The results from 34/10-37\r\nindicated a more complex fault pattern at the crest of the structure than\r\nexpected and it was decided to drill a sidetrack.\u003c/p\u003e\r\n\r\n\u003cp\u003eThe objective of the sidetrack, 34/10 -\r\n37 A, was to investigate the presence of a low angle fault at the crest of the\r\nD-prospect, which could explain the missing sections of the Tarbert Formation\r\nin 34/10-37. The well was planned to penetrate the top of the Brent Group at a\r\nhigher level than in 34/10-37 and terminate 50 m TVD below the oil-water\r\ncontact in the Brent Group.\u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eOperations and results\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eAppraisal well 34/10 - 37 A was kicked\r\noff through casing at 2049 m in well 34/10-37 on 22 February 1995 using the\r\nsemi-submersible installation Deepsea Bergen. It was drilled to TD at 2950 m in\r\nthe Middle Jurassic Ness Formation. No significant problems were reported from\r\nthe operations. The well was drilled with KCl/PAC mud from kick-off to TD.\u003c/p\u003e\r\n\r\n\u003cp\u003eIn addition to the formations encountered\r\nin 34/10-37 the well encountered the Rødby Formation, the Mime Formation and\r\nthe Draupne Formation. Well 34/10-37 A penetrated the top of the Brent Group 15\r\nm deeper than prognosed, but higher than in 34/10-37. An almost complete\r\nsequence of the Tarbert Formation was found in this well. The Brent Group\r\nproved to be hydrocarbon bearing with an "oil down to" at 2622 m TVD\r\nMSL. \u003c/p\u003e\r\n\r\n\u003cp\u003eFour conventional core were cut from 2664\r\nm to 2741 m in the Tarbert and Ness Formations.
