The main objective of the well was to prove presence of sandstone and\r\nhydrocarbons in the Draupne Formation. The wells earlier drilled in the H-Area,\r\n34/7-21, -21 A in H-Sentral and -23 S and -23A in H-Vest, proved oil bearing Late\r\nJurassic Intra Draupne Formation sand. The discoveries in H-Sentral and H-Vest\r\nwere however not in direct pressure communication. Well 34/7-24 S was drilled\r\nin a structural low compared to the other wells in the area and was mainly\r\ndesigned to test the continuity of the discovery made in H-Vest 34/7-23\r\nS&A. The 34/7-24 S well was prognosed to penetrate top reservoir 63 m below\r\nthe deepest penetrated ODT in the area. No OWC had been proved in the H-Area\r\nand the 34/7-24 S well was placed structurally relatively deep in order to\r\npossible reach an OWC in case of a sand bearing top Draupne interval. \u003c/p\u003e\r\n\r\n\u003cp\u003eSecondary objectives of the well were\r\npossible gravity deposited sandstones within the Middle and Lower Draupne\r\nSequences\u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eOperations and results\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eWell 34/7-24 S was spudded with the semi-submersible\r\ninstallation Vildkat Explorer on 25 February 1995 and drilled to TD at 3145 m (2938 m TVD) 54 m TVD into Late Jurassic sediments of the Heather Formation.\r\nDue to the nearness to the Snorre-Statfjord pipeline at the target position the\r\nwell had to be drilled deviated. The distance between the spud and the target\r\nposition at Base Cretaceous level was approximately 900 m. The inclination was\r\nbuilt from vertical to 28 deg through the 12 1/4" section from 335 m to\r\n1296 m. Operations went without significant problems. The well was drilled with\r\nspud mud down to 1296 m, and with a pseudo-oil based mud system (NOVAMUL) from\r\n1296 m to TD. There was interpreted possible shallow gas from the MWD logs\r\nbetween 361 to 365 m. The zone did not show anything on the ROV or at the flow\r\ncheck.",
