Serica Energy plc has announced that exploration well 22/19c-7, drilled to explore the Rowallan prospect in the central North Sea, has reached a total depth of 4641 m and will be plugged and abandoned.

The well, operated by ENI UK Ltd., encountered a 182 m section of sandstone and shale, but was not found to be hydrocarbon bearing. The well was high pressure and high temperature and drilled using managed pressure drilling and continuous circulating technology. The well was drilled on time and on budget. Serica was fully carried and did not pay any of the costs of the well.

Serica’s partners in the well were ENI UK Ltd. 32% (operator), JX Nippon 25%, Mitsui 20% and Equinor 8%.

Mitch Flegg, Chief Executive of Serica Energy, commented: “We are naturally disappointed that the well has not encountered hydrocarbons. We will now assess the valuable data acquired before deciding the forward plan for the remaining prospects on block 22/19c and adjacent blocks. This result justifies our policy of reducing financial exposure to exploration risk by means of farm-out. In this case we were fully carried and did not pay anything towards the cost of the well. We remain fully committed to building on our balanced exploration, development and production portfolio.”
