The main problem in operations\r\nwas the discovery of a washout in the well head 18 3/4" ax seal area after\r\nsetting 9 5/8" casing. This was repaired so that drilling could proceed,\r\nbut it was decided not to do the planned DST due to possible leak. Otherwise,\r\noperations proceeded without significant problem. The well was drilled with seawater\r\nand gel down to 644 m and with gel and lignosulphonate from 644 m to TD.\u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eThe Vestland Group, Hugin Formation was\r\nencountered at 3483 m.
