On 2 December permission was granted to continue\r\noperations and drilling continued to 2610 m. On 26 December the well was again\r\nsuspended at the request of the Norwegian Petroleum Directorate because of\r\nsafety considerations in adverse weather conditions. The well was re-entered on\r\n13 March 1986 and drilled to a TD of 4003 m in basement rocks. The well was\r\ndrilled with seawater and bentonite hi-vis pills down to 485 m.
