The primary objective was to\r\ntest the reservoir and hydrocarbon potential in the Ula Formation. In the event\r\nof a discovery the plan was to complete the well as a producer.\u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cb\u003e\u003cspan lang=EN-GB\u003eOperations and results\u003c/span\u003e\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eOperations on wildcat well 7/12-12 S\r\nstarted on 9 October 1995. The well was drilled from the Ula Platform and was kicked\r\noff at 547 m in existing development well 7/12-A-10 the 14th of November 1995. After drilling to 16"\r\nhole section TD at 2498 m the hole packed off and the string got stuck. Several\r\nattempts were made to retrieve the fish, but failed. A balanced kick-off plug\r\nwas set and the well was sidetracked (7/12-12 S T2) from 958 m and drilled to\r\nfinal TD at 6079 m (4067 m TVD) in interbedded sands, silts and shales of\r\npossible pre-rift age. The well was drilled with Enviromul oil based mud from\r\nkick-off to TD. Considerable hole problems occurred during drilling. There is a\r\ndiscrepancy of up to 7 m between drilled and logged depth below 5482 m. Depths\r\ngiven here are drilled depths.\u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eTop Reservoir (Ula Fm) was penetrated at\r\n6018 m MD (4020 m TVD), 118 m TVD deeper than predicted.
