NOTE:
DESCRIPTION OF CUTTINGS SAMPLES
Words having a quantitative connotation were used
in describing sedimentary packages involving a
repetitive series of lithologies. These words and
their significance were:
1. Alternating - two main rock types, each
comprising between 60% and 40% of
the series
2. Interbedded - between 40% and 20%
3. Minor - between 20% and 10%
4. Trace - under 10%

SUMMARY
A Vertical Seismic Profile (VSp) was conducted in Poeppels Corner #1 on 21st September 1984. Eighty-six levels were shot using an airgun source the majority of which have been used in the VSP processing.
The objective of the VSP was threefold:
1) - to determine the mUltiple content of the area by analysis of the downgoing wavetrains.
2) - to get a better tie between the Geogram and Seismic. This is due to the fact that the lateral depth of investigation of a VSP is intermediate between surface seismic and logs (radius 20 meters).
3) - to obtain a high resolution time-depth curve. As the levels are separated by only 2 to 16 milliseconds, accurate velocity analysis can be made.
In addition to the above the VSP has other applications:
a) - Further analysis of the downgoing wavetrain provides information on the earth filtering of the seismic wave versus depth.
b) - The VSP has the properties of being Vertical, therefore minimising the effects of moveout. This simplifies greatly the analysis of highly dipping reflectors, and also the interpretation of data recorded in faulted areas.
c) - One of the most important applications of VSP's is the analysis of reflected signals below the sensor.

A total of 86 check levels were shot with the number of stacked and rejected shots for each level being sh,own in the table above. The check levels at 8500, 5050,4990,4980,4970,4300,3505 and 3500ft below KB have been omitted from the VSP and sonic calibration processing. In most cases the geophone has been moved to nearby borehole positions in order to improve the signal to noise ratio. Check levels shot between 8400ft and 2350ft have been used in the VSP
processing. Above 2350ft the levels at 2070 and 1100ft below KB have also been omitted from the sonic calibration processing due to poor quality signals.
The general data quality was good and a plot of the stacked check shot data (Figure 1) has been included as Plot 1 of the VSP displays.
Page 6 SONIC CALIBRATION
Purpose: To adjust the sonic log using the vertical times obtained at each check level.
Method: A "drift" curve is obtained using the sonic log and the vertical check level times. The term "drift" is defined as selsmic time (from check shots) minus sonic time (from integration of edited sonic). Commonly the word "drift" is used to identify the above difference, or to identify the gradient of drift versus increasing depth, or to identify a difference of drift between two levels.
The gradient of drift, that is the slope of the drift curve, can be negative or positive.
For a negative drift ~drift <0' and tbe sonic time is grea.ter Adeptb
tban tbe seismic time over a certain section of log.
For a positive drift .~ drift >0' and tbe sonic time is smaller 4depth
than the seismic time over that section of log.
Tbe drift curve, between two levels, is then an indication of the error on the integrated sonic or an indication of the amount of correction required on the sonic to have the TTt of the corrected sonic match the check shot times.
Two methods of correction to the sonic log are used.
(a) Uniform or block shift.
This method applies a uniform correction to all sonic values over the interval. This uniform correction is applied in the case of positive drift and is the average correction represented by the drift curve gradient expressed in #s/ft.
(b) ~T Minimum
In the case of negative drift a second method is used, called At minimum. This applies a differential correction to the sonic log, where it is assumed that the greatest amount of transit time error is caused by the lower velocity sections of log. Over a given interval the method will correct only At values which are higher than a threshold, the At minimum. Values of At which are lower than the threshold are not corrected. The correction is a reduction of the excess of At over At minimum, At - At min.
At - At minimum is reduced through multiplication by a reduction coefficient which remains constant over the interval. This reduction coeffiCient, named G, can be defined as:
G = 1 + Drift "'JI":"(~-:-t----:'~-t-m--:-in~i:-m-um--=-)~dZ-
Where drift is the drift over the interval to be corrected and the value J(At - At minimum)dZ is the time difference between the integrals of the two curves ~t and At minimum, only over the intervals where At> At min.
Hence the corrected sonic: At • C(At - At min) + At min.
Page 7 SONIC PROCESSING
OPEN HOLE LOGS
Both the sonic and density logs used in this report have been edited prior to input into the WST chain. The sonic curve was affected by noise spikes and cycle skipping which have been edited with straight line patching. No density logs were available above 4530ft below KB and so a constant density of 2.4gm/cc has been used above this depth.
To follow the client request of using a replacement velocity of 6000ft/s down to 0.5s no open-hole logs have been used above 1500ft.
CORRECTION TO DATUM
Seismic reference Datum (SRD) is at 300 feet above Mean Sea Level. The airgun was positioned 19ft below Ground Level (188ft below SRD). ARCO AUSTRALIA LTD. requested a replacement velocity of 6000ft/s between SRD and 0.5s TWT (1500ft). To obtain this a velocity of 6290ft/s was used between gun depth and 1500ft below SRD (Based on the transit time from the check level at 1300ft below KB) and a velocity of 4539.42ft/s was input between SRD and gun depth. This resulted in an average velocity of 6000ft/s to 1500ft below SRD and a correction from source to datum of 41.42ms.
SONIC CALIBRATION RESULTS
The top of the sonic log (in this case 1500ft) is chosen a~ the or1g1n for the calibration drift curve. All drift measurements are relative to this point.
The drift curve is noticeable for the large amount of scatter of the drift points. There is no obvious reason for this, especially considering the good quality of the check shot data. However there are some well defined trends on the drift curve and these have been followed as closely as possible. The corrections applied are block shifts of 5.83 us/ft, 1.18 us/ft, 6.65 us/ft
and 1.26 us/ft over the intervals 1353 - 3120ft, 3120 - 3969ft, 3969 - 4601ft and 7386 - 8500ft respectively (depths below KB). Differential shifts using delta-t minimum values of 72.7 us/ft and 67.35 us/ft have been applied over the intervals 4601 - 5340ft and 5340 - 7386ft (depths below KB)
The adjusted sonic curve is considered to be the best result using the available data.

GEOGRAM PROCESSING
Geograms were generated using zero phase Ricker wavelets of various frequencies to pick the most suitable frequency to match the seismic section. The presentations include both normal and reverse polarity at IOcm/sec.
Geogramprocessing produces synthetic seismic traces based on reflection coefficients generated from sonic and density measurements in the wellbore. The steps in the processing chain are the following:
Time to depth conversion Generate reflection coefficients Generate attenuation coefficients Choose a suitable wavelet Convolution Output
Page 9 TIME TO OEPTII CONVERSION
Open hole togs are recorded from bottom to top with a depth index. This data is converted to a two-way time index and flipped to read from top to bottom in ord~r to match the seismic section.
REFLECTION COEFFICIENTS - ATTENUATION COEFFICIENTS
Primaries:
Sonic and density data are averaged over chosen time intervals (normally 2 or 4ms intervals). Reflection coefficients are then computed using:
where
R= ~,,-P,v.
P, ~+P, ~ p, = density of the layer above the reflection interface Pz = density of the layer below the reflection interface ~ = compressional wave velocity of the layer above the
reflection interface ~ = compressional wave velocity of the layer below the
reflection interface
This computation is done for each time interval to generate a set of primary reflection coefficients without transmission losses.
PRIMARIES WITlt TRANSMISSION LOSS;
Transmission loss on two-way attenuation coefficients are computed using:
2 2 2 2 = O-R, )( l-R 2 ) (l-R 3' ) ••• O-R n )
A set of primary reflection coefficients with transmission losses is generated using:
PrimarYn = Rn An_I
PRIMARIES PLUS MULTIPLES:
Multiples are computed from these input reflection coefficients using the transform technique from the top of the well to obtain the impulse response of the earth. The transform outputs primaries + multiples.
MULTIPLES ONLY:
By subtracting previously calculated primaries from the above result we obtAin multiples only.
Page 10
WAVELET
A theoretical wavelet is chosen to use for convolution with the reflection coefficients previously generated.
Choices available include:
Klauder wavelet Ricker zero phase wavelet Ricker zero phase wavelet Ricker minimum phase wavelet User defined wavelet
All wavelets can be chosen with or without butterworth filtering and with user defined centre frequencies. Polarity conventions are shown in Figure 2. These Geograms were generated using zero phase Ricker wavelets convolved with a lS-60Hz Butterworth filter.
CONVOLUTION
Standard procedure of convolution of wavelet with reflection coefficients. The output is the synthetic seismic data.
PROCESSING PARAMETER Page 11
PLOT #1 - STACK
All the raw shots after editing are stacked (or added together) to reduce noise.
PLOT #2 - BPF, TAR
After stacking a Band Pass Filter is used to filter out unwanted noise and True Amplitude Recovery to compensate for signal reduction with depth. The data is then corrected to SRD.
Band Pass Filter used : 14-60Hz TAR Factor : 1.2 Correction to SRD : -.041 Sec
PLOT #3 - VELOCITY FILTER
By adding and subtracting the travel time to each trace and then averaging over a number of levels, the upgoing and downgoing can be separated.
Number of levels averaged: 7
PLOT #4 - PREDICTIVE DE CONVOLUTION
By using the downgoing events to analyse the multiple content, parameters can be picked (predicted) to remove (by deconvolution) the multiples from the upgoing wavetrain.
The PDN parameters used:

PLOT #5 - WAVESHAPE DECONVOLUTION
By using the downgoing events after PDN to analyse the remaining multiple content, parameters can be selected to further deconvolve the wavetrain using a known wavelet (Zero or Minimum phase).
The WSF parameters used:

PLOT #6,7 - VSP/GEOGRAM
The upgoing events after WSF are then stacked and displayed with the upgoing from WSF and Geogram. Two stacks are made, one using all data and the other only using the first lOOms of each wavetrain. The latter should simulate the reflectors at the borehole.
Plot #6 contains data using Normal Polarity.

b. Prognosis
Poeppels Corner No. 1 was an exploration well drilled on the crest of
a dip closed anticlinal structure in the western flank of the Eromanga
Basin. The main objectives were lower to middle Jurassic non-marine
sandstones of the Poolowanna Beds. Secondary objectives were Triassic
sandstones of the Peera Peera formation. Other wells drilled in the
area include Thomas No. 1 and Poolowanna No. 1 and data from these .
wells was used for correlation and estimating normal pressure gradients.
Exploration Logging provided a standard mudlogging unit equiped with
a drill monitor panel, shale density kit and autocalcimeter. In addi
tion to the conventional mudlogging and formation evaluation services
provided from spud to total depth, Exploration Logging also provided
a pressure evaluation service utilising the information recorded by
the drill monitor panel. The Operator was continuously advised as to
the status of these analyses and the results are presented in the
appendices to this report (see Appendix 1, Formation Evaluation Log,
and Appendix 2. Drilling Data Pressure Log).

2. DRILLING AND ENGINEERING
Poeppels Corner No. 1 was an exploration well drilled in south eastern
Northern Territory using Richter Rig No. 8. The well was drilled in 33 days
using 11 bits (4 tooth bits. 6 insert bfts. 1 core bit) which drilled for
a total of 338.5 hours at an average rate of penetration of 24.8 ft/hr.
Good, safe and generally efficient drilling practice was used and hole pro
blems were comparatively minor although some time was lost conditioning the
hole prior to running the 9.625- casing. No Significant hydrocarbons were
encountered.
26" and 17.5" Hole Section. 31 ft (GL) to 740 ft.
A 26" auger bit was used to drive the surface hole to 60 ft where the auger
bit snapped and had to be fished. During fishing operations the hole was
deepened to 63 ft where the 20" conductor pipe was run and cemented with the
shoe at 63 ft. The flowline. etc, was connected and NBll, a HTC OSC 3AJ 17.5",
was run and drilled to 740 ft at an average rate of penetration of 28.2 ft/hr.
At 740 ft returns were circulated. a wiper trip made with no problems, and
18 joints of 54.5 lb/ft, K55, 13.375" casing run and cemented with the shoe
at 723 ft.
12.25" Hole Section. 740 to 4540 ft.
The 12.25" hole was drilled from 740 to 4540 ft, a distance of 3800 ft, using
two tooth bits, in a total of 75 hours at an average rate of penetration of
50.7 ft/hr.
-4-
The Baps were nippled up and tested and NB#2, a HTC f3A,'was run and tagged
cement at 682 ft. The cement. shoe and new hole were drilled to 743 ft
using water. At 743 ft the drilling fluid was converted to a water-polymer
mud system but this became contaminated by the cement and had to be dumped.
Drilling then continued, using water, to 848 ft where returns were circu
lated and the water replaced with a water-polymer mud system and the bit
pulled to add stabilizers to the BHA. RRB#l, a HTC X3A, was run next and
drilled to 3249 ft before being pulled due to high bit hours and an in
crease in torque. Minor tight hole was recorded from the first few stands
of the trip out. On the trip in with NBI3, another HTC X3A, a bridge was
hit at 2256 ft and was reamed to 2315 ft. The trip in continued to 3126 ft
where the failure of a rig motor necessitated the suspension of the trip
while repairs were carried out. On resumption of the trip the hole was
tight and had to be reamed from 3126 to 3156 ft. By 3156 ft it was no .
longer possible to circulate, probably due to cavings/filt packing off the
BHA, and four singles had to be pumped out before circulation was regained
and the trip in could be completed.
NB#3 drilled to 4540 ft, with surveys being run at 3725 ft (1.75 degrees),
4260 ft (1.75 degrees), and at 4520 ft (1.25 degrees). At 4540 ft bottoms
up were circulated and the bit pulled. Tight hole was noted on the trip
out and the bit run back to bottom where returns were circulated to condi-
tion the hole and a high viscosity pill circulated to clean out the hole.
A 15 stand wiper trip was made with minor tight hole on the trip out and 43
ft of fill being reamed/washed on the trip in. Returns were again circulated
to further condition the hole, a 10 stand wiper trip made with no drag or
fill, bottoms up circulated and the bit pulled. Wireline logs were run,
-5-
with a wiper trip being made between logging runs and 119 jonts of K55
40 lb/ft. 9.625" casing were run and cemented with 330 sacks of Class G
cement lead slurry at 13.5 ppg tailed by 168 sacks Class G cement at
15.8 ppg. A wireline temperature log was run which indicated that the top
of the cement was at 2650 ft.
A saltwater-polymer mud system. with weights between 9.3 and 9.6 ppg, was
used in the 12.25" hole section. The hole condition was generally good,
however below 3250 ft considerable problems with cavings and fill occurred
and some time was lost circulating to condition the mud and to remove
cavings/ fill from the hole. The main source of the cavings appears to
have been from 840 to 1140 ft and from 1460 to 1540 ft. Both these zones
may have been slightly overpressured.
8.5" Hole Section. 4540 to 8500 ft (Total Depth).
The 8.51t hole section was drilled from 4540 to 8500 ft, a distance of
3960 ft, using one tooth bit, one core bit and 7 insert bits, in a total of
239.5 hours (drilling time) at an average rate of penetration of 16.5 ft/hr.
The BOP stack, flare line etc, were connected and successfully tested, the
12.25" BHA laid down and a slick 8.5" BHA picked up and NB#4, a HTC J04
run in. After drilling cement from 4450 ft. the shoe track and new hole to
4450 ft. bottoms up were circulated and a leak off test run. This test
indicated a formation fracture pressure of 14.1 ppg EMW. At 4616 ft a
negative flow check was made, bottoms up circulated and cement contaminated
-6-
mud dumped. Drilling continued to 4650 ft where bottoms up were circulated
and the bit pulled to add stabilizers to the BHA. NBNS was run in to the
shoe and the existing saltwater-polymer mud system replaced by a saltwater
gel-polymer mud system. The trip 1n was them completed with the last 11 ft
to bottom being reamed. Thirty klb drag was noted while making a connection
at 5546 ft and a high viscosity pill circulated to clean out the hole.
At 5664 ft bottoms up were circulated. a survey dropped and the bit pulled
due to bit hours and increased torque.
NB#6, a HTC J22. was run and, after reaming 10 ft to bottom drilled to
6506 ft where bottoms up were circulated, a survey dropped and the bit
pulled. NB#7, a HTC J33, was run in but only drilled to 6551 ft due to a
washed out nozzle. After replacing the nozzle and adding a junk sub to the
BHA RRB#7 was run and drilled to 6938 ft where bottoms up were circulated,
a survey run, and the bit pulled due to increased torque and high bit hours.
Minor tight hole was recorded on the trip out between 6938 and 6467 ft.
NB#8, another J33 drilled to 7421 ft, with bottoms up being circulated at
7022 ft and 7054 ft to check for possible shows. Forty klbs overpul1 was
noted on a connection at 7419 ft with high torque occurring while working
back to bottom. At 7421 ft bottoms up were circulated, a survey dropped
and the bit pulled with tight hole being noted from 7421 to 6761 ft.
The stack was successfully tested and NB#9, a HTC J44 run, with the inter
val 7359 to 7421 ft being reamed. After a drilling break at 7570 ft bottoms
up were circulated with 1.25 units of gas (from a coal) being recorded~
At 7829 ft bottoms up were circulated, a survey dropped and the bit pulled
due to erratic torque. The torque was probably due to a change 1n lithology.
-7-
HBI10, a J44. drilled to 7948 ft where bottoms up were circulated with
0.75 units of gas being recorded from a (fractured?) carbonate. At 8344 ft
bottoms up were again circulated, a survey dropped (misrun), and the bit
pulled due to high bit hours and decreasing rate of penetration. Minor
tight hole was again noted on the trip out from the interval 7307 to 7127 ft.
NBl11, a J33, drilled to 8469 ft where a deviation survey indicated an in
clination of 14 degrees. The high deviation was due to the bit following
the dip of the basement.
Drilling continued to 8490 ft where bottoms up were circulated and the bit
pulled to cut a basement core. Core No. 1 was then cut from 8490 to 8500 ft
and recovered 10.6 ft of metasediments and trachyte. Wireline logs were
run with wiper trips after the HOT and CST logs. Cement plugs were set
and Poeppels Corner No. 1 was abandoned as a dry well.
A saltwater-gel-polymer mud system was used in the 8.5" hole section with
properties sufficient to prevent any serious hole problems. Carbides were
run regularly, to checK for hole washouts and the effectiveness of the gas
detection system, and indicated that the hole was s1ightly washed out.
Minor overpull was noted from most trips through the newly drilled section
of hole. This was probably caused by slight swelling of hydratable clay
stones and shales.

No mud loses to the formation were recorded while drilling the well
and formation fracture pressures exceded mud hydrostatic at all times.
-9-
b. Formation Pore Pressure
Based. on the expected stratigraphy and data from the Thomas and
Poolowanna No. 1 wells a normal pore pressure of 8.6 ppg EMW was
assumed for Poeppels Corner No. 1. This was confirmed by RFTs run at
6729, 6770. 7041 and 7052 ft, all of which indicated formation pore
pressures of between 8.57 and 8.59 ppg EMW.
Dxc, bulk/shale density. gas. cavings, and hole deviation were all
continuously monitored as an aid to pressure detection but most proved
unreliable. Shale density and bulk density determinations were affected
by the lack of good shales and by the hydratable nature of most of the
clays. Gas values throughout the well were too low to detect any trip
or connection gases. if present. The interbedded and variable nature
of the lithologies and the absence of good claystone/shale sections
made Dxc values unreliable and difficult to interpret. Cavings/fill
and hole condition proved to be the best parameters for indicating, at
least qualitatively, changes in pore pressure.
The 17.5" hole section appeared to be normally pressured at 8.6 ppg
and there was no indication of abnormal pressuring 1n this section.
The parameters monitored while drilling indicated that the 12.25 t1 hole
was normally pressured at 8.6 ppg. However the amount of cavings and
fill seen after trips below 3249 ft and the splintery nature of these
cavings indicated the presence of minor overpressuring. The maximum
formation pressure was estimated to between 8.8 and 9.0 ppg EMW.
-10-
Wireline logs run at 4540 ft indicated that the intervals 840 to
1140 ft and 1460 to 1540 ft were significantly washed out and it is
probable that the overpressuring may have been restricted to these
zones.
The 8.5" hole section appeared to be normally pressured and no evi
dence was seen to indicated any abnormal pressuring. This was con
firmed by RFTs run at 8500 ft which gave the following results:
FORMATION DEPTH FSIP PRESSURE ft psi ppg EMW.
4708 2166 8.85 6729 2997 8.57 6770 3023 8.59 7041 3141 8.58 7052 3145 8.58
The RFT at 4708 ft was run in the top fo the Algebuckina Sandstone
and the slightly higher formation pressrue reading was probably due to
water drive in the sandstone.

4. GEOLOGY AND SHOWS
Poeppels Corner No. 1 was an exploration well drilled in the western flank
of the Eromanga Basin to test the hydrocarbon bearing potential of the lower
to middle Jurassic sandstones of the Poolowanna Beds. Triassfc sandstones
of the Peera Peera formation were also considered targets.
Exploration Logging personnel collected, prepared, described and packaged
cuttings and mud samples as per the requirements of Arco. Samples were
collected at 30 ft intervals from spud to 740 ft and at 10 ft intervals
from 740 to 8500 ft.
No significant hydrocarbon shows were recorded. Gas values ranged from
nil to trace with a maximum of 1 unit (200 ppm) from a coal at 7560 ft.
Because of the very low background gas readings carbides were run frequ~ntly
to check the sensitivity of the gas detection system and consistently gave
good results. No evidence was seen to indicate the presence of significant
liquid hydrocarbons, with only trace shows, mainly from carbonaceous material,
seen between 6550 and 7420 ft. The absence of hydrocarbons may indicate
a lack of seal 1n potential reservoir horizons.
The following lithologies were observed:

6715ft to 7350ft
This interval consisted of sandstone with interbedded silstone, shale and
minor coal. Gas values ranged from nil to 0.5 units, with Cl to C4 being
recorded. The gas was from coal/carbonaceous material. Aggregates of
fine sandstone although having no natural fluorescence, gave a very weak
milky white cut/crush cut fluorescence, probably from carbonaceous material
in the sandstone. Trace crush cut/cut fluorescence was also obtained
from siltstones and shales. Rates of penetration averaged 20 to 40 ft/hr
through the sandstones and 10 to 20 ft/hr through the siltstones.
The sandstone was clear to very light grey to light brown grey, friable

clayey in part, trace to common carnonaceous flecks, trace very fine
quartz grains in part, micro-micaceous. Grades in part to silty shale,
-17-
medium dark brown to dark grey, firm to moderately hard, subfissile to
fissile, commonly micro-micaceous and carbonaceous.
7350ft to 7690ft
This interval consisted of siltstone, grading in part to silty shale,
interbedded with lesser sandstone and minor coal. Rates of penetration
varied from 5 ft/hr in the s11 ty shale to 15 to 20 ft/hr in the sandstone
with drilling breaks of up to 60 ft/hr in the coals. Minor gas of up to
1 unit (Cl - C4) was recorded from the coals. Trace dull orange
fluorescence giving a very poor cut/crush cut fluorescence was recorded
intenmittantly from siltstone, sandstone and silty shale throughout this .
interval. The cut was probably from carbonaceous material.
The sandstone was very light grey to medium grey brown, friable to very
hard, dominantly hard, very fine to fine, occasionally medium, subangular
to subrounded, occasionally rounded, moderately sorted, common white to
light grey argillaceous matrix, common siliceous cement, trace lithics

The s1ltstone was light grey to medium grey brown, occasionally very dark
grey, firm to moderately hard, subfissile, common very fine "quartz grains,
common carbonaceous flecks and micro-laminae, micro-micaceous, trace

-~-
grey brown, firm t~ moderately hard, subfissile to fissile, commonly
carbonaceous and micro-micaceous, common silty material The coal
was black, hard, brittle, vitreous, conchoidal fracture, often very
argillaceous. The siltstone, silty shale and coal had a trace dull
orange fluorescence giving a weak milky white crush cut fluorescence
with a weak, very slow streaming, milky white cut fluorescence.
7690ft to 7826ft
This interval consited of chloritized talc which drilled at rates of
penetration varying from 5 ft/hr to 19 ft/hr and averaging 10 ft/hr.
Trace gas, all methane, no shows.
The chloritized talc was white to medium green, occasionally medium
yellow, soft to occasionally moderately hard, fissile, pearly lustre,
phyllitic texture, common metamorphic flow and recrystal1ized texture,
trace very dark grey, verY micaceous,carbonaceous grains, trace coarse
quartz grains with internally intergrown black mineral (tourmaline?)
interbedded with minor red shale and sandstone.
7826ft to 7940ft

and argillaceous matter, reI ic quartz grains often stress elongated,
trace disseminated pyrite especially along fracture planes, trace
radial pyrite growth, no porosity.
7940ft to 8496ft
The rocks in this interval were interpreted by EXLOG personnel as being
metasediments. However an examination of Core No 1, cut from 8490 ft
to 8500 ft, indicated that there was a strong volcanoclastic influence
in this section and it is probable that the metasediments also included
welded tuffs, igni'nlbrites, flows etc. Strong quartz, dolomite and
calcite veining was also common throughout this interval. Rates of
penetration varied from 6 ft/hr to 22 ft/hr and averaged 8 ft/hr. No
hydrocarbon indications were seen but from 8300 ft minor gas was
recorded. This was probably produced by the decomposition of polymers
1n the mud.
The metasediments/volcanics were white to bright green grey to medium
grey, mottled in part, hard to very hard, dense and massive to
occasionally fissile, common white to medium green grey (siliceous)
groundmdss with chloritic veins, bands and ellipsoids, common to abundant
cryptocrystalline to macrocrystal1ine calcite and dolomite veins and
crystals, common quartz veins, calcite, dolomite and quartz commonly
intergrown, very micaceous in part, schistose/phyllitic texture where
micaceous, rare acicular texture, rare ellipsoidal quartz grains with
-20-
"growth halo" texture, all grain boundaries diffused and intergrown,
grades in part to marble, no porosity.
8496ft to 8500ft
This interval was seen in the bottom part of Core No 1 and consisted
of a trachyte/diorite which was very dark grey to black, melanocratic,
very hard, massive, hyaline with fine hornblende augite, pink orthoclase
and plagioclase crystals, common feldspar phenocrysts up to granule in
size. High angle fractures infilled with calcite and occasionally chlorite
were also seen. The contact between the metasediments/volcanics and the
trachyte/diorite was dipping at 35 deg with a hole deviation of 14 deg.

6. SUMMARY AND CONCLUSIONS
Poeppels Corner was an exploration well drilled in the western flank
of the Eromanga Basin. The well was drilled in 33 days to a total
depth of 8500 ft using H bits at an average rate of penetration of
24.9 ft/hr.
No significant hydrocarbon indications were seen possibly due to the
lack of seal in possible "resevoirlt sections. Poeppels Corner No 1
was plugged and abandoned as a dry well.
