The well was drilled with seawater and high viscosity pills down to\r\n622 m, Anco 2000 with glycol from 622 to 2140 m, and with oil based Anco vert\r\nfrom 2140 m to TD. Unexpected high formation pressure was encountered at TD and\r\nthe mud weight was raised according to this. The Tilje reservoir zone and Åre 2\r\nFormation proved to be hydrocarbon bearing as expected. Three cores (179 meter\r\ncored and recovered) were cut from the Tilje and Åre Formations. Two MDT fluid\r\nsamples were taken at 4674 m in the Tilje Formation. The well was suspended on\r\n10 November 1996 as an observation well for an extended test to be carried out\r\nin well 6506/12-11 S R. The well was then re-classified from oil and gas\r\nappraisal well to development well 6506/11-G-1 H. \u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eTesting \u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eThe well was perforated in the Tilje 1.1\r\nReservoir Zone (4671 - 4685 m) and permanent pressure gauges were installed.\r\nOnly a short clean up flow was carried out before the pressure gauges were\r\ninstalled so no flow rates were recorded. Due to technical problems with the\r\npressure test string the test was abandoned and no pressure data to confirm\r\ncommunication with well 6506/12-11 S R was obtained.\u003c/p\u003e\r\n",
