E.ON E&P has said that the size of the Tolmount gas discovery in the UK North Sea could be larger than was originally estimated around two years ago, making it one of the largest discoveries made in this part of the North Sea for several years.

The company completed the appraisal well and reached its targets within time and budget on 6 July 2013, while a 855m side-track was completed on 30 July.

E.ON board of management member, Jørgen Kildahl, said: "This successful discovery in [the] UK is an important step for our growing upstream business. Tolmount will significantly contribute to the implementation of our business strategy."

"Tolmount could be one of the largest discoveries made in the southern North Sea in the last decade," E.ON E&P CEO Frank Sivertsen added.

"In October 2011, E.ON first announced it had encountered gas on the UK Tolmount prospect, located in Block 42/28d."

The well targeted the Permian Leman Sandstone Formation and encountered a gas column in excess of 200ft. The well test flowed at a maximum stable rate of 50 million standard cubic feet of gas per day.

The Tolmount discovery is located 50km off the UK coast, to the north-east of Dimlington, East Riding of Yorkshire.

Sivertsen said: "The well results will now be incorporated into development studies, with the aim of an optimised development in a short timeframe."

The well is operated by E.ON E&P with a 50% stake and the remaining 50% is owned by Dana Petroleum.
