9 - Polecat appraisal. Targeting stratigraphic pinch-out in the J62 and J63 Upper Jurassic
Lower Buzzard Sandstone. The well proved 47.1 ft net pay in J63 from 9,694 ft TVDSS and
19.6 ft net pay in J62 from 9,909 ft TVDSS. DST 1 from 10,090–10,130 ft TVDSS flowed 906 bopd and 0.092 mmcfgpd (24/64" choke). DST 2 from 9,813–9875 ft TVDSS flowed 4,678 bopd and 0.386 mmcfgpd (40/64" choke). H2S values were 23,000–30,000 ppm and CO2 was 6-7%.
10 - Polecat appraisal. Targeting stratigraphic pinch-out in the J62 and J63 Upper Jurassic Lower Buzzard Sandstone. J62 Sandstone from 9,613 ft TVDSS had 231 ft
TVT gross section of low net/gross reservoir (0.15) with 3.5 ft net oil pay. Two oil samples containing 30,000 ppm H2S and four water samples were retrieved.
10Z - Polecat appraisal. Deviated NE from the surface location the Lower Buzzard at 10,056 ft was 155 ft deep to prognosis and water-wet; 73.5 ft net sand in clean, massive sands with an average porosity of 20.5%.
10Y - Polecat appraisal. Deviated SSW and up-dip from surface location to delineate the up-dip limit of the Lower Buzzard Sandstone. The J62 sandstone at 9,374 ft TVDSS was 232 ft TVT gross with 38 ft TVT of net reservoir and 4.5 ft net oil pay.
11 - Polecat appraisal drilled to test a depositional thick within the upper part of the Kimmeridge Clay. The Lower Buzzard Sandstone target was absent with no significant oil
shows.
