No significant problems were\r\nencountered in the operations. The well was drilled water based with sea water\r\nand hi-vis pills down to 1083 m, gypsum/polymer mud from 1091 mud from 1091 m\r\nto 3783 m, and with Thermopol mud from 3783 m to TD.\u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eThe well penetrated Tertiary, Cretaceous\r\nand Jurassic rocks. The Middle Jurassic Brent Group was encountered at 3912.5\r\nm, unconformable below the Heather Formation. The Brent Group consisted of Ness\r\nFormation only. The underlying Dunlin Group came in with the Drake Formation at\r\n3941.5 m, and the Cook Formation at 3964.5 m. Gas and condensate was proven in\r\nthe Ness Formation and in the Cook formation down to top Burton Formation at\r\n4048 m. Pressure data clearly indicated no pressure communication between the\r\nNess and Cook Formation reservoirs. No gas-water contacts were established in\r\nthe well. Oil shows in traces of sandstones (direct and cut fluorescence) were\r\nrecorded over the interval 2030 m to 2100 m in the Lista and Våle formations\r\nand in the interval 2241 m to 2261 m in the Shetland Group. Cut fluorescence\r\nwas recorded also in shales from the Draupne and Heather formation.\u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eA total of 133.5 m core was cored in 13\r\ncores.
