It was planned to be drilled in two phases and the primary\r\nobjective was to test sandstones of the Brent Group. Secondary objectives were\r\nsandstones in the Paleocene and in the Lower Jurassic, Cook and Statfjord\r\nformations.\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 30/3-1, Phase I was spudded with the\r\nsemi-submersible installation Nordskald and drilled to 3718 m in claystone and\r\nmarls of the Early Cretaceous Cromer Knoll Group. Phase I was drilled without\r\nserious problems but the 12 1/4" hole section had to be cut shorter than\r\noriginally planned due to lost circulation and possibly higher pore pressures\r\nthan prognosed. The mud gas readings were relatively high through the 17 1/2"\r\nsection causing long periods of circulation. The well was drilled with seawater\r\nand hi-vis pills down to 212 m, with a gel mud from 212 m to 985 m, and with a\r\nSpersene XP 20/Magcogel/nut plug mud from 985 m to TD. \u003c/p\u003e\r\n\r\n\u003cp\u003eThe Paleocene did not contain good\r\nreservoirs. Shows and live oil in the mud were however recorded in predominant\r\nclaystone lithology from 1910 m to 2470 m. No conventional cores were cut and\r\nno fluid samples taken. \u003c/p\u003e\r\n\r\n\u003cp\u003eThe well was suspended on 7 September as\r\na dry hole after the 9 5/8" casing was run. The plan was to re-enter the\r\nwell later, using a rig equipped with a 15000 psi BOP stack and drill through\r\nthe Jurassic sandstones.\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\r\n",
