Premier Oil abandons North Sea well

In 2012, Premier drilled five exploration wells targeting tertiary sands in the UK Central North Sea.

This resulted in the success at Carnaby, within the greater Catcher Area, and the company said its tertiary prospect drilling in the UK would now concentrate on this area.

It plans to spud the Bonneville well in March 2013, while a higher impact exploration programme in the North Sea focusing on deeper Mesozoic plays will see drilling begin at its Luno II and Lacewing prospects in the first quarter of 2013.
