Oil and gas was encountered in the Early to Middle Jurassic Båt and Fangst Groups. The well was drilled with seawater and hi-vis pills down to 802 m, Gyp/PAC mud from 802 m to 2242 m, Anco 2000 with glycols (Anco 208) from 2242 to 4378 m, and with Ancotherm mud from 4378 to TD. A total of 13 cores were cut in this well. Two were cut in the Paleocene Tang formation but these only 0,35m was recoverd(1%)The other 11 cores were cut in the interval 4415 m to 4846.9 m in the Båt and Fangst Groups. Recoveries for these were from 65 to 100%. Three FMT samples were taken in the Tilje Formation.\r\nThe well was abandoned as an oil and gas appraisal on 11 September 1993.\r\n\u003c/p\u003e\r\n\u003cb\u003e\r\nTesting\r\n\u003c/b\u003e\r\n\u003cp\u003e \r\nFive production tests were performed in the Jurassic sandstone section.\r\nDrill stem test no 1 in the Åre formation in the interval 4846.0 to 4876 m produced a near-critical gas condensate. The well production was 444 000 Sm3/day of gas and 840 Sm3/day of condensate through a 44/64\" (17,46 mm) choke size. Density of the gas was 0.832 (air = 1) and condensate density was 0.814 g/cm3.\r\nDrill stem test no 2 tested the Tilje formation in the interval 4805.0 to 4834 m, and it produced a light oil. The well production was 249 000 Sm3/day of gas and 900 Sm3/day of oil through a 56/64\" (22,23 mm) choke size. Density of the gas was 0.832 (air = 1) and condensate density was 0.855 g/cm3.\r\nDrill stem test no 3 tested the Tilje formation in the interval 4742.0 to 4751.0 m, and it produced a light oil. The well production was 138 000 Sm3/day of gas and 567 Sm3/day of oil through a 44/64\" (17.46 mm) choke size. De",
