This exploration well was drilled from the Forties Alpha Platform and deviated approximately three miles to the north-east to test the Upper Jurassic Les Arcs prospect in block 22/6e. Les Arcs is a Fulmar stratigraphic pinch-out, with closure mapped at approximately 9,850–11,800 ft within an embayment into the northern flank of the Forties-Montrose High. The 21/10-F4 main hole was abandoned tight and the 21/10-F4Z sidetrack was abandoned dry, with good quality but water-wet Fulmar reservoir.
