Its primary objective was to test possible\r\nhydrocarbon accumulations in Middle and Early Jurassic sandstones on the Beta\r\nProspect at an antiform structure in the southeastern part of the block.\r\nSecondary objectives were Early Jurassic and Triassic sandstones, in addition\r\nto sands within the Coal Beds. Prognosed TD was at 4380 m in the Jurassic coal\r\nsequence, or in Middle Jurassic sandstones at 3902 m.\u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eOperations and results\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eWell 6506/12-2was spudded with the\r\nsemi-submersible installation Ross Isle on 12 February 1985 and drilled to TD\r\nat 955 m in Pliocene sediments (Nordland Group). A pilot hole was drilled to\r\n955 m and logs were run. Shallow gas was detected on log readings at 572 m, and\r\ngas peaks of 6.9% at 573 m and 6% at 580 m confirmed this observation. Water\r\nflow and lost circulation caused problems, but was stabilised with LCM pills.\r\nThe well was drilled with seawater and pre-hydrated bentonite. \u003c/p\u003e\r\n\r\n\u003cp\u003eProblems with a wear bushing caused the\r\nabandonment of the well on 28 February 1985.
