Indications of shallow\r\ngas was observed as low gamma and high resistivity in a thin sand layer at 386\r\nm. No significant problems were encountered in the operations. The well was\r\ndrilled with spud mud down to 1542 m and with KCl/polymer mud from 1542 m to\r\nTD.\u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eThe prognosed Heimdal Formation was not\r\npresent in the well but a sandstone rich interval assigned to the Hermod\r\nFormation was encountered. In the Hermod Formation, a total of 31 m net\r\nreservoir sand was calculated between 2075.5 m and 2137.5 m. A Petroleum\r\nGeochemistry Study of the reservoir interval indicated significant amounts of\r\nmigrated hydrocarbons in the Hermod Formation. Traces of migrated hydrocarbons were\r\ndetected also in thinner sands in the Balder and Våle Formations. The reservoir\r\nproperties were excellent. An average porosity of approximately 30% has been\r\ncalculated based on petrophysical evaluation. Permeabilities greater than 3500\r\nmD are measured from core plugs. The hydrocarbon saturation is low and no\r\nevidence for moveable hydrocarbons was found in the log data. Fair to weak\r\nshows were recorded on cuttings from sandstones and limestone stringers from\r\nTop Balder Formation to TD, and good oil shows were recorded on sandston",
