The well was situated 5.0 kms north-east of Glimma 1 and 12.5 kms east of Ranger South 1.Python 1 lies at the eastern limit of the Tennaperra Trough, a sub-basin of the Nappamerri Trough. The exploration play to be tested involves the stratigraphic trapping of hydrocarbons within fluvial sands of the basal Patchawarra Formation. The Vc30- Vc45 interval comprises gas bearing sands in the nearby Stokes/Quasar area, and constitutes the primary objective of the Python prospect. The Python prospect encompasses an embayment into which a fluvial system has deposited thick sand development. Hydrocarbon migration was envisioned to be channelled to the head of the embayment along the sealing edge between the target sand package the upper shaley / coaly section of the Patchawarra Formation. An additional fault seal is required in the more down dip reaches of the embayment. Fault seal leakage is the key risk for the mid Patchawarra target. The greater Python trap has the potential for a very large accumulation of gas to be discovered, but a relatively low chance (5%) of success. If Python 1 is successful, several similar embayment style prospects along the southern flank of the Nappamerri Trough will have improved prospectivity and follow up potential.The primary target Patchawarra Formation was intersected 19’ H to prognosis and 594’ updip of Ranger South 1. The section comprised all the expected sandstone reservoirs (20-20, 25-10, 25-20, 30-30, 35-10). The sandstones were of fair quality and fair visual porosity. However poor gas readings were observed in the potential reservoirs, with typical gas levels within the sands only 10-20% of the interbedded coal seams. Log analysis determines the sandstones to be entirely water saturated. No gas pay could be ascribed to Python 1.Formation tops were generally intersected low to prognosis, except for the Early Permian formations, and ranged from 257’ L (Coorikiana Sandstone) to 60’ H (Murteree Shale). Formation thicknesses were generally within acceptable range limits to that prognosed. The Murteree Shale and Patchawarra Formation were thicker than prognosed by: 41’ (28%) and 97’ (16%) respectively. The Nappamerri Group and Roseneath Shale were 45’ (37%) and 65’ (23%) thinner than expected. All formation tops were significantly up dip (250’-600’) to Ranger South 1.The well reached a total depth of 7572’ (D) after penetrating 146’ into the Basement. Python 1 was plugged and abandoned on the 5th of August, 2006 with 7 plugs as follows: Plug 1: 7476’-7276’, Plug 2: 6419’-6219’, Plug 3: 5614’-5140’, Plug 4: 4556’-4166’, Plug 5: 3336’-3026’, Plug 6: 2638’-2338’, Plug 7: 33’ to Surface.Date: January, 2007.AUTHOR: S.

The exploration play to be tested involves the stratigraphic trapping of hydrocarbons within fluvial sands of the basal Patchawarra Formation. The Vc30-Vc45 interval comprises gas bearing sands in the nearby Stokes/Quasar area, and constitutes the primary objective of the Python prospect. The Python prospect encompasses an embayment into which a fluvial system has deposited thick sand development. In plan view the prospect has a broad V-shape, comprising a large stratigraphic on-lap trap covering some 5400 acres in the proximal reaches to the east, while its two distal extremities rely on fault dependent closure to the south and west. Hydrocarbon migration was envisioned to be channelled to the head of the embayment along the sealing edge between the target sand package the upper shaley / coaly section of the Patchawarra Formation. An additional fault seal is required in the more down dip reaches of the embayment. Fault seal leakage is the key risk for the mid Patchawarra target. The greater Python trap has the potential for a very large accumulation of gas to be discovered, but a relatively low chance (5%) of success.

Samples were collected, washed and described at 10’ and 20’ intervals from 3960’ to 6850’ and at 10’ intervals from 6850’ to 7572’ (T.D).A brief summary of the section penetrated in Python 1 (with associated depositional environments) is found below. For more detailed lithological descriptions refer to Appendix Ia.Total depth for Python 1 was reached at 7572’ (-7165.6’), after penetrating 146’ into the BASEMENT (Pre-Permian). The Basement consists of predominantly meta-sandstone interbedded with minor meta-siltstone. The meta-sandstone is clear to translucent, fine to predominately medium grained, angular to sub-angular and conchoidal grain fractures, moderately well cemented with silica, with very poor visual porosity. The meta-siltstone is medium to dark grey, silvery grey to brownish grey, very finely arenaceous, siliceous, micromicaceous, moderately hard to brittle.The PATCHAWARRA FORMATION (Early Permian) unconformably overlies the Basement. The well developed section consists of a repetitive sequence of siltstone with moderately developed coal seams and moderately to well developed sandstone cycles. The sedimentary sequence is indicative of a low to moderate energy, back swamp, and mixed load fluvial environments of deposition. The well developed sandstones are indicative of a moderate energy, meandering fluvial environment of deposition.The MURTEREE SHALE (Early Permian) consists of a thick siltstone sequence deposited in a lacustrine environment. The siltstone is dark grey to black, dominantly argillaceous, carbonaceous and slightly micromicaceous in parts. It conformably overlies the Patchawarra Formation and marks the peak of a basin wide non-marine transgression.The EPSILON FORMATION (Early Permian) conformably overlies the Murteree Shale. The sequence comprises occasional thin coal seams, thick siltstone with a moderately developed fluvial sandstone at the top and base of the sequence. This is indicative of a fluvial/deltaic environment of deposition.The ROSENEATH SHALE (Early Permian) comprises a thick siltstone sequence deposited in a lacustrine environment. The siltstone is dark grey, argillaceous, slightly carbonaceous and micromicaceous in parts. It conformably overlies the Epsilon Formation and heralds an extensive non-marine transgression.The DARALINGIE FORMATION (Late Permian) conformably overlies the Roseneath Shale. The sequence comprises a truncated section of siltstone with fluvial-deltaic sandstone. The section displays a fining upwards character in a gross sense. Siltstone becomes dominant towards the top of the sequence, indicating a gradual transition to a lower energy, floodplain/deltaic environment.A major structural and erosional episode followed this deposition resulting in the TOOLACHEE FORMATION (Late Permian) unconformably overlying the Daralingie Formation. The sequence comprises well-developed, fine to medium grained channel sandstones with interbedded overbank siltstone and moderately developed coal in a cyclical fashion. Other less well developed, coarsening upward sandstones are indicative of fluvial-lacustrine environment of deposition. The overall style of deposition is typical of moderate energy, meandering fluvial environment with brief periods indicative of a lower energy, fluvial-deltaic environment of deposition.The NAPPAMERRI GROUP (Late Permian to Middle Triassic) conformably overlies the Toolachee Formation and represents the final phase of sedimentation in the Cooper Basin. It is dominated by light grey arenaceous siltstone with poorly developed interbedded sandstone. The sequence is representative of a lacustrine to oxidised fluvial/floodplain environment of deposition with minor fluvial episodes.During the middle to late Triassic period regional uplift and erosion coincided with local reactivation of Permian fault trends. The resultant erosional activity was greater over the structurally high trends and an essentially peneplained surface developed. Major epeirogenic down warping during the Early Jurassic initiated the development of the Eromanga Basin.The HUTTON SANDSTONE (Mid Jurassic) unconformably overlies the Nappamerri Group. The sandstone was deposited in a high energy braided fluvial environment, with occasional (and discontinuous) overbank siltstones. Sandstones are in general clear to translucent, off white, fine to coarse grained, with weak to moderately strong siliceous cement, trace to rare kaolinitic matrix, and fair to poor inferred and visual porosity. The siltstones are medium grey, medium to very dark brown grey, argillaceous to very finely arenaceous, micromicaceous in part, with occasional to common carbonaceous inclusions.The BIRKHEAD FORMATION (Mid to Late Jurassic) conformably overlies the Hutton Sandstone and was deposited in the lower energy conditions of suspended load fluvial to lacustrine environment of deposition. The section consists dominantly of siltstone with minor sandstone interbeds. The siltstones are medium grey to medium grey brown, argillaceous to very finely arenaceous in part and locally carbonaceous. The sandstones are off white to pale grey, very fine to fine grained, with moderately strong siliceous cement, minor kaolintic matrix, trace lithics, and very poor visual porosity.The NAMUR SANDSTONE MEMBER of the MOOGA FORMATION (Late Jurassic to Early Cretaceous) conformably overlies the Birkhead Formation and consists of predominantly sandstone with interbedded, moderately to poorly developed siltstone within the upper half of the sequence. The sandstone is generally fine to medium grained. The member is sequence of stacked channel sandstones deposited under medium to high energy braided fluvial conditions, punctuated with periods of lower energy overbank to floodplain siltstone deposition, particularly towards the upper sections..The upper section of the Mooga Formation is the MURTA MEMBER (Early Cretaceous) is dominantly a siltstone sequence interbedded with variably developed sandstone. Basally the unit consists of siltstone grading up into a sequence of interbedded siltstone and sandstone. This is consistent with a lacustrine to deltaic environment of deposition concurrent with a gradual marine transgression.Deposition of the CADNA-OWIE FORMATION (Early Cretaceous) represents a transitional period during the onset of a regional marine transgression. The majority of the sequence consists of arenaceous siltstone with minor limestone, indicative of a distal deltaic to paralic environment of deposition. This grades up to a fine to medium grained calcareous sandstone, indicative of a shallow marine to shoreline depositional environment.The BULLDOG SHALE (Early Cretaceous) consists of a massive sequence of siltstone/shale with minor interbedded limestone and calcareous sandstone. It represents a continuation of shallow to moderately deep open marine deposition and conformably overlies the Cadna-Owie Formation. Glauconite is common in the basal sandstones and siltstones with disseminated pyrite dominates within the top half of the sequence, indicating a trend towards reducing conditions during moderately deep water deposition at that time.The COORIKIANA SANDSTONE (Early Cretaceous) conformably overlies the Bulldog Shale and is a sequence thinly bedded sandstone and siltstone. The sandstone is fine grained, glauconitic and calcareous sandstone. The sequence is considered to be a regressive marine, shore-face deposit that accumulated in response to a mild fall in sea level. The deposit is relatively thin, but is extensive over a large area of the southern and western Eromanga Basin.The OODNADATTA FORMATION (Early Cretaceous) conformably overlies the Coorikiana Sandstone and consists of massive siltstone and claystone with rare sandy interbeds. The sediments are indicative of a relatively low energy, shallow marine environment of deposition.The MACKUNDA FORMATION (Late Cretaceous) conformably overlies the Oodnadatta Formation and comprises interbedded siltstone and minor claystone with poorly to moderately developed calcareous sandstone. The sandstone is more prominent in the top half of the sequence. The sediments indicate deposition within a paralic to marginal marine environment.The WINTON FORMATION (Late Cretaceous) conformably overlies the Mackunda Formation and consists of deposits from a variety of depositional environments. The basal section comprises interbedded siltstone and thin coal seams with minor sandstone, which suggests a low energy fluvial to swamp-like environment of deposition. This is overlain by predominantly siltstone with scarce to sometimes common fine grained sandstone interbeds. The presence of glauconite within this section indicates a shallow marine to paralic environment of deposition. A gradual dominance of non-marine environments occurs towards the top of the unit, alternating between low and medium energy fluvial regimes. Surficial deposits consisted of coarse grained aeolian sands with common interbedded flood plain claystone.For further details concerning the formations encountered in Python 1, refer to Appendix Ia of this report.Stratigraphic Prognosis (after Well Proposal)Python 1 as drilled as a vertical gas exploration well in ATP 259P, Queensland.

Formation tops were generally intersected low to prognosis, except for the Early Permian formations, and ranged from 257’ L (Coorikiana Sandstone) to 60’ H (Murteree Shale). Formation thicknesses were generally within acceptable range limits to that prognosed. The Murteree Shale and Patchawarra Formation were thicker than prognosed by: 41’ (28%) and 97’ (16%) respectively. The Nappamerri Group and Roseneath Shale were 45’ (37%) and 65’ (23%) thinner than expected. All formation tops were well up dip (250’-600’) relative to Ranger South 1.Hydrocarbon Summary (Logger’s Depths)Total gas was recorded from the surface to 7572’ T.D (Logger Extrapolated) using an FID total gas detector. One unit of gas is equal to 200 ppm methane equivalent. Chromatographic analysis was determined using an FID chromatograph and these values are quoted as percentages (C1 - C5). All samples were checked for oil shows using ultraviolet fluorescence.Surface to top Cadna-owie FormationTraces of gas were first recorded from 750’, within the Winton Formation. The gas was composed entirely of methane, from trace to 1 U (100/tr), throughout the remainder of the Winton section. Within the Mackunda, Oodnadatta Formation, Coorikiana Sandstone and Bulldog Shale, gas levels ranged between 0.5 U and 4 U (95/4/1), averaging 1.5 (100/tr). No hydrocarbon fluorescence was observed in any of the above formations.Cadna-owie Formation to Birkhead FormationThe Cadna-Owie Formation comprised finely interbedded calcareous sandstone and siltstone. The section displayed gas levels of 0.5-3 U (93/4/3) with no hydrocarbon fluorescence. Total gas within the underlying Murta Member of the Mooga Formation ranged from 1.5 U (100/tr) to 6 U (93/4/3). The Namur Sandstone Member comprised massive sandstone with minor siltstone and exhibits gas levels ranging from 1.5 U (98/2) to 7 U (90/7/3/tr) towards the base of the section. No hydrocarbon fluorescence was observed within this sequence.Birkhead Formation to Toolachee FormationThe Birkhead Formation is predominantly siltstone, with fine grained sandstone, particularly towards the base of the unit. Gas levels ranged from 5 U (87/8/4/1) at the top of the unit, decreasing to 3 U (84/8/4/4) at the base of the section. The underlying Hutton Sandstone comprised massive sandstone and exhibits gas levels ranging from 1.5 U (100/-) to 6 U (89/8/3/tr). The Nappamerri Group comprised a truncated sequence of predominantly siltstone with finely interbedded sandstone. Gas levels ranged from 2 to 6 U (84/6/4/6) within the section. No hydrocarbon fluorescence was observed within this sequence.Toolachee Formation to Patchawarra FormationThe Toolachee Formation comprised a thick section of interbedded siltstone, fluvial sandstones and common coal seams. Siltstones produced background gas levels of 10-20 U (79/14/6/1), with coal peaks producing gas peaks of 30-200 U (94/5/1). The Toolachee section comprised seven main fluvial sandstone units. They displayed poor gas responses from 25-40 U (86/12/2). Approximately 1’ of residual net gas pay (Porosity: 12.1%, Sw: 67%), was ascribed to the section, but is considered to be water saturated. The underlying Daralingie Formation comprised predominantly siltstone with moderately developed basal sandstone. Gas levels were fairly consistent and ranged from 15-45 U (85/12/3/tr). The basal sandstone was water saturated and exhibited only 7-9 U (81/15/4/tr). The underlying Roseneath Shale comprised massive siltstone with gas levels of 4-10 U (83/13/4) and essentially acts as a regional seal to the underlying Epsilon Formation.The Epsilon Formation comprised a sequence of siltstone with moderately developed sandstone and occasional coal seams. Siltstones produced background gas levels of 4-11 U (79/15/6), with coal peaks producing gas peaks of 26-42 U (88/10/2). The Epsilon section comprised two moderately developed fluvial sandstone units at the top and base of the sequence. They both displayed poor gas responses of 4-10 U (77/17/6). Log analysis ascribes water saturation to both sands. The underlying Murteree Shale comprised massive siltstone with gas levels of 7-29 U (85/12/3) and essentially acts as a regional seal to the underlying Patchawarra Formation.Patchawarra FormationThe reservoir sandstones of the Patchawarra Formation comprised the primary gas objectives at Python 1. A minimum of 25’ of net gas pay was predicted for the Patchawarra sandstones. The Patchawarra Formation was intersected 19’ high to prognosis and 594’ updip of Ranger South 1. It comprises a cyclical sequence of siltstone with moderately developed sandstone and common coal seams. Siltstones produced background gas levels of 10-28 U (83/14/3), with coal peaks producing gas peaks of 30-190 U (95/4/1/tr). The Patchawarra section comprised thirteen significant fluvial sandstone units. They all displayed poor gas responses. Log analysis ascribes 2.2’ of minor scattered gas pay, (Porosity: 12.8%, Sw: 64%), within mid to lower Patchawarra sands. The sands are all effectively water saturated.No FMT survey or DSTs were conducted at Python 1 due to the lack of gas saturation.BasementThe Basement comprised meta-sandstone with minor interbedded meta-siltstone. The section displayed gas levels of 15-50 U (87/11/2/tr). Python 1 was drilled to a T.D. of 7572’, 146’ into the Basement.SUMMARYPython 1 was drilled as a gas exploration wildcat well in the Total 66 Block, ATP 259P, Queensland. The well was situated 5.0 kms north-east of Glimma 1 and 12.5 kms east of Ranger South 1.Python 1 lies at the eastern limit of the Tennaperra Trough, a sub basin to the Nappamerri Trough. The exploration play to be tested involves the stratigraphic trapping of hydrocarbons within fluvial sands of the basal Patchawarra Formation. The Vc30-Vc45 interval comprises gas bearing sands in the nearby Stokes/Quasar area, and constitutes the primary objective of the Python prospect. The Python prospect encompasses an embayment into which a fluvial system has deposited thick sand development. Hydrocarbon migration was envisioned to be channelled to the head of the embayment along the sealing edge between the target sand package the upper shaley / coaly section of the Patchawarra Formation. An additional fault seal is required in the more down dip reaches of the embayment. Fault seal leakage is the key risk for the mid Patchawarra target. The greater Python trap has the potential for a very large accumulation of gas to be discovered, but a relatively low chance (5%) of success. If Python 1 is successful, several similar embayment style prospects along the southern flank of the Nappamerri Trough will have improved prospectivity and follow up potential.The primary target Patchawarra Formation was intersected 19’ H to prognosis and 594’ updip of Ranger South 1. The section comprised all the expected sandstone reservoirs (20-20, 25-10, 25-20, 30-30, 35-10). The sandstones were of fair quality and visual porosity, however gas response was poor for the reservoirs, with typical gas levels within the sands only 10-20% of that produced by the interbedded coal seams. Log analysis determines the sandstones to be entirely water saturated. No gas pay could be ascribed to Python 1. Lack of fault seals would be the likely cause of the failure of gas charge within the Patchawarra sandstone reservoirs.Formation tops were generally intersected low to prognosis, except for the Early Permian formations, and ranged from 257’ L (Coorikiana Sandstone) to 60’ H (Murteree Shale). Formation thicknesses were generally within acceptable range limits to that prognosed. The Murteree Shale and Patchawarra Formation were thicker than prognosed by: 41’ (28%) and 97’ (16%) respectively. The Nappamerri Group and Roseneath Shale were 45’ (37%) and 65’ (23%) thinner than expected. All formation tops were well up dip (250’-600’) relative to Ranger South 1.The well reached a total depth of 7572’ (D), 146’ into the Basement and was plugged and abandoned on the 5th of August, 2006.REFERENCESPlummer P., Santos Ltd., 2006.Python 1 Well Proposal, Santos Ltd.

A 9?” surface hole was drilled to 2549’ where 7?” casing was set. A 6?” hole was then drilled with KCl Polymer mud to TD. Wireline logging was carried out as described below.Python 1 wire-line logs were analysed over the Jurassic and Permian Formations (4076’ – 7572’ MDRT), with very small amount of conventional pay identified in the Toolachee and Patchawarra Formations (close to cut-offs).Python 1 has been abandoned as a dry hole.Unless otherwise specified, all depths mentioned below are wireline depths referenced to the drill floor.Pay SummaryFormationHIP (ft)HIP Av.Por (%)HIP Av.

Run 1 and 2 were merged for final log presentation.Data acquired were of average quality – MLL was affected by borehole rugosity and washouts.Log ProcessingThe GR was corrected for environmental effects such as mud-weight and borehole size.The DLL was corrected for borehole, shoulder bed effects and formation invasion. (See Appendices 1).A bad hole flag was created which was determined using the caliper.Rw was derived from offset wells.Python 1 was evaluated using the Determin module of Geolog.Deterministic Method and ProcedurePermian coal sequences were identified, primarily, from the sonic responses with some reference to the micro-resistivity caliper responses. The initial coal flag is created using an evaluate statement and edited where necessary.Where only GR available, a shale volume curve was derived from the borehole and environmentally corrected GR responses (GR_COR). The matrix and shale GR values were determined using standard cross plotting techniques.With only sonic available, total porosity over the Permian formations has been calculated from the sonic responses using the Overton equation.For the Jurassic Formations with no density-neutron, the sonic porosity is calculated using the Geolog Sonic Porosity module and the Wyllie time average equation. Only the total porosity from this module is used.Effective porosity was calculated using the Geolog PHIE module using the above total porosity and GR_COR as inputs.Both m and n were calculated as variable.Water saturations in the Permian formations as well as the clean sandstone Jurassic formations were calculated using a pseudo-Archie equation.See Appendices 1 for further information on equations used in this method.Following are tabulations of the analysis parameters utilised in each of the interpreted intervals in the well.ParameterCadna-Owie FmMurta MemberNambur SstBirkhead FmHutton SstRw (ohmm) @ 75?F1.51.51.51.51.5a11111mVariableVariableVariableVariableVariablenVariableVariableVariableVariableVariableGRma (API)2020202020GRsh (API)130170143143162DTsh (us/ft)10097819480Porosity methodSonic-WhyliieSonic-WhyliieSonic-WhyliieSonic-WhyliieSonic-WhyliieSw equationArchieArchieArchieArchieArchieParameterNapamerri GroupToolachee FmDaralingie FmRoseneath ShaleRw (ohmm) @ 75?F1.51.51.51.5a1111mVariableVariableVariableVariablenVariableVariableVariableVariableGRma (API)20202020GRsh (API)195180192192DTsh (us/ft)77867875Porosity methodSonic-OvertonSonic-OvertonSonic-OvertonSonic-OvertonSw equationArchieArchieArchieArchieParameterEpsilon FmMurteree ShalePatchawarra FmBasementRw (ohmm) @ 75?F1.51.51.51.5a1111mVariableVariableVariableVariablenVariableVariableVariableVariableGRma (API)20202020GRsh (API)194201206224DTsh (us/ft)84767761Porosity methodSonic-OvertonSonic-OvertonSonic-OvertonSonic-OvertonSw equationArchieArchieArchieArchiePay SummaryThe definitions of ‘sand’, ‘conventional pay’, and ‘non-conventional (HIP) pay’ as utilised in this analysis, are as follows:Gross sand is defined as any interval where PHIE > 2%.Conventional net sand is defined as any interval where PHIE > 8%.Conventional pay is any interval where PHIE > 8% and Sw < 70%.HIP net sand is defined as any interval where PHIE > 4%.HIP pay is any interval where PHIE > 4% and Sw < 70%Following are tabulations of Permian aged HIP intervals interpreted in the Python 1 well.FormationInterval (ft)Gross Sand (ft)HIPSand (ft)Avg PHIs (%)HIPPay (ft)Avg PHIp (%)Avg Sw (%)Toolachee Fm5564 – 6050179.5122.89.11.012.167Patchawarra Fm6716 – 7426322.2281.89.72.212.864Following are tabulations of Permian aged conventional pay intervals interpreted in the Python 1 well.FormationInterval (ft)Gross Sand (ft)Net Sand (ft)Avg PHIs (%)Net Pay (ft)Avg PHIp (%)Avg Sw (%)Toolachee Fm5564 – 6050179.56512.21.012.167Patchawarra Fm6716 – 7426322.2203.811.02.212.864ConclusionsPython 1 log analysis has identified 1.0’ of conventional pay in the Toolachee Fm (average porosity of 12.1% and average Sw of 67%) and 2.2’ of conventional pay in the Patchawarra Fm (average porosity of 12.8% and average Sw of 64%).Python 1 log analysis has identified 1.0’ of HIP pay in the Toolachee Fm (average porosity of 12.1% and average Sw of 67%) and 2.2’ of conventional pay in the Patchawarra Fm (average porosity of 12.8% and average Sw of 64%).Python 1 has been abandoned as a dry well.Python 1 analysis results have been graphically presented in the well evaluation summary (WES) plot - /data/wessa/python1_06208.wesAPPENDICES 1Interpretation Procedures for Deterministic MethodEnvironmental corrections for the GR, neutron and density were applied using the Geolog modules specific to the service company and tool.If a ‘true’ shale is present in the well (eg Roseneath or Murteree Shale) a density correction is applied that calibrates the density in a 6 ?” hole to the density in an 8 ?” hole.Borehole corrections for the Dual Laterolog curves were applied.These are ratios used to emulate the algorithms supplied by the service companies.The borehole corrected deep resistivity curve was further corrected for shoulder effects as per service company chart books and algorithms..The invasion corrected RT was derived using the following relationship:RT= (1.8*RDC-0.75*RS_BC)Where:RT = True formational resistivityRDC = Deep resistivity response borehole and shoulder bed corrected.RS_BC = Shallow resistivity response borehole corrected.A bad hole flag was created. If density was available the bad hole was determined using the zcor, otherwise the caliper was used. Standard cross plotting techniques were used to determine the cut off values for bad hole.Where X-Y density was run, a ZDENXY curve was created by using the best quality density curve depending on the zcor for each axis. It is the ZDENXY curve that is used for the the evaluation.Where necessary, the sonic log had cycle skips removed.Permian coal sequences, as well as Permian and Jurassic carbonaceous shales, were identified, primarily, from the sonic responses with some reference to the micro-resistivity caliper responses. The initial coal flag is created using an evaluate statement and edited where necessary.If density-neutron was available, the volume of shale was calculated using the appropriate Geolog module. The input parameters for the matrix and shale points were derived from standard cross plots. The environmentally corrected curves were used for this calculation.Where only GR available, a shale volume curve was derived from the borehole and environmentally corrected GR responses (GR_COR) using the following relationship.Vsh = (GR – GRma)/(GRsh – GRma)Where:Vsh = volume of shaleGR = measured gamma ray responseGRma = GR response in 100% clean matrixGRsh = GR response in 100% shaleThe matrix and shale GR values were determined using standard cross plotting techniques.If density-neutron logs were available, total porosity was calculated using the Geolog Chart Look Up module which is very similar to the Bateman-Konen method of porosity determination. The values for the input parameters were picked from standard density-neutron cross plots. Although this module outputs an effective porosity, this is not used for the Permian and only the PHIT is taken from this module.If only sonic is available, total porosity over the Permian formations in South Australia has been calculated from the sonic responses using the Overton equation as follows.PHIO = (DT – DTg) / (DTfl – DTg)Where:DT = Measured sonic response timeDTfl = empirically derived, location and formation specific, relationship which has been shale and gas correctedDTg = Grain sonic travel time (usually assumes a value of 55.5, which is a typical sonic travel time for quartz)For Queensland wells and the Jurassic Formations with no density-neutron, the sonic porosity is calculated using the Geolog Sonic Porosity module and the Wyllie time average equation. The Wyllie equation is essentially identical to the Overton equation, itemised above, but is not empirically derived or formation specific. Only the total porosity from this module is used.For Jurassic formations, the effective porosity from the density-neutron Chart Look up module is used.For the total porosity calculated from either density-neutron or sonic, a shale corrected total porosity (PHIE to be used in the Archie equation) was calculated as follows:if Vsh < VshSt………………..PHIE = PHITelseif VshSt < Vsh < VshCO…PHIE = a proportional percentile correctionfrom PHIT to (PHIT – (Vsh * PHIsh))elseif Vsh > VshCO …………PHIE = PHIT - (Vsh * PHIsh) Where:VshSt =The start of the sliding scale Vsh correction.VshCO =Shale volume cut-off.Vsh = Shale volume.PHIT = Total porosity.PHIsh = Apparent shale porosity.A Cooper Basin specific variable cementation exponent “m” was calculated using the relationship obtained from overburden corrected SCAL “m” measurements, cross-plotted against overburden corrected core porosity. This relationship was determined as:MEXP = (-0.2413 * Log10 PHIE) +2.4657Following the Petrophysics Audit, it was recommended that a pseudo saturation exponent “n” other than the default of 2 be used in the Archie equation. This is to take into account the impact of fresh water on “n” and also the impact of micro-porosity inherent in shaly sandstones. It is postulated that shale intergranular micro-porosity increases the surface area (conductivity) of the rock, and therefore “n” needs to be adjusted to compensate for the extra conductivity in shaly sandstones. Special core analysis data from Queensland and published journal papers form the basis of the relationship:Clean sand “n” =1.85Shaly sand “n” = 1.50Shaly sand is defined where the shale volume is greater than a cut-off of 60%. Saturation exponent is gradational between the two end-points above.Water saturations in the Permian formations as well as the clean sandstone Jurassic formations were calculated using a pseudo-Archie equation.aRwn? mRtSW ?where:Rw =Resistivity of formation water at formation temperature.RT =True resistivity, i.e. resistivity of the non-invaded reservoir (i.e.LLD corrected for borehole, invasion and resistive shoulder beds).PHIT= Input as shale corrected PHIE (derived above). a =Porosity coefficient (default = 1).m =Cementation factor or exponent from the variable “m” relationship. n =Saturation exponent from the “n” relationship derived above.Rwen? mRtFor the ‘shaley-sand’ formations (eg Murta and McKinlay) the Juhasz method of determining water saturation was used. It uses log-derived estimates of BQv as inputs to the Waxman-Smits equation for water saturation. The Waxman-Smits equation can be written in the form:SW ?where:1Rwe? 1 ? BQv RwSwtRw= formation water resistivity.Rwe= equivalent bulk water resistivity.B= equivalent conductance of the exchange cations.Qv= cation exchange capacity per unit total pore volume. Swt= total water saturation.The value of BQv is required to determine water saturation. The required special core analysis to determine B and Qv is not available, therefore the Juhasz method allows the estimation of BQv from logs.The Juhasz method involves constructing a cross-plot of RPD (relative porosity difference) and Cwa (apparent formation water conductivity).where: ? NRPD ? ?? N= neutron porosity.? ?T ??T?T = total porosity, which is best represented by density porosity.andCwa ?1mRT ? ?Twhere: RT= true resistivity.?= total porosity.m = determined from a Pickett plot (or other suitable methods).The slope of the line through the data is equal to BC in the equation below. Using the value of the slope (BC) and the calculated RPD, an estimate of BQv can then be made.BQv ? BC ? ?? N ? ?T ? ? BC ? RPD?TUsing this estimate of BQv, water saturation is determined via the Juhasz method.Juhasz water saturation can be run with either of two Geolog modules. One of these modules used the slope of the above data, while the other used the true resistivity of shale as an input.If calculated, permeability was determined using either a field specific porosity-permeability transform (only available for some South Australian fields) or the Geolog Coates Free Fluid Index module. The parameters in the Coates module were altered to fit the permeability curve to any mobility permeability points.APPENDIX IV (b): FMT PRESSURE SURVEY DATANo FMT Survey was conducted at Python 1.APPENDIX IV(c): FIELD ELECTRIC LOG REPORTSANTOS LIMITEDFIELD ELECTRIC LOG REPORTWell:PYTHON 1Geologist:S.OSTLERLogging EngineerI.SIREGARSuite no.1Date logged:02/08/06 -03/08/06Driller's depth7572’Loggers depth:7572’Arrived on site:31/07/06: (17.00)Truck no.4231Actual log time:14 hrs.Lost time logger-Total time:14 hrs.Lost time other:-Type of logGR-RESISTIVITYGR-SONICTime circ. stop16.30 02/08/0616.30 02/08/06Time tool rig up22.15 02/08/0606.00 03/08/06Time tool run in hole23.0006.40Time tools on bottom01.10 03/08/0608.50Time tools at surface05.0511.15Time tool rigged down06.0012.15 03/08/06CommentsTotal time7 hrs 45 mins6 hrs 15 minsType of logFromToBHTTime since mentsSuite 1/Run 1GR-7514’13.3’252°F @ 7478’8 hrs 45 mins.MLL-4 ARM CAL7569’2539’DLL-7549’2539’SP7493’2539’Suite 1/Run 2GR-7527’2539’264°F @ 7505’16 hrs 50 mins.DAC-7548’2539’WFT7560’5450’monopoleMUD SYSTEM: 3.5% KCl-PolymerHOLE CONDITIONS:WEIGHT:9.6 ppgFair.Rmf: 0.055 @ 70.5°FRm: 0.059 @ 70.0°F7.625" Casing shoe: 2538.7’ (D) & (L)Rmc: 0.093 @ 72.2 °FWELLSITE LOG QUALITY CONTROL CHECKSLOG ORDER FORMXMUD SAMPLE RESISTIVITYXTOOL NO. / CODE CHECKXOFFSET WELL DATAXCABLE DATA CARDXLOG SEQUENCE CONFIRMED.XLOG TYPEDACGRCALDLLMLLCNZDLREMARKSCasing check57 ms6.969”Scale checkXXXXXDepth Casing TotalXXXXCalibration OKXXXXXRepeatXXXXXLogging speedXXXXXOffset well repeatabilityXXXXXNoisy / Missing dataXXXXXCurve/Log Depth MatchedXXXXXRmXXLLS / LLD / CheckXXPERF / RHOB CheckLog header / tailXXXXXPrint qualityXXXXXCOMMENTS: Original grand-slam run was split into two runs: GR-DLL-MLL-4CAL-SP and GR-DAC-WFT due to lack of Basement rat hole (as interpreted from drilling results).APPENDIX V: GEOTHERMAL GRADIENTA Temperature Gradient of 2.75?F/100’ and a BHT of 278?F was calculated for Python 1.MaxRecorded Temp (degF)Depth Recorded (ft)Time SinceCirculation.
