A 36" hole was drilled from\r\n103 - 178 m. The 30" casing was set at 176.5 m. A 9 7/8" pilot hole\r\nwas drilled to 1160 m. No shallow gas was observed. The hole was opened up to\r\n17 1/2" down to 1160 m and the 13 3/8" casing was set at 1153 m. The\r\nwell was drilled with seawater down to 176.5 m and with Ancotec oil based mud\r\nfrom 1176.5 m to TD.\u003c/p\u003e\r\n\r\n\u003cp\u003eThe well encountered the Skagerrak\r\nFormation sands at 2564 m. A total of 140.5 m of these sands were drilled\r\nbefore the well was terminated at 2725 m. Of this, petrophysical evaluation\r\ngave 134.4 m net sand with 20.3 % average porosity. The entire reservoir was\r\nwater bearing. No shows were reported from any section of the well.\u003c/p\u003e\r\n\r\n\u003cp\u003eTwo cores were cut from 2562 to 2626 m in\r\nthe Skagerrak Formation.
