WELLSITE FORMATION PRESSURE CONSULTING

Diversified Well Logging is proud to be able to offer a team of experienced formation pressure engineersRealtime services are provided at the rigsite, remotely, and a combination of bothPre-drill studies and geomechanical modelling will be providedPost-drill pressure and geomechanical evaluation will be performedOperational experience includes land, deepwater, and high pressure/temperature environments

DWL’s Mud Logging and Drill Monitoring fully complement our FORMATION PRESSURE consulting



The evaluation of formation pressures is an integral part of the well planning process. In order to drill a well safely and economically it is necessary to know the pore pressure and fracture pressure. Pre-well studies give a best estimate of the well’s pressure profile, while realtime evaluation allows modification of the profile and successful completion of the well

Diversified Well Logging will be a valuable partner at each stage of the process



DWL’s formation pressure consultants will utilize any and all data sets available to them

▪ Pre Drill▪ Surface geophysical

▪ Regional geology

▪ Seismic data

▪ Offset data

▪ While Drilling▪ Drilling exponents, drilling data

▪ MWD/LWD parameters

▪ Drilling fluid properties, circulation parameters, gas, temperature

▪ Geological data, rock properties, cavings volume

▪ Post Drill▪ Casing point logs

▪ Final well logs

▪ Pressure test data

▪ Data analyses



Diversified is software ‘neutral’. Our consultants have expertise in all commonly used applications

▪ DrillWorks Predict

▪ IKON RokDoc RT

▪ Jewel Suite

▪ And others …

Diversified will use the client’s software of choice



Communication is key to any successful serviceWith a formation pressure service, timely communication is critical Diversified’s consultants follow strict protocols for daily reports and in the case of abnormal eventsDaily reports include all quantitative and qualitative pressure indicatorsFor abnormal events, consultants will communicate immediately with client personnel as outlined in thepre-well Communication Protocol



Diversified Well Logging’s Formation Pressure Consulting Service is focused on

REDUCING RISKIMPROVING DRILLING EFFICIENCYREDUCING COSTS through REDUCED NPT*

*A 2009 survey by Welling & Co., found that the highest time percentage of non-productive time (NPT) is related to geomechanics and pressure related issues – around 37%; this equals about 25% of drilling costs. On a $100M drilling project, the possibility exists to save up to $25M when using realtime FORMATION PRESSURE CONSULTING.


WELLSITE GEOLOGY

The Wellsite Geologist, as the source of all operational geologic information, is the most important link in the chain of communications between wellsite and management. He is the exploration department’s man-on-the-spot with the responsibility for obtaining every possible scrap of information and insuring that the data are accurate and reliably transmitted to the client

DWL’s Wellsite Geologists are fully aware of their responsibility for all geology and geological activity


WELLSITE GEOLOGY

Responsibilities include, but are not limited to:

▪ Safety aspects of operations under their responsibility▪ Supervising mud logging operations▪ Supervising wireline operations▪ Supervising MWD/LWD operations▪ Picking casing and coring points▪ Communication at and between rigsite and office▪ Daily reports and log quality▪ Data verification, storage, and transmission


WELLSITE GEOLOGY

Diversified Well Logging’s Wellsite Geologists are experts in their fieldExperience extends over the major plays in the continental USAOffshore experience covers shallow and deepwater blocks in the Gulf of MexicoMost have had years of experience working around the world

DWL’s Wellsite Geologists will assure delivery of reliable dataData that will ensure accurately evaluated formationsAnd successfully completed wells

GAS QUALITY and ANALYSIS


Diversified Well Logging is committed to delivering the maximum value from its dataFormation gas is an important source of ‘first-look’ formation and reservoir evaluationA multi step approach is taken to ensure that gas data quality is assured

For DWL, Quality Controlled equals Quality Assured



Realtime Quality Control

Daily Regional Review

QC Specialist Oversight

Gas Quality Process

Data reviewed and issues reported back to source for correction

Issues explained/corrected and data returned for new review



DWL’s Gas Quality and Analysis process can provide pre-well insights for new projectsUsing offset LAS gas data and logs, expected gas curve and ratio profiles can be providedGas ratios will be used to

▪ Identify formation tops▪ Identify changes in formation fluid▪ Indicate porosity changes▪ Pick out anomalous trends▪ Provide correlation points while drilling

Using pre-well studies and realtime expertise, DWL’s Wellsite Geologists and Gas Analysts will provide data that can be trusted; data that will increase geological certainty and be invaluable for future field and regional studies. Much of this data can be integrated into DWL’s Geosteering programs for more accurate wellbore positioning and successful completions

All of DWL’s Wellsite Consulting Services aim to add value way beyond their cost
