UK-based Centrica is reportedly examining four potential development options for its Butch Main discovery in offshore Norway despite drilling dry at the site earlier this year.

The company is considering investment plans between $600 million and $1.2 billion to bring Butch Main online in either 2018 or 2019, Offshore.no said.

Centrica is looking into numerous options that include subsea tiebacks to the Talisman operated Gyda platform or the BP operated Ula platform, installing a wellhead platform that can be linked to Gyda or Ula or using a standalone mobile offshore drilling and production unit.

Centrica’s Butch South West exploration well 8/10-6S and wildcat well 8/10-6 S drilled dry in July.

Butch Main was discovered in late 2011 in the Centrica operated production license 405.

The prospect contains light crude in the Upper Jurassic reservoir of the Ula formation.

Current reserves are estimated at between 27 million and 51 million barrels of oil equivalent.

A company spokesman said Centrica plans to move forward with development although he did not say if more exploration wells will be drilled.

Centrica operates PL 405 with a 40 percent interest. Calgary-based Suncor holds a 30 percent stake. UK-based Faroe Petroleum and UK-based Tullow Oil each hold 15 percent stakes.
