The main objective of the well was to prove hydrocarbons in the\r\nStatfjord Formation.

From 2605 to 2853 (Shetland Group) good oil shows were\r\nrecorded in sandstones and siltstones as well as in limestones. The Brent Group\r\nwas encountered at 2856 m and consisted of 12 m Etive Formation only. The Etive\r\nFormation was found to be oil bearing over the entire interval. The net pay was\r\n6.3 m with average log porosity of 19.1%. Also the 26 m thick Cook Formation\r\nwith top at 2920 m was oil bearing all through. Net pay here was 12.6 m with\r\naverage log porosity of 19.0%. No oil/water contacts could be established. The\r\nStatfjord Formation had weak shows in the top 10 m, but was found to be water\r\nbearing. RFT pressure recordings and sampling were recorded in 5 runs.\u00A0\r\nDifferent pressure regimes were proved for the Etive Formation, the Cook\r\nFormation and the Statfjord Group.\u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eFour cores were cut in the Etive and\r\nDrake Formations (2856 - 2909 m), two in the Cook and Amundsen/Burton\r\nformations (2923 - 2949 m) and one in the Statfjord Formation (2982 - 2990 m)",
