The well was drilled with Bentonite\r\n/ CMC EHV down to 917 m, with "ANCO 2000" mud from 917 m to 2316 m,\r\nand with oil based "ANCOVERT" from 2316 m to TD.\u003c/p\u003e\r\n\r\n\u003cp\u003eDrilling performance\r\nwas good down to 3731 m but very low penetration rate was experienced below\r\nthis level to TD due to very hard formation.\u003c/p\u003e\r\n\r\n\u003cp\u003eThree cores were\r\ncut, one in Spekk Formation (shale), one in Rogn Formation II and one in Melke\r\nFormation. One FMT run was performed in the Rogn and Melke sandstone sections.\r\nThe FMT log was run with sample chambers to collect a sample of the formation\r\nfluid if possible. All the pressure points showed tight formation. The well was\r\npermanently abandoned on 17 October 1995 as a dry well.\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\r\nwas performed.\u003c/p\u003e\r\n\r\n\r\n",
