The primary objective of the well\r\nwas to verify the lateral and vertical distribution of sand within a thick\r\nVolgian sequence and to prove oil below 2690 m MSL in this sequence (deepest\r\noil in Volgian, well 33/9-8). The Brent Group was a secondary target.\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 33/9-14 was spudded with\r\nthe semi-submersible installation Deepsea Bergen and drilled to TD at 2982 m in\r\nthe Early Jurassic Drake Formation. There were signs of shallow gas from 408\r\n409 m, but the gas bearing sands created no problems. No significant problem\r\nwas encountered in the operations. The well was drilled with seawater/gel down\r\nto 414 m, with gypsum/polymer mud from 414 m to 2670 m, and with\r\ngel/lignosulphonate mud from 2670 m to TD.\u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eThe reservoir (interpreted as Kimmeridgian\r\nage Intra Draupne Formation Sandstone) came in as prognosed at 2674 m. The\r\noil/water contact was taken from the logs to be at 2747 m, while pressure\r\ngradients suggest the contact could be five meter higher up. Intermittent weak\r\nshows were described down to 2800 m, else no shows were described in the well. \u00A0The\r\nreservoir properties were very good with porosities up to 30 %. The Brent\r\nGroup, Ness Formation came in at 2777 m.
