The primary objective was the basal Late Jurassic sand. This sand\r\nwas estimated to have an approximate gross thickness of 71 metres.\u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eOperations and results\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eWildcat well 16/8-1 was spudded with the\r\nsemi-submersible installation Nordskald on 25 September 1976 and drilled to TD\r\nat 2301 m in the Triassic Smith Bank Formation. The well was drilled with\r\nseawater and gel down to 172 m and with Drispac and seawater from 172 m to TD. \u003c/p\u003e\r\n\r\n\u003cp\u003eNo reservoir sands were encountered in\r\neither the Paleocene or the Triassic. From 1769 m to 1820 m in the Late\r\nCretaceous Tor and Hod Formations chalks with calculated porosities from 17% to\r\n34% were encountered. At 2073 the well penetrated a gross thickness of 43 m of\r\nLate Jurassic Intra Draupne sand. This sand was of high porosity but water\r\nbearing. No evidence of hydrocarbons was encountered while drilling, and log\r\nanalysis confirmed all intervals with significant porosity to be water bearing.\r\nCanned samples for source rock/maturity analysis by Robertson Research were\r\ncollected every 100 m from 1000 m and every 30 m from 2000 m to TD. This study\r\nshows that the penetrated sections are immature. Samples from the Draupne\r\nFormation show good source characteristics with TOC from 3% to 7% and one\r\nextract from this section contained minor amounts of probably locally generated\r\nhydrocarbons. No conventional cores were cut and no fluid samples taken. The\r\nwell was plugged and abandoned as a dry hole on 29 October 1976. \u003c/p\u003e\r\n\r\n\u003cp\u003e\u003cb\u003eTesting\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp\u003eNo drill stem test was performed\u003c/p\u003e\r\n\r\n\r\n",
