The objectives\r\nwere to confirm the presence of mobile hydrocarbons and the pressure regime in\r\nthe SI segment (Statfjord Formation); to confirm the absence of free gas cap\r\nand also pressure regime and fluid composition in the NI segment (BrentGroup);\r\nto improve stratigraphic control of base Cretaceous, the A-Central Fault, top\r\nStatfjord and top Lunde; and to characterise the Lunde B/C aquifer and pressure\r\nregime.\u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cb\u003e\u003cspan lang=EN-GB\u003eOperations and results\u003c/span\u003e\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eAppraisal well 34/8-10 S was spudded with\r\nthe semi-submersible installation Polar Pioneer on 28 September 1993 and\r\ndrilled to TD at 3470 m (3316 m TVD) in the Late Triassic Lunde Formation. The\r\nwell was drilled with an angle of 37 degrees through the reservoir to achieve\r\nthe objectives.

The Brent Group was penetrated at 2879.5 m in a heavily faulted\r\narea. It was represented by the Rannoch Formation from 2879.5 to 2885 m and by\r\nEtive Formation from 2888 to 2896.5 m with a fault slice identified as Drake\r\nFormation in between (2885-2888 m). A gross reservoir thickness of 14 m was\r\ndefined, giving a net pay of 10 m. The pressure in the Brent Group was found to\r\nbe higher than previously documented, and in addition the oil was of a lighter\r\ncomposition. No free gas cap was found in the Brent sandstones.\u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eThe Amundsen Sandstone was not expected\r\nto be penetrated as the well was planned to cut the A-Central fault ve",
