The objective of the well was to\r\ntest an interpreted Late Jurassic submarine fan prospect within the Viking\r\nGroup. If successful, the well would prove a new play fairway on the Halten\r\nTerrace.

A 9 7/8" pilot hole\r\nwas drilled to 1100 m in the event of shallow gas. No gas was encountered. The\r\nwell was opened up and drilled with seawater and hi-vis pills down to 1106 m\r\nand with gyp/polymer mud from 1106 m to TD.\u003c/p\u003e\r\n\r\n\u003cp\u003eTop Viking Group was encountered at 4094\r\nm, 30m shallower than prognosis. No major sandstone was penetrated at prospect\r\nlevel or within the Viking Group.\u00A0 Minor sandstone and limestone horizons were\r\npenetrated within the Upper Cretaceous (Lange Formation,\r\nEarly Turonian). These horizons were hydrocarbon bearing, recorded on logs as\r\nwell as in the form of oil shows. Due to bad hole conditions no wire line logs\r\nwere run below 3491 m. MWD GR and resistivity logs were however run below this\r\ndepth. No cores were cut and no fluid samples were taken. The well was\r\npermanently abandoned on 7 June 1992 as a dry well with shows\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",
