Exploration well on the Halifax prospect, deviated WNW to test multiple fracture zones identified from seismic in Lewisian basement in inclined hole deep to dip-closure (3,412 ft TVDSS) and possible NE extension of the Lancaster oil field. Main hole junked with re-spud encountering oil and wet gas shows in Rona and Foula and in fractured basement from 2,765–6,057 ft TVDSS, over largely unfractured reservoir to TD. No flow from open-hole DST below closure and no valid pressures/samples from MDT.
