The structure is salt induced and consists of a northern, western,\r\neastern and a southern compartment. Oil is proven in the northern compartment\r\nby the 7/11-5 well in the Late Jurassic Ula formation sandstone. The reservoir\r\nsandstone was deposited in a shallow marine environment mainly by storm\r\nepisodes into an approximately 100 km long and 20 km wide "fairway".\r\nShales of the Late Jurassic Farsund- and Mandal formations make up the\r\ncap-rock. The well was to be vertical down to 2002 m MSL and then kicked off\r\ntowards the target with an angle of 33.28 degrees. The primary objective was a\r\nlong term test production from the oil-bearing Ula formation of Area 1 in the\r\nnorthern compartment. Secondary objective was to improve the geological\r\ncontrol, and coring was supposed to give good information about the silica\r\ncementation above and below the OWC. Shallow gas was indicated in the interval\r\nfrom 318 m - to 425 m MSL.\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 7/11-10 S was spudded with\r\nthe semi-submersible installation Transocean 8 on 5 July 1990 and drilled to TD\r\nat 4566 m in the Triassic Smith Bank Formation. No shallow gas of importance,\r\nonly background gas, was encountered while drilling. Gumbo problems were\r\nencountered in the upper part of the 17 1/2" hole, but hole conditions\r\nimproved after increasing the mud weight. The well was kicked off at 2010 m in\r\n40° direction, and the angle built to 35° at 2610 m. While pulling out, the bit\r\ncame out with three cones lost. The string got stuck at 3740 m. Fishing\r\noperation was unsuccessful, and a cement plug was set above the fish. The hole\r\nwas kicked off from the cement plug at 3550 m and sidetracked. No severe\r\nproblems were experienced in the last part of the hole except from low\r\npenetration rate at times and some tight spots on the bit trips. The top hole\r\nwas dr",
