TEST DATA FROM THE DISCOVERY WELL (Skua-2):DST 2, 1,852-1,855 m,Recovered 30 bbls of formation water.DST 1, 2,332-2,336.5 m,Flowed 43.3 o API oil at 450 bbls/daythrough a 6.4 mm choke at 630 psi.Bathurst Island Group (Late Maastrichtian)Bathurst Island Group (Santonian)APPRAISAL AND DEVELOPMENT DRILLING :Skua-1 was drilled inside structural closure but intersected the reservoir below the oil/water contact andwas plugged and abandoned. Minor oil shows were recorded in swc’s shot at the Miocene/Eoceneunconformity and in tight Palaeocene limestones.Skua-2 intersected the western bounding fault of the structure at 2,338 mKB and did not penetrate acomplete reservoir section. The well was subsequently plugged and abandoned due to poor flow rates.A residual oil column was identified between 1,853 mKB and 1,859 mKB in a Late Maastrichtian sandin Skua-2. Testing (DST 2) indicated the sand was water saturated. The Santonian oil saturated sandtested by DST 1 in the Skua-2 well is juxtaposed against the Plover Formation reservoir across thewestern bounding fault. The unit is thought to be draining oil across the fault from the Plover Formationbut due to poor reservoir quality, the Santonian sand acts as a natural choke to flow.Skua-3 was initially drilled vertically to test a series of shallow, stacked closures. Below 1,488 mKB, thewell was drilled directionally to intersect deeper closures in an optimal position. The well intersected a44.4 mTVT hydrocarbon column between 2,286.3 mTVDSS and 2,330.7 mTVDSS (35.8 mTVT of netpay) and was suspended as a potential oil producer. Skua-3, drilled in a crestal position, was the firstwell to test the Plover Formation reservoir proper. DST 2, taken over the interval 2,376-2,381 m, flowedoil at 5,477 bbls/day and gas at 240,665 m 3 /day.Skua-4, located 1.8 km northeast of Skua-3, was cased and suspended as a future oil producer.Skua-5 was an appraisal well designed to test the northeasterly extent of the field. The well tested asmall, deeper and separate oil and gas accumulation which was not thought to economically producible.The well was plugged and abandoned.Skua-6 was drilled as a flank appraisal well. The well was plugged and abandoned after encountering aresidual oil column down to 2,368 mSS in the Early Jurassic section.Skua-7 was plugged and abandoned after the Operator was unable to run 30” surface casing. The wellwas redrilled as Skua-7A.Skua-7A was drilled as production well on the northern culmination of the field. The well intersected a29 m oil column (12.9 m net pay) but the oil/water contact was obscured by a shaley interval. Oil wasrecorded down to 2,333 mSS. Skua-7A also intersected a 1 m oil column overlain by gas in a thin sandwithin the Puffin Formation (1,930 – 1,932.5 mKB).Skua-8 was completed as a future producer after intersecting a 51 m gross hydrocarbon column (4 m gascolumn, 47 m oil column).Skua-9 intersected a 50 mTVT gross hydrocarbon column (41.9 mTVT net pay) before the drill stringbecame irretrievably stuck at 2,534 mKB. The well was plugged back and kicked off at 2,074 mKB asSkua-9ST-1.Skua-9ST-1 was completed as a future producer after intersecting a 53 mTVT hydrocarbon column(46.5 m oil column, 6.5 m gas column) between 2,280 mTVDSS and 2,333 mTVDSS.
