reservoir sweep and voidage replacement
Clarion also shifts the exploration and production (E^P)seismic game to more "P" than "E" by providing better linkagebetween the micro and macro investigative scale and betterintegration of an operator's multi-disciplinary competencies.
For instance, in the case of micro and macro investigativescale, production and reservoir management disciplineswork on different scales ranging from the microscopic scaleof the petrophysicist to the macroscopic scale of the geo-physicist Likewise, investigative data acquisition techniquesoperate at different scales. Coring investigates to a micro-scopic level A surface seismic survey investigates at a scale ofhundreds of meters to many kilometers. Only by merginginvestigative data and analysis at different scales from differ-ent disciplines can a comprehensive image of the producingreservoir asset be acquired. Weatherford's Clarion systemenables this link.
In the case of integrating an operator's multi-disciplinarycompetencies, an ongoing hurdle for any production time-lapse application is the gap between the geophysical com-munity and the engineering community.
"The geophysical community is concerned with sensors,

data acquisition, images and attributes. The completionengineers are concerned about how we're going to getthings in the wells, while being sure they're safe and effi-cient and don't add any significant risk to the well. Thenthere are the reservoir and production engineers, the oneswho will ultimately benefit from the seismic informationbeing folded back into their domain," Bostick said.
Weatherford's offering of an integrated service bringsthese different disciplines together.
"If you're talking about seismic production optimization,you have to get all the parties involved. Geophysicists can'tdo it independently. None of them can."
Two other benefits include permanent installation anddecreased uncertainty. Clarion is permanently installed,which removes the risk to well integrity and the lost pro-duction and cost associated with intervention-based bore-hole seismic techniques.
Clarion's sensors decrease uncertainty by providingconsistent, unchanging reference points in terms of depthand performance. They don't move or degrade during time.In 4-D applications, they eliminate repeatability uncertain-ties that can frequently result from repeat deployment oftemporary in-well sensors. From one survey to the next, thesensors eliminate data incompatibility and errors caused byusing different sensor types with different performancesourced from different contractors.

Field Trial ResultsWeatherford conducted a series of field trials as part ofClarion's development plan to incrementally prove the var-ious aspects of the system. The first trial focused ondeploying a single multicomponent sensor downhole,with the primary goals of coupling the sensors to the for-mation, examining signal-to-noise ratios and gauging theperformance of the optical sensors relative to referencevertical seismic profiling (VSP} tool measurements.Results of the study indicated multicomponent seismicdata could successfully be acquired with tubing-deployedoptical sensors.

Two types of permanentseismic surveys are being conducted in the field, VSP andextended microseismic monitoring. Previously completedfeasibility studies using conventional wireline tools havedemonstrated the ability to map the gas-water contactusing VSP and potentially correlate microseismic events togas injection and production activity.

The sensor output was interfaced in analog form to aconventional seismic recording system. Comparisons weremade to field data previously acquired with wireline VSP,and a good correlation was found.
While the initial acquisition went smoothly and thedata showed good repeatability, results of the time-lapsestudy conducted later were pending at press time. But theinstallation demonstrated that a distributed array of fiber-optic sensors could be readily deployed on productiontubing in a cased hole with minimal impact to the well.The next stage is to move into a more sophisticated multi-station installation offshore.
Clarion Goes CommercialMoving forward, Clarion is in full commercialization phase.
"We've reached a high level of confidence with theIzaute installation. Our focus now is working on gettingthe product and the manufacturing facilities ready to goalong with training the field operations and marketingstaff."
Bostick said Weatherford also is cross-training peopleacross the intelligent completions business unit on inte-grating Clarion with other permanent optical sensing prod-ucts such as temperature, pressure, flow and phase frac-tion, as well as with in-well flow controls.

One of Weatherford's key strategies since the late 1990s
has been to better leverage its global footprint through
superior in-country expertise. The following real result
details how the company's executing this strategy in
Southeast Asia.
SituationWeatherford has been working for years in Indonesia
through an alliance with its agent P.T. Catur Khita Persada
to establish in-country core expertise. In one project under
that arrangement, Indonesian Gatut Widianoko of
Weatherford began working with BP Indonesia on three
large fields - Bima, Ardjuna and Arimbi - off Java's
north coast to optimize gas lift operation and improve pro-
duction, which he was able to accomplish on a handful of
test wells. As a result, Weatherford was awarded an opti-
mization contract to analyze and rework gas lift systems on
190 wells in the fields.
SolutionThe optimization process was broken into five key objectives:
• field review of surface piping and restrictions to
reduce any surface bottlenecks;
• field training of BP operations personnel in proper
operation, testing and troubleshooting techniques for
gas lift wells;
• training of gas lift shop personnel to address proper
valve calibration, preparation and repair;
• technical review of all well data including well tests,
well history and current gas lift settings; and
• improve field installation procedures.

Gatut began implementing these objectives throughout the
Java field. One complicating factor in the Java gas lift instal-
lations, however, was the high concentration of dual-gas lift
wells, which are notorious for problematic operation and
difficult to optimize.
To solve the problem, Gatut initiated a simplified tech-
nique called "casing-head tuning," a straightforward process
that involved the following steps:
1. The team members drew graphs of the well
conditions, including the static and flowing pressure
gradients.
2. From available information, they then performed an
engineering analysis to determine the optimal kick off
and operating pressure. Typically, the operating pres-
sure would be chosen at 90% of kick-off pressure.
A diagram cutaway shows the downhole Weatherfordvalve that allows technicians to tailor casing-headpressure for optimum performance.

3. Once the valve string was correct, the technician
would inject gas at various rates, monitor the corre-
sponding casing-head pressure, determine the opti-
mum gas lifted production and log the corresponding
casing-head pressure.
4. The field personnel would then monitor and main-
tain this casing-head pressure to maintain optimal
well production.
ResultsThe casing-head tuning simplified the field operations and
provided adequate criteria to maintain and hold improved
performance from gas lifted wells.
One well, for example, was producing 216 b/d of oil and
864 b/d of fluids with a casing-head pressure of 200 psi
before adjustments began. After raising pressure to 300 psi,
the well produced 225 b/d of oil in 898 b/d of fluids.
Increasing the pressure to 400 psi increased production to
231 b/d of oil with 924 b/d of fluids.
A pressure setting of 440 psi gave the team 288 b/d of
oil in 1,152 b/d of fluids. Another boost in pressure to 480
psi yielded 252 b/d of oil and 1,008 b/d of fluids. They set
the pressure to the 440-psi optimum and gained 72 b/d of
production.
In another case, a dual-string gas-lift well had been dead
since 1996. With representatives of the operator, the service
team first identified the problem, then redesigned the gas
lift for optimal production from both strings using the lat-
est well data available.
After completing the gas lift valve change-out the team
restored production to both tubing strings.
The processes developed for installation design, well
analysis and operation procedures are implemented and
continue to be refined.
At the same time, the team has trained many of the
operator's field technicians so they could continue the
design work, handle the valve installation and conduct the
tuning operation.
Using that on-the-job-training approach, the fields had
increased production by 3,500 b/d at the end of the first
year. That figure rose to 4,000 b/d by the end of the second
year and has reached 4,500 b/d.
Of those gains, 40% came from the gas lift valve change
out and 60% resulted from casing-head pressure tuning. Ж

Well Thought Out Intervention
An operator faced plug and abandonment before using theWeOServ*"1 four-step solution,
Cost-effective well interventions share four elements: 1]proper diagnosis of the problem; 2) practical solutions; 3}successful implementation; and 4) follow-up verification.The case history below demonstrates how Weatherford'sWellServ Intervention Services use this process to help oper-ators save their wells in situations that previously seemedunsalvagable.
SituationA South Texas operator re-entered a gas well that had pro-duced more than 5 Bcf of gas since 1985. The operator hadcontracted another service company to recover 27/8-in.,11.65-lb, 22% chrome tubing inside 5l/2-in., 23-lb casingfrom the sour well to allow a deeper completion, but wasunsuccessful. The string was stuck at 5,500 ft [1,677.5 m)when Larry Tidwell, Texas Gulf Coast sales representativefor Weatherford's WellServ operation, received an emer-gency call. The WellServ team had to use two solutions tosolve the problem, which made the difference between sav-ing the well vs. abandoning it
Solution #1Diagnostic-After consulting with the operator and reviewingprevious attempts to back off the pipe, the WellServ teamrecognized it couldn't precisely locate connections in thestring because the chrome metallurgy blocked magneticreadings.
Engineered Solution-The WellServ team suggested run-ning a 40-ft (12.2-m) string shot to assure it crossed a con-nection instead of using a collar locator and a conventional6-ft [1.8-m) primarcord shot
Implementation-With the string shot in the hole, theteam applied left-hand torque to the tubing and fired theshot The connection broke, allowing the first joint of pipe tobe recovered.
Verification—The string shot system worked well enoughto do the job down to 13,000 ft [3,965 m), but then torque
The WellServ team was able tocut the pipe in an hour and ahalf from rig-up.
transfer would notreach the connection.A second solution wasrequired to continuerecovering pipe.
Solution #2Diagnostic-Recovering additionalpipe meant cuttingthe tubing. This rela-tively simple task,however, was compli-cated by two factors:1) cutting choices nar-row drastically withtough chrome tubingwith a .422-in. wall thickness and an inside diameter of only1.99-in.; and 2) all cutters won't work with a bottomholetemperature of 330T [1G5.39°C) and pressure of 6,500 psi.
Engineered Solution-Became a chemical cutter couldn'tcut through that degree of thickness and a jet cutter wouldhave flared the pipe (and both would have preventedfishing operations), WellServ called on its partnershiparrangement with MCR Oil Tools to use the ExtendedReach (Slim) Radial Cutting Torch. The chosen model forthis job was the 11/2-in.-diameter tool. Additionally, becausethe cutting torch was non-explosive, the WellServ teamcould hotshot it from Lafayette, La., to the South Texaslocation without the red tape associated with the trans-portation of explosive materials.
Implementation-The team ran the cutter into the holeto a depth of 13,588 ft [4,144.34 m), set it and applied directcurrent to generate the L200T (648.24°C) needed to ignitethe special compound, which reached a temperature of6,OOOT [3,312.24'C) and melted through the chrome tubing.
Veiification-At the end of the two-week job, the teammade the cut in an hour and a half from rig-up. Since thismethod of cutting does not alter the diameter of the tubular,the operator was able to continue his fishing operation. ^

DrillShoe™ III Cuts Costsfor Shell BruneiEfficiency offers longer life for country's oldest field.
The oil field has an aging issue, including a growing numberof old fields that need to be maintained. Weatherford'sDrilling with Casing technology improves drilling efficiencyby eliminating time spent running casing.
SituationRoyal Dutch/Shell opened operations in the sultanate ofBrunei Darussalam in 1913 after finding oil in Miri field inadjacent Sarawak, Malaysia. It was the only company thatremained in the country through a host of non-commercialdiscoveries until it persevered with the nation's first commer-cial discovery at Seria field on Brunei's western coast in 1929.
Seria was Brunei's only producing field until 1960, andShell Brunei Petroleum has studied, tested and inventedways to maximize reserves and production throughout thefield's long life. It produced the field's billionth barrel of oilin 1991, and it continues to produce 26,000 b/d from Seria.
Shell Brunei has optimized production by constantlylooking for ways to get maximum production at the lowestcost. While pursuing that mission, the company evaluatedWeatherford's Drilling with Casing (DwC™} system withthe company's exclusive DrillShoe III on its S-816 well inSeria field.
SolutionUsing the system, an operator can drill with casing to a tar-get depth and cement the casing in place through the cas-ing bit At that point, the operator can drill throughDrillShoe III with a smaller casing size or a standard drill-string. The cutters on the bit unfold from the DrillShoeface like fingers opening from a fist to rest out of the wayin the well's annulus.
KCA-Deutag's T-41 rig with a top drive took the job ofdrilling the 12-in. hole from 194 ft [59 m] to 2,366 ft (721m)using the DwC system with a drillable casing bit andWeatherford's L42W1 large bore float collar at the bottom ofthe hole.
The casing string was 95/8-in., 47-lb/ft, New Vam L80 with

Weatherford's 95/8-in. inside diameter, 121/4-in. outsidediameter DrillShoe III on the business end.
The drilling team used a potassium chloride/polymermud weighted to 9 ppg in the hole.
In the record-setting well, the bit was on the bottom for44 hours for a penetration rate of 49.2 ft/hour (15 m/hour)through the clay and sandstone section.
ResultsAt the completion of the test, the drilling team hadcompleted the world's longest run of any DrillShoe modelat 2,172 ft (662 in), and it accomplished the deepestDrillShoe setting depth at 2,366 ft (721 m).
As important as the physical records, the trial run in fieldconditions - matched against optimized, previously drilledwells - showed drilling with casing with a drillable bit wascost effective and belonged in the Shell Brunei engineeringtoolbox for appropriate wells. Meanwhile, the operator haseliminated one of the more hazardous operations in drilling,the rig floor operation of making up the drillstring.
On this first test run, at the highest cost point on thelearning curve, the S-816 well did not show a cost savings,but the results were good enough to show Shell engineersthat the technique and the technology worked as promised,and negotiations are underway for additional DwC wells. ^

Johnson Screens,
Weatherford screens are critical in thousands of applica-
tions, from the water we drink to the energy we consume.
They are important components used to produce the
paper we write on, the food we eat and the clothes we
wear. In the realm of vital screen technology, Weatherford
has a leadership position in practically every screen market
in which they participate.
This market dominance did not happen by chance. A
series of strategic moves culminated Nov. 30th, 2001, with
the addition of Johnson Screens to the Weatherford family.
Celebrating its 100th anniversary this year, Johnson Screens
has a rich, innovative heritage in the marketplace. Founded
in 1904 in St Paul Minn., the company has long been the
brand leader in screen design and manufacturing. It has
principal manufacturing operations in Houston; New
Brighton, Minn.; Chatellerault, France; Dublin, Ireland; and
Brisbane, Australia. The company services the oil and gas,
waterwell, mining, petrochemical, pulp and paper, water
process, and food and beverage industries, providing welded
profile wire screen in a wide variety of configurations.
Because of the synergies between the existing
Weatherford screen business and Johnson Screens, the
integration has gone well, especially on the oil and gas side.
From the beginning, management felt the products offered
a good fit In many cases, Johnson had a strong position
where Weatherford did not In those areas where both
companies had strong market presence, the combination
helped improve the company's earnings position through
consolidation.
The benefits of the integration have been impressive.
No other screen provider - and this applies to any industry
Weatherford screens serve - brings the same level of
engineering and design focus, expertise or global manufac-
turing footprint And, through the company's combined
size and economies of scale, Weatherford can offer greater
value to its customer base.
A high percentage of the screens business unit work-
force has been with the company for more than 10 years.
And company wide, the group has one of the highest
percentages of senior, tenured employees - those having
25 years or more on the job. This experience level brings
with it certain competitive advantages as well as a solid
position for future growth.
On the oil and gas side, Weatherford is uniquely
positioned to be the leader in offering their customer
base mechanical sand control solutions. Within its other
operating industries, the company has done some unusual
things and expanded into some different markets. Of
particular note, they are now working on a significant
architectural screens project for the rebuilding of WTC7 at
the World Trade Center site.
Other growth areas remain. Opportunities exist for oil
and gas refinery workovers, not only for specialty screens
used in catalyst conversion, but also for solid expandables
and recladding operations within refineries. In non-tradi-
tional oil and gas applications, such as coalbed natural gas
production, screens are an important element in pump
protection. And in mature oil and gas producing provinces,
increasing water incursion is driving reservoir instability
and escalating sand production, increasing the need for
screen products to control sand downhole.
Given the breadth and depth of experience across
industries, Weatherford is now poised to increase market
penetration and technical innovation. It is reassuring to
have a 100-year heritage of engineering and manufacturing
excellence to rely on as the company moves forward. ^

As important as new technology is in gaining efficiency andcost advantage, it is also necessary to find the best way todeliver that technology to the client More and more, obvi-ous value exists in assembling a broader package of serviceswhen projects are viewed as an integrated solution ratherthan a series of unrelated operations.
However, it is also critical to understand that no companyhas every tool and all the expertise for every phase of a givenproject's life. That reality was often overlooked in the "inte-grated services" era when some companies tried to be every-thing for every client
Weatherford's more practical solution is to bundle itsservices where the strategy makes sense for the customerin a particular application. Bundling - grouping productsand services, possibly across division lines - reduces thenumber of interfaces between Weatherford and its clients.For example, providing two or more services on a locationmay call for a coordinator.
Ron Gordon, Director, Project Management, heads across-divisional group in the new organization charged withincreasing the ability to bundle services and systems withinand across Weatherford's new divisions.
"Weatherford wants to take a lead role in projects,instead of just being called when a packer is needed," saidGordon. "It allows us to use new technology in a moreeffective manner."
The goal is to create a semi-autonomous unit that pro-vides best-in-class project management for "hydrocarbonvalue-based" risk/reward contracts. Strong project manage-ment competencies include geological/geophysical, drillingand reservoir engineering.
"That will give us access to new opportunities, includinglarger and longer term projects," said Gordon. "And it's agood way to leverage our technology to add value for ourcustomers."
One angle that highlights the bundled services and sys-tems strategy aimed at lowering drilling and field operatingcosts and improving recovery is the Total Tubular ServicesCITS) program, which manages every aspect of the tubularprogram, from arrival of the pipe in the country to installa-tion in the well to the return of unneeded pipe to stock.

The bundling of tubular services also provides pull-through opportunities for other Weatherford productsand services, including the ones shown above.
Total Tubular Services ProgramFew elements of well construction and field exploitationinvolve a larger variety of equipment and services - and tra-ditionally, companies - than the acquisition and installa-tion of pipe and related completion equipment
More efficiently managing a tubular program from welldesign through installation and production can cut drillingand field development costs and operating expenses.Consequently, bringing order and efficiency to the processis not a new idea.
But Weatherford, with the help of its alliance partners,freshened up the idea, added some new services and creat-ed the TTS program.
"It is a solution rather than a 'callout' service," said FrankMathews, Vice President, Rental &f Tubular RunningServices. "Weatherford can take on the responsibility fortubulars from the mill to the wellbore, creating value forthe client It is a true project management effort, requiringcoordination of transportation and handling, inspectionand preparation, engineering support and documentation."
The solution begins with arrival of pipe in the country,includes installation in the well, and even extends to man-aging the return of unused pipe and equipment The serv-ice is especially appealing in an area where the client doesnot have sufficient infrastructure.
But even where infrastructure is adequate, operatorstaffs are stretched thin. And with broad responsibilities,they don't have the time to become experts on managingthe details of a tubular program.

bundled strategies
"Weatherford can get subject experts together to capitalizeon synergies," said Mathews. "We can take advantage of ourlong experience in running pipe and downhole accessories,team this with our service capabilities, and ultimately elimi-nate redundancy from the supply chain process."
Important elements in the success of the Total TubularService are Weatherford's 440 locations in more than 100countries, and adherence by Weatherford and its alliancepartners to international quality standards, including thoseof ISO9001/ISO9002 and API.
The BenefitsFor the customer, TTS offers a more efficient administra-tion process that can bring a direct reduction in well costThere is one contract to negotiate and administer; a singlepoint responsibility, and a single billing structure stream-lines operations and facilitates measurement and control.And TTS makes it much easier to coordinate all work activi-ties, making it possible to reduce the number of supervi-sors, both local and expatriate, for each onshore operation.It all improves supply chain management, with benefitsboth to Weatherford and to the customer.
The TTS strategy also eliminates the need to preparetubulars offshore and greatly reduces the risk to the off-shore environment that might result, for example, from

In addition to greater efficiency for Weatherford andtheir client, the bundling of tubular services provides "pull-through" opportunities for other Weatherford products andservices, including casing running, hammer drilling, completion and inspection services, fishing equipment and services,drilling equipment, supply management services and more.
TTS in actionWeatherford's Phillips China Inc's Phase 1 Penglai 19-3operation, used onshore preparation services and reducedtheir costs by 20% when compared with the costs of usingseperate tubular services operations. Services includedtrucking the pipe from Xingang Port to the onshore facilityand offloading. Then when ready to go offshore, tubularswere transported to the dock.

A Weil-RoundedFull CircleWhen Chris Ball began marking as a roustabout on aNorth Sea oilfield in 1979, he had no idea that the experi-ences he was gaining and the connections he was makingwould be valuable far a job 24 years down 'the- road,
"I learned a great deal while working as a roustaboutbecause at that time, it was quite typical to quit one rig, walkonto another, and get a new job," says Chris. "I started on theBrent Charlie platform, moved on to semi-submersibles andfinally to drillships."
These years were also beneficial for Chris when it comesto connections.
"During my four years as a roustabout, I worked withpeople from all over the world - some that have sinceresurfaced," he says.
In 1983, Chris joined Weatherford in the Middle East as aJoint Analyzed Makeup (JAM) technician. Since then, he hasworked for the company in multiple locations - Abu Dhabi,Algeria, Dubai Trinidad, the United States (Houston) andthe United Kingdom - in a variety of positions: drill crewmember, helium-operated leak detection/JAM supervisor,department supervisor, regional operations supervisor, dis-trict manager and well installation services worldwide train-ing manager.
Now all of that experience is coming to bear in Chris'srole as the Weatherford U.K Training Center manager, aposition and discipline that has taken on greater focus aspart of Weatherford's Enterprise Excellence Process (EEP).(For more information, see related article on page 22).
A key component of EEP, one for which Chris is wellprepared, is to improve the value of employees in their cur-rent roles and their potential for advancement
"I feel that the different positions I have held over theyears, as well as the variety locations in which I have livedand worked, enable me to provide a better training environ-ment," Chris says. "My experience allows me to talk to boththe commercial customers and Weatherford employees withan equal understanding of both of their needs."

"Back in those days, if someone got hurt while workingon the rig, they waited for a medic while everyone else con-tinued to work as if nothing happened," Chris remembers."But now, even minor injuries shut down the entire opera-tion, and this can be quite costly for operators."
Likewise, Chris also has seen Weatherford make majorstrides in workplace safety. For example, he taught Safe Start,a course designed to increase employee awareness of safetyon the job, to 400 Weatherford employees last year. *V

In 2003, Bernard J. Duroc-Danner,
Weatherford's chairman and chief exec-
utive officer, decided to re-focus the
corporation on its core elements, one
of which was re-kindling Weatherford's
culture of excellence.
To emphasize this comrnitmentDuroc-Danner appointed Keith Morley

team charged with helping each
employee enhance every aspect of
excellence in their daily activities. Thefollowing interview with Keith gives
some background about why the pro-
gram is much more than the more
familiar Quality programs of the 1990s.
Q: What are the business drivers
behind Weatherford's Enterprise
Excellence Process?
A: More than ever, the financial
and operating challenges facing our
customers demand innovative technol-
ogy, reliable equipment and effective
processes. To meet those demands,
Weatherford's Enterprise Excellence
Process (EEP) focuses on creating a
preventative culture with error-free
performance. The process addresses
everything from total technical integri-
ty assurance for products/service deliv-

ery (including ISO, API or similar
standards of quality management
systems in our manufacturing and
service centers) to continuous processimprovement in our day-to-day
activities with both our internal and
external customers.
Issues such as personnel compe-
tency, performance tracking, strategic
customer alignment design validationand various aspects of safety, security,
health and environment are some of
the key modules of the EEP. The scope
also extends to processes related to our
corporate and social responsibilities.
Q: Ною was the program developed?
A: The first step was pulling
together an EEP Steering Team. This
10-member steering team is not a cor-
porate quality department, the quality
police or a source of funding for qual-
ity initiatives. Rather, it is a cross-divi-
sional, cross-functional, multidisci-
pline task force. The team is empow-
ered to drill down into the organiza-
tion to assess the current perform-
ance of our quality and business man-
agement systems, identify best prac-
tices and champion uniformity of
methods, tools and reporting that will
support our excellence improvement
activities on a global basis.
The next step was conducting ini-
tial assessments of our current quality
and business management systems.
The team visited a range of geographi-
cal locations and different business
units, resulting in the identification of
various best practices that currently
22 I W Magazine I 20O4 First Quarter
ЕЕР
exist within the enterprise. These best
practices, supplemented with other
world class processes, are being used
as the foundation blocks for our
global quality and business process
improvement activities going forward.
For instance, we recommended
incorporating PGA cultural training as
a building block for EEP's quality man-
agement process improvement tech-
niques after seeing how well it worked
at our Gemoco facility in Houma, La.,
and within our drilling and well serv-
ices organization in Norway. Both of
these organizations had maintained the
Philip Crosby, QIT cultural training
techniques as core processes within
their organizations. The QIT culture
empowers everyone from shop floor
personnel to top management to iden-
tify opportunities for improvement, cre-
ating an environment that promotes
continuous process improvement.
Client input also played an impor-
tant role in the initial development of
our EEP. We had excellent input and
contributions from BP in terms of
understanding the customer viewpoint
They helped us improve the design
and implementation of various aspects
of the process by sharing their experi-
ences and lessons learned in their
Global Quality Improvement Process,
which they have actively been imple-
menting for a number of years.
Q; What does EEP focus on
specifically?
A: The Steering Team, in collabora-
tion with Weatherford's Executive
Leadership, has identified seven areas
of improvement that with immediate
focus on the development of uniform
global practice, will enhance our oper-
ating performance and technical
integrity. Cross-functional teams are
assessing these improvement areas, or
"modules," to determine the scope,
functional requirements and appropri-
ate tools that are required to allow uni-
form application throughout
Weatherford. The modules under
review are:
1. Quality Management System
2. Performance Tracking
3. Personnel Competency
4. Equipment Maintenance
5. Strategic Customer Alignment
6. Design Validation and
Commercialization
7. Customer Requirements
Verification
Another improvement opportunity
we identified was the need for a docu-
mented, uniform set of performance
expectations or standards. As a result,
we published Weatherford's Enterprise
Excellence Management System,
Expectations Document This docu-
ment addresses the Seven Elements of
Excellence (see graphic at right) mat

Excellence Management System
The 7 Elements are based upon the
five core components of ISO 9000,
which include a documented Quality
Management System, Management
Responsibility, Resource Management,
Product &f Service Realization, and
Measurement-Analysis-Improvement
To these, Weatherford added Risk
Management and Health, Safety,
Security &f Environment to emphasize
the critical importance of these two ele-
ments to Weatherford. Under the head-
ings of these seven elements, we have
defined clearly what Weatherford
requires of our management and our
employees as we conduct our daily
business.

Q: How will it benefit customers and
suppliers?
A: For our customers, the EEP
process results in significant advantages
(EEP framework on page 22]. For
instance, enhanced uniformity through
common processes will produce greater
efficiency and more effective planning.
EEP also will provide processes that
yield better discipline in capturing cus-
tomer requirements. As a result, non-
conformance in the delivery of products
and services to the external customer
is reduced and the completion of pro-
cesses in an error-free manner for our
internal customers mean that efficiency,
performance levels and ultimately our
value are each raised. This value
increase is quickly realized through
greater customer confidence, optimized
performance and reduced downtime.
For our suppliers, we can provide
better discipline in specifying require-
ments, which reduces non-confor-

40 Million Contract Awarded for Underbalanced Drilling
Weatherford's recent four-year contract extension, which
was announced Jan. 12, solidifies its platform for contin-
ued growth in the Middle East and North Africa.'••'- • • : ;©s!?f! • i ij|i
The contract extension will enable the company to pro-
vide underbalanced drilling systems (UBS) for Petroleum
Development Oman (PDO), a joint venture with Shell. ;
The contract was extended because of the proven• *'".-• :;:'.;
productivity, safety and cost benefits from using
Weatherford's UBS packages; as well as PDQ's identification
of underbalanced drilling as a key technology to help offset
declining production rates from mature Omani reservoirs.
Since June 2002, PDO has drilled 28 wells with
Weatherford UBS as part of a multi-well program to evalu-
ate the technology's economic and operational benefits. In
the first phase, PDO drilled 14 wells underbalanced in the
Nimr field in Southern Oman.
In the second phase, the underbalanced re-entry proj-
ect exceeded - and in some instances tripled -forecasted
production rates. All wells met or exceeded key perform-
ance indicators that were based on quality, health, safety
and environment performance; increased well deliver-
ability; and overall operational efficiencies. This phase of
the project also has yielded significant costs savings when
compared with the initial campaign.
"Together with Weatherford UBS, PDO has gone up a
huge learning curve in these campaigns, both from an
operational viewpoint, where efficiency has increased
tremendously, and from our reservoir understanding.
Safety is our top priority, and we are very pleased that the
campaign has been implemented without any underbal-
anced drilling-related incidents," said Paul Francis, PDO
Underbalanced Drilling Implementation Team leader. "We
are highly satisfied with the project's outcome and antici-
pate further spread in the use of underbalanced drilling
over the next four years."* "
The current third phase of PDO's unde.• ' - . . . ' .
program involves Weatherford drilling more complex
underbalanced drilling multilateral wells in the southern
Omani oil fields.

Weatherford has signifi-
canuy broadened and ele-
vated its product portfolio
since its humble begin-
nings as a centralizfr and
scratcher company in
1948. However, much of
the company's reputation
for service and responsive-
ness stems from what me
term our classic core, tech-
nologies...tlie well con-
struction, drilling tools,
fishing tools and otter
services that clients have
come to associate witii the
Weathetford mane. This
column's purpose, is to
highlight those classic, seg-
ments and the mle they Weatherford entered the tubular running services business in 1959 when manual casingplay in "Weutherford today, tongs were still the only option for operators.
The decade of the 1970s, one otherwise known for events
such as the impeachment of U.S. President Richard Nixon
and the Vietnam War, was also a crucial turning point for
Weatherford as a company
Why? It marked the creation of our tubular running busi-
ness, which, with more than 400 sets in service, held the
world record for the largest long inventory.
Weatherford's foray into tubular running started in 1959
with a traditional offering of standard casing tongs. In an
effort to continue developing a breadth of product and serv-
ice offerings, Weatherford acquired Lafayette, La.-based Lamb
Industries, Inc. in 1975, which added hydraulic tong technol-
ogy to the company's already strengthened portfolio.
This acquisition brought the Model 16 tong and the Joint
Analyzed Make Up QAM®) system, both of which are still
used around the world today, into Weatherford's tubular
running portfolio. JAM was the first commercial torque
turn computer monitoring system, which provided more
efficiency and less room for error for operators. The Model
16 tong, known in the industry today as the 16k tong, was
the first gated rotary-power tong. The Model 16 was easier,
safer and more versatile because of a smaller and lighter
profile, and higher torque output capability.
Today, we continue to evolve our tubular running services
offering. Aside from the JAM and Model 16, we also devel-
oped the industry's first mechanized rig systems and a vari-
ety of other innovations, ranging from casing handling to
developing a total tubular management package (see related
article on page 18}. ^
