The higher costs were mainly due to\r\nkick off and orienting problems from the vertical well, lots of trips to change\r\nbits, milling cones lost in the 12 1/4" hole and problems cementing the\r\n7" liner. In general the drilling rate was lower than expected. Oil based\r\nmud (ANCO VERT) was used trough out the sidetrack. High mud weight (1.80 g/cm3)\r\nwas used in the beginning to prevent formation damage during drilling. This can\r\nhave caused lower ROP than expected. Prior to testing, a lot of leakage\r\nproblems occurred within the test string mainly due to bad quality of the\r\no-rings in the Halliburton test-valves. The string was pulled and reran 5 times\r\nbefore all the problems were sorted out. Total lost times in the test phase was\r\n893 hrs (squeeze cementing of 7" liner, leak in BHA of the test string,\r\nBOP problems, WOW, fishing of packer slips). \u003c/p\u003e\r\n\r\n\u003cp\u003eEleven cores were cut in the Tilje and\r\nÅre Formations. Two FMT samples were taken in the Garn Formation (4397.7 m TVD\r\nand 4402.7 m TVD, respectively) and one in the Tilje Formation (4806.8 m TVD).\r\nThe Garn samples contained water while the Tilje sample contained oil. The\r\n6506/12-10A well proved producible oil in the Garn, Ile, Tilje and upper parts\r\nof the Åre Formations in good sand intervals. After testing the well 6506/12-10\r\nA was permanently plugged and abandoned on 11 December 1995 as an oil and gas\r\nappraisal well. \u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eTesting \u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eThe test plan included short tests of the\r\nÅre and Tilje Formations followed by a long term production period.
