Premier Oil UK Ltd. and partners will assess commercial prospects of their Bagpuss prospect offshore Scotland after their 13/25-1 well cut 41 ft of hydrocarbon-bearing sands in a 68-ft hydrocarbon column (OGJ Online, Aug. 16, 2013).
The sands have 25-33% porosity, and the oil is heavy, as expected.
The well, on Block 13/24c on the western margin of the Halibut horst in the Outer Moray Firth, reached 1,532 ft TD in granite basement. It has been plugged.
The well “has proven a significant volume of oil in place,” said Robin Allan, Premier director of exploration and North Sea.
An Amoco well drilled about 2 km away in 1981 encountered hydrocarbons on the same structure.
Premier operates the block with a 40.1% working interest. Other working interests are Maersk Oil UK, 25%; North Sea Energy (UK NO2) Ltd., 15%; EnCounter Oil, 13.27%; and Groliffe, 6.63%.
