BP Exploration Operating Co. has encountered gas-condensate in reservoirs of varying quality at the North Uist exploratory prospect on the Atlantic margin west of the Shetland Islands.
BP spudded the 213/25c-1V well on Mar. 25, 2012, and went to 4,700 m true vertical depth. It encountered several reservoir objectives, the most significant of which was the North Uist prospect, said Faroe Petroleum PLC, Aberdeen, which has a 6.25% carried interest. Commercial potential is yet to be evaluated.
BP collected extensive data including wireline logs, pressure data, and sidewall cores. A full formation and volume evaluation is under way. The shallower Cardhu prospect encountered traces of hydrocarbons.
The North Uist deepwater frontier exploratory well, which was plagued with drilling difficulties, is 110 km northwest of Sullom Voe on Blocks 213/20b, 214/16b, and 213/25c. The wellsite is near Chevron's Rosebank oil discovery, also on the Corona ridge. The Stena Carron drillship will plug the well as planned.
Faroe Petroleum noted that the well proves another working hydrocarbon system in the frontier west of the Shetlands. The partnership will analyze the considerable collected data before proceeding.
