The primary objective was to test the potential\r\nfor hydrocarbon production from Danian and Late Cretaceous Limestones on a low\r\nrelief structural closure. Secondary objective was a possible stratigraphic\r\ntrap potential in Early Cretaceous sandstones.\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 2/7-16 was spudded with the\r\nsemi-submersible installation Nortrym on 20 March 1980 and drilled to TD at\r\n4818 m in the Early Cretaceous Ågard Formation. The well was drilled with\r\nSeawater/Native Solids mud down to the 13 3/8" casing point at 1523 m,\r\nwith Seawater/Lignosulphonate from 1523 m to the 9 5/8" casing point at\r\n3794 m, and with Calcium chloride/Sodium chloride XC polymer mud from 3794 m to\r\nTD.\u003c/p\u003e\r\n\r\n\u003cp\u003eHydrocarbon shows were encountered in the\r\nDanian and Upper Cretaceous limestone. The porosity was poorly developed and\r\ntesting verified the zones to be non-productive. Early Cretaceous had shows in\r\nlimestones, claystones, shales, and marls, but no sandstones were found.\u003c/p\u003e\r\n\r\n\u003cp\u003eThirteen conventional cores were cut\r\ncontinuously from 3182 m to 3402 m in the Ekofisk and Tor Formations\r\nFormations. Twenty-five RFT measurements were attempted in the gross interval\r\n3823.8 - 4783.6 m. A fluid sample was obtained at 4587.9 m. It contained 50 ml\r\nformation water and 39 cubic feet (1.1 Sm3) gas.\u003c/p\u003e\r\n\r\n\u003cp\u003eThe well was permanently abandoned on 12\r\nJuly 1980 as a dry well with shows.\u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eTesting\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eTwo drill stem tests were conducted. DST\r\n1 at 3279.7 to 3288.8 m in the Tor Formation produced 660 barrels (105 m3) of\r\nwater /day, with traces of oil and gas. DST 2 from the intervals 3193.1 -\r\n3199.8 and 3201.4 - 3215.4 m in the Ekofisk Formation produced 28.8 barrels\r\n(4.6 m3) water /day with no oil or gas before acid treatment. Well died\r\ncompletely after acid, with only a very weak flow of acid gas.",
