Exploration well, deviated north from the Forties Alpha platform to the Les Arcs prospect, an Upper Jurassic embayment into the Forties-Montrose High with a Fulmar Sandstone at 9,850 ft to objective at 11,800 ft. Prospect required a lateral seal to the south against Rattray Volcanics. Main hole was junked in the Sele after suffering total losses. The sidetrack proved a 303 ft TVT Fulmar section at 14,888 ft (11,087 ft TVDSS), with 197 ft TVT net sand and an average porosity of 29%. Sands were water-wet with an Sw of 88%. No significant reservoir was seen in the Pentland.
