LONDON -- Serica Energy may drill two more prospects next year in its Slyne basin acreage off western Ireland.
The company operates license FEL 01/06, comprising blocks 27/4, 27/5 (west), and 27/9. They cover an area of 611 sq km (234 sq mi), and are around 40 km (24.8 mi) south of Shell’s offshore Corrib gas field development.

Last year Serica discovered sub-commercial oil with the Bandon exploration well 27/4-1. The company has since identified other potentially commercial oil prospects, and has acquired well-site survey data in preparation for wells in 2011 on one or both of the Boyne and Liffey prospects.

In Ireland’s offshore Rockall basin, Serica has a 100% interest in license FEL 1/09, comprising six blocks in the northeastern part of basin, and covering a total area of 993 sq km (383 sq mi).

Three exploratory wells have been drilled to date throughout the Rockall basin, which extends over 100,000 sq km (38,610 sq mi). Of these, Enterprise’s 12/2-1 Dooish gas-condensate discovery, 9 km (5.6 mi) south of Serica’s license, encountered a 214-m (702-ft) hydrocarbon column.

Recently Serica shot several new 2D long-offset seismic lines across Muckish, a large structure it had identified from existing 3D seismic, which covers 30 sq km (11.6 sq mi) in a water depth of 1,450 m (4,757 ft).
