A 12\r\n1/4” pilot hole was drilled from 250 m to 950 m to check for shallow gas. The\r\nwell was situated ca 90 m south of the location for the well 34/10-10, which\r\nwas abandoned due to gas flow from a gas filled sand at 428 m. The same\r\nsandlense was penetrated in the well 34/10-15 from 444-447 m. The well was\r\ndrilled with spud mud down to 250 m and with gel/seawater/lignosulphonate mud\r\nfrom 250 m to TD.\u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eWeak shows on cuttings, mostly on\r\nlimestone, were recorded intermittently from 1220 m in the Hordaland Group to\r\n1630 m in the Lista Formation.
