North Sea Butch oil to head to Ula

Offshore staff

STAVANGER, NorwayCentrica Energy Norway and partners have decided to develop their Butch discovery in the southern Norwegian North Sea as a subsea tie-in to the BP-operated Ula field complex, 13 km (8 mi) to the west. 

The wellstream will be transported to the Ula platform for processing. Butch’s oil will be exported via the Ula oil export pipeline to the Ekofisk offshore complex and from there through the Norpipe trunkline to the Teeside terminal in northeast England.

Produced gas from Butch will be injected into the Ula field reservoir to improve oil recovery.

“The subsea tie-in is an innovative solution re-using the Oselvar infrastructure at the Ula platform,” said Henning Eide, Butch development manager at Centrica Energy Norway.

Centrica and partners Suncor Energy, Faroe Petroleum, and Tullow Oil evaluated several options for the development in license PL405, narrowed down to the subsea tieback and a standalone production jackup solution.

“The selected concept is an efficient solution that is seen as the best HSE concept, combined with robust economics. It also connects the field to a capable and experienced host operator,” Eide explained.    

The Butch field was discovered in 2011. Centrica estimates recoverable reserves in the range of 27-51 MMboe, of which 95% is oil. Production should start in 2019, building to a peak of 35,000 boe/d.

Centrica estimates total investments at NOK 6-7 billion ($732-854 million). The partners are due to take a final investment decision in late 2016.
