Statoil has decided to cancel the Stena Carron rig contract after two dry wells on pre-salt targets in Kwanza Basin blocks 38 and 39. “Statoil’s first well results from the area have been disappointing and, although the company still sees remaining prospectivity in the basin and on the Statoil acreage, more time is needed to evaluate the well results and mature new prospects before deciding on future activities,” the company said.So far this year, Statoil has suspended Diamond Offshore’s Ocean Vanguard rig, Saipem’s Scarabeo 5, China Oilfield Services Limited’s COSL Pioneer, Transocean’s Spitsbergen, and Songa Offshore’s Songa Trym.
