Few technical problems occurred during\r\nthe drilling period. The well was drilled with spud mud down to 820 m, with\r\ngypsum/polymer mud from 820 m to 3115 m, and with gel/lignosulphonate mud from\r\n3115 m to TD.\u003c/p\u003e\r\n\r\n\u003cp\u003eTop Cretaceous was encountered at 2132 m.\r\nGrey brownish sediments of the Early Cretaceous were found unconformable on reddish\r\nLate Triassic sediments at 3066 m. Early Cretaceous sand and silt layers had indications\r\nof hydrocarbons at a depth of 2195 m. Similar indications were seen in a silt at\r\n2580 m to 2595 m, some thin sandstones at 2856 to 2904, and a possibly\r\nCenomanian to Turonian age sand at 2987 m. Fluorescence and cut was observed on\r\nthin sandstones in the core at 3009 m. Further spots of weak shows were\r\nobserved on several cuttings and SWC sandstone samples from the Triassic\r\nbetween 3154 m and 3496 m. Logs displayed that all observed shows were residual\r\nhydrocarbons. \u003c/p\u003e\r\n\r\n\u003cp\u003eOne core was cut from 3009 m to 3020 m.
