The\r\nwork obligation for Block 35/11 included three exploration wells to be drilled\r\nto 4000 metres or to Triassic sediments, one of which must test an Early\r\nCretaceous stratigraphic play. The first of these wells, 35/11-1, was drilled\r\nin 1984 to a depth of 3361 m in rocks of Triassic age. The primary objective of\r\nthat well was to assess the hydrocarbon potential of the Middle to Upper\r\nJurassic sands in the "A" structure. No hydrocarbons were present in\r\nany of the objectives although good quality Brent sands were encountered. The second\r\nwell to be drilled on the block was 35/11-2. It was designed primarily to test\r\nan Early Cretaceous stratigraphic play, interpreted seismically as a fan\r\ndevelopment with a 130 km3 closure, and reservoir thickness of 270 m. A\r\nsecondary objective was the "B" structure at Brent level. \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\u003eWildcat well 35/11-2 was spudded with the\r\nsemi-submersible rig Treasure Scout on 20 July 1987 and drilled to TD at 4025 m\r\nin Early Jurassic rocks. The hole was drilled to setting depth for 20"\r\ncasing without a riser. MWD was used, but the resistivity unit was destroyed\r\nafter few meters. Conventional logs did not get past 760 m, and while\r\nattempting this; there was an intrusion of formation fluid into the hole. There\r\nwas no sign of shallow gas, and heavier mud was used. The hole was opened to\r\n26" without logging below 760 m. The reason for the problems around 760 m\r\nwas probably washed-out zones. When preparing the setting of 20"casing,\r\nfluid was again flowing into the hole, and the mud weight was increased.\r\nFurther dril",
