The Spring Gully field is located approximately 75 km northeast of Roma in southeast Queensland.It was anticipated that the wellbore would intersect 3 coal seams within the Bandanna Formation with the potential to produce coal seam gas - the CRB3, CRB2 and CRB1 seams. The CRB3 and CRB1 seams were intersected with the total net coal estimated at 3.53 metres.From 20 - 28 August 2008 a cavity completion operation was conducted to air drill the well to total depth, stimulate the coal seams via open hole cavitation, and install a 2-3/8" production string with progressive cavity pump.PAGE 2SPRING GULLY 83WELL COMPLETION REPORTGEOLOGICAL SAMPLESWireline LogsDateLog TypeIntervalContractorLogging Run 13/08/08Cement Bond Log4.0 - 589.8 mRTVauseLogging Run 222/08/08GR-Cal-Density510.0 - 710.0 mRTVauseLogging Run 3Full Hole CoresDateIntervalSizeCut (m)Recovered (m)NoneSidewall CoresDateIntervalSizeCut (m)Recovered (m)NoneMudloggingDateIntervalRate of ProgressGas LevelsNoneCutting SamplesDateIntervalLithologyNoneWELL TESTSDrill Stem TestingPressures (psig)DateIntervalFormationGas Flow RateFluid RecoveryInitial FlowInitial ShutInFinal FlowFinal Shut InNoneNoneNoneCavitation ResultsGas Flow Rates (mmscfd)Pressure (psig)Water Flow Rates (bwpd)Total Number of CavitationsTotal Injection Time (hrs)Initial0.241.71201344Final0.2794.499SURVEYSWell Location SurveyDateLatitudeLongitudeGround LevelEastingNorthing20/03/0925? 50' 58.25831" S149? 04' 17.40345" E345.38707 602.6277 139 344.353NoneDeviation SurveyPAGE 3SPRING GULLY 83WELL COMPLETION REPORTHole and Casing Schematic7-1/6" X 7" tubing head w/ 3-1/2" EUE tubing hanger w/ 2 X 3-1/8" gate valvesStratigraphic ColumnFormation tops were picked by Geoscientists from wireline log and ROP curve data.

The Spring Gully project and the neighbouring Fairview CSG field produce gas from the methane-rich coals of the Bandanna Formation. The Spring Gully & Fairview fields are situated on a regional north-south trending basement high known as the Comet Ridge.The Late Permian coals within the Comet Ridge were deposited during the thermal sag phase of the Bowen Basin’s tectonic history, when rapid regional subsidence allowed the basin-wide development of peat forming environments. The resulting Permian coals are laterally extensive and can be traced throughout the subsurface over much of the Spring Gully & Fairview fields. These coals are stratigraphically equivalent to the Rangal and Baralaba Coal Measures to the north and east respectively and are a very important source of coal seam gas throughout the Bowen Basin.Drilling within the Spring Gully tenures has established the presence of a relatively thin veneer of Early to Middle Jurassic sediments of the Surat Basin sequence unconformably overlying a variable thickness of Middle Triassic to Late Permian Bowen Basin sediments. The Jurassic strata, which include the Walloon Subgroup, Hutton Sandstone, Evergreen Formation, & Precipice Sandstone, dip regionally towards the south west into the depocentre of the Surat Basin; however tilting has been very minor. The Triassic and Permian strata of the underlying Bowen Basin sequence deepen much more rapidly towards the eastern edge of ATP 592P and into the Taroom Trough. These two sediment packages are separated by the Base Jurassic erosional unconformity, which corresponds to the base of the Precipice Sandstone. This unconformity truncates the Bandanna coals along the western edge of PL 195, PL 203, & PL 200.In a broad sense the dominant structural features of the Comet Ridge can be characterised by an episodic history of deformation, which has been driven by a compressive tectonic regime. Compression associated with foreland thrust loading during the Early to Middle Triassic was responsible for the closure of the Bowen Basin during the early Late Triassic and lead to uplift and erosion of the Bandanna Formation along the western margin of the Comet Ridge. Subsequent compressional folding and faulting in the Middle Cretaceous has accentuated earlier formed features and initiated an extended period of non-deposition and sub-areal erosion that continues today.PAGE 4SPRING GULLY 83WELL COMPLETION REPORTLOCATION MAPREFERENCESReverdito, D.PL204 SPRING GULLY 83 DRILLING PROGRAMME OVERVIEW, unpublished report prepared for Origin Energy CSG Limited.APPENDIX 1 - RIG #1 DAILY REPORTS359994-572DRILLING MORNING REPORT # 1Spring Gully 83Date:14 Apr 2008Well Site Representative:Damian DraheimRig Manager:Vern SmithReport Number:1Night Representative:Paul BawddenDrilling Company:Mitchell DrillingCorporationLatitude (South):25 ° 50 ' 58.32 "Longitude (East):149 ° 04 ' 18.10 "Geologist:Well DetailsCountry:AustraliaCurrent Hole Size:Casing OD:Original AFE:$ 1,046,794Field:Spring GullyMeasured Depth:10.00mCasing MD:Orig. & Supp. AFE:$ 1,046,794Rig:MDC Rig 141True Vertical Depth:0.00mCasing TVD:AFE Number:701 0133GL - AMSL:343.5m24 Hr Progress:0.0mTOL MD:Daily Cost:$ 95,088RT - GL:2.50mDays From Spud:Liner MD:Cum.
