This was a new geological\r\nprovince and hence the well was a true wildcat. The well was drilled up-dip of\r\na rotated fault block at Late to Middle Jurassic level. The primary purpose of\r\nthe well 7219/8-1 S was to test the Middle Jurassic Stø Formation. A secondary\r\nobjective was to test possible sandstone in Late Jurassic Hekkingen Formation,\r\nand finally, to test possible sandstone in a defined stratigraphic trap in the\r\nEarly Cretaceous sequences.\u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eOperations and results\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eWell 7219/8-1 S was spudded with the semi\r\nsubmersible installation Ross Rig on 5 October 1992 and drilled to TD at 4611.5\r\nm, 91 m into the Early - Middle Jurassic Stø Formation. The well was drilled\r\ndeviated towards northwest with a direction of approximately 294 degrees with\r\napproximately 22 degrees inclination. Kick off point was at 1396 m. No shallow\r\ngas was identified. The well was drilled with spud mud down to 1018 m and with\r\nKCl / polymer / Anco 208 (glycol additive) mud from 1018 m to TD. It was one of\r\nthe first to be drilled with a glycol mud system to inhibit reactve shales. \u003c/p\u003e\r\n\r\n\u003cp\u003eDown to the Base Cretaceous at 3471.5 m\r\n(3343 m TVD RKB), the well penetrated mainly claystones. The shallowest\r\nprospect, the Cretaceous sequence, was penetrated in a distal position, and\r\nhence was most likely shaled out. The Jurassic comprised the Late Jurassic\r\nHekkingen and Fuglen Formations and the Early to Middle Jurassic Stø Formation.\r\nThe secondary Hekkingen prospect was penetrated about 720 m deeper than\r\nprognosed and was only 9 m thick. Pressure test indicated a tight formation.\r\nThe large difference between the prognosed and actual depth was mainly due to a\r\nmuch thicker Early Cretaceous sequence than prognosed. The main prospect, the\r\nStø Formation, was penetrated 450 m deeper than prognosed. The Sandstone with\r\nporosity in order of 5-8%, was water bearing. The relatively tight sandsto",
