Well 34/8-3 found oil and gas in\r\nthe Brent Group without encountering the OWC. Well 34/8-3 A was sidetracked\r\ndown flanks on the structure to establish the OWC and to test if the A-North\r\ncould be in communication with the 34/8-1 A-South Discovery.\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 34/8-3 A was kicked off at\r\n944 m in the primary well on 14 November 1988. It was drilled with the\r\nsemi-submersible installation Polar Pioneer to TD at 3230 m (3091 m TVD) in the\r\nEarly Jurassic Cook Formation. During logging before setting of 9 5/8",\r\nthe tool got stuck at 1284 m. The string was cut, and the instrument was fished.\r\nThe well was drilled with KCl/polymer mud from kick-off to TD.\u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eSpotted hydrocarbon shows were described\r\non cuttings in the interval 2550 to 2660 m in the Kyrre Formation. Top Draupne\r\nFormation was encountered at 3003 m. Under Draupne, the sidetrack penetrated a\r\n19 m thick Heather Formation sequence that was not present in the primary well\r\nbore. The Brent Group, Tarbert Formation was encountered at 3031 m (2900 m TVD),\r\ndeeper than prognosed due to the unexpected Heather. The Brent Formation\r\ncontained gas down to a gas/oil contact at 3059 m (2927 m TVD and oil down to a\r\nclear oil/water contact at 3099.5 m (2966 m TVD). Oil shows continued down to\r\n3162 m. The Cook Formation was found water bearing. The RFT pressures in both the\r\nprimary well and the sidetrack proved higher pressure in the hydrocarbon zone\r\nthan on the A-South compartment, but with pressure communication in the water\r\nzone.\u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eFive cores were cut in the interval 3034\r\nto 3148.5 m.
