Well tests at the Pegasus West discovery have led to positive results, indicating a combined, sustained flow rate of more than 2.5 MMcm/d (90 MMcf/d) of gas, Centrica Energy said in a press release.

Centrica drilled the exploration well at Pegasus West using the Paragon 391 jackup rig as part of its strategy to build on its existing hubs. The Pegasus area is in the southern North Sea 150 km (93 miles) east of Teesside, England, close to the large Cygnus gas development where Centrica has a significant interest.

The Pegasus West well will now be suspended while the company assesses the data it has gathered and makes a decision on development.

Centrica Energy has a 55% operated interest in Pegasus, which includes the Pegasus North well drilled in 2011, along with partners Third Energy (35%) and Atlantic Petroleum (10%).
