Drilling has got under way on the Rowallan exploration well in the central North Sea, project partners said today.

The Ensco 121 jack-up rig is drilling the high pressure, high temperature gas condensate prospect, according to Serica Energy, which has a 15% stake in the well.

Italian firm Eni is the operator and JX Nippon and Mitsui are the remaining partners.

London-listed Serica is fully carried for the exploration well, which is expected to take around 140 days to drill. 

A competent person’s report estimated that the prospect could yield 20-60 million barrels of oil equivalent net to Serica.

If the well goes to plan, the nearby Dundonald and Sundrum prospects could be included in a wider development project. 

Such a campaign could also extend to Serica’s recently awarded 30th Round blocks directly to the south.

Rowallan is located in the vicinity of Total’s Culzean field and Shell’s Shearwater platform.
