The well was drilled with seawater gel,\r\nadding lignite from 2150 m.\u003c/p\u003e\r\n\r\n\u003cp\u003eThe Cretaceous sequence consisted of the\r\nLate Cretaceous Tor and Hod chalk formations resting unconformably on a very\r\nthin Late Jurassic Draupne shale. Thirty-seven net m of good quality sand was\r\nencountered in the Jurassic Hugin Formation. The Triassic consisted of red beds\r\nwith no major sand development. The Zechstein contained tight anhydritic\r\ndolomite, some vuggy dolomite, and shales, while the Rotliegendes Group had poor\r\nreservoir quality dolomite cemented sandstones, siltstones and shales. A shows\r\non a core was recorded in the interval 2345 m to 2350.7 m in the upper part of\r\nthe Jurassic Hugin Formation. Otherwise no hydrocarbons were encountered in the\r\nwell. Two cores were taken in the 8 1/2" section, in the interval 2342 m\r\nto 2365.5 m in the Jurassic Hugin Formation. Forty sidewall cores were taken in\r\nthe interval 2296 m to 3130 m. No fluid samples were taken. The well was\r\npermanently abandoned as dry on 28 August 1982.\u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eTesting\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eNo drill stem test was performed\u003c/p\u003e\r\n\r\n\r\n",
