Kappa is an elongated down faulted block bounded by north south\r\ntrending major faults to the east and the west. The structure is an easterly\r\ntilted fault block where the Base Cretaceous truncates both the Brent Group and\r\nthe Statfjord Formation. The main objective of the well was to prove\r\nhydrocarbons in the Statfjord Formation by drilling on a location that leaves a\r\nminimum of possible reserves up dip of the well. Secondary objectives were to\r\nimprove stratigraphical and structural knowledge of the area and to acquire\r\ninput data for further exploration activity in blocks 30/6 and 30/9.\u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eOperations and results\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eWildcat well 30/6-18\r\nwas spudded with the semi-submersible installation Byford Dolphin 1 August 1985\r\nand drilled to TD at 3690 m in Late Triassic rocks. Drilling proceeded without\r\nany significant problems. The well was drilled with spud mud down to 658 m and\r\nwith a KCl polymer mud from 658 m to TD. The Statfjord Formation came in 120 m\r\nhigher than prognosed. The logs show that the Statfjord Formation contains 16 m\r\nof gas and 44 m of oil. Oi1/water contact was defined at 3181 m. The reservoir\r\nquality seems to be good. There is a separate column of 19 m oil further down\r\nin the Statfjord Formation. A thick shale sequence from 3287 to 3305 m\r\nseparates the upper reservoir unit from the lower. The lower oil column is\r\nprobably restricted to only one layer of sand with a gas cap on top. Eight cores\r\nwere cut in the Statfjord Formation in the interval 3126 - 3215 m. Three sets\r\nof segregated RFT samples were retrieved from 3165 m, 3125.5 m, and 3312.8 m in\r\nthe Statfjord Formation. The well was plugged and abandoned on 23 November 1985\r\nas an oil and gas discovery.\u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eTesting \u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eThree drill stem\r\ntests were performed in this well. The intervals were 3306 m - 3323 m, 3198 m -\r\n3210 m and 3164 m & 3173.2 m.\u003c/p\u003e\r\n\r\n",
