Due to\r\nhigh gas readings and subsequent problems with increased mud weight and lost\r\ncirculation up to 14% oil was added to the mud at 3799 m. This mud was\r\nsubsequently circulated out and displaced with new mud, but a level of 1% to 8%\r\noil was recorded in the mud from 3799 m to TD. Due to high formation pressure\r\nand safety problems, drilling was terminated in Late Jurassic shales before\r\nhaving reached the target Middle Jurassic sand.\u003c/p\u003e\r\n\r\n\u003cp\u003eShows were reported from lowermost Chalk\r\nGroup, limestones of the Cromer Knoll Group, and from Upper Jurassic Dolomite\r\nand sandstone stringers.
