The main objectives of the well were to establish\r\nthe Ti1je gas/oil contact, to define Tilje and Åre oil properties, and to\r\ninvestigate the Åre oil/water contact. In addition, the well was expected to\r\nprove Fangst erosion and established lateral continuity of Tilje reservoir\r\nproperties.\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 6507/7 6 was spudded with\r\nthe semi-submersible installation Nortrym on 23 July 1986 and drilled to TD at 2525 m in Early Jurassic sediments of the Åre Formation. At 419 m the drill\r\nstring torqued up and spun out five joints below the kelly, dropping the string\r\nto the seabed. The well was re-spudded after being moved approximately 8 m, and\r\nthis time drilling proceeded without significant problems. The well was drilled\r\nwith seawater and pre-hydrated gel sweeps down to 1030 m and with KCl/polymer\r\nmud from 1030 m to TD.\u003c/p\u003e\r\n\r\n\u003cp\u003eOil shows were recorded in 3 m thick\r\nsandstone at 2096 m in the Cretaceous. A marked unconformity separates the\r\nMiddle Jurassic from the overlying Late Cretaceous sequence. The total hiatus\r\nwas from Aalenian-Bajocian to Campanian-Santonian. Top Middle Jurassic Fangst\r\nGroup, Ile Formation was encountered at 2144.5 m and was gas bearing. From good\r\nquality RFT pressure data, cores, and electric logs a gas/oil contact was established\r\nat 2339 m in the Tilje Formation and the oil/water contact at 2440 m in the Åre\r\nFormation. Shows continued down to 2445. Below this depth no shows were\r\nreported.\u003c/p\u003e\r\n\r\n\u003cp\u003eA total of 191 m core was recovered from\r\nthe well. Two cores were cut from the Early Cretaceous through the Fangst Group\r\nand into the top Båt Group (2129 - 2185 m), and eight cores were cut from the\r\ngas zone in the lower part of the Tilje Formation, through the OWC and into the\r\nÅre Formation (2305 - 2462 m). One RFT run was made in the 12 1/4" hole. A\r\nwater sample was at",
