ABERDEEN, UK – Centrica Norge has submitted a development plan for the Oda (ex-Butch) field in North Sea license PL405 to the Norwegian Ministry of Petroleum and Energy.

Oda, in the northern Norwegian North Sea, was discovered in 2011 in shallow water, 13 km (8.1 mi) east of the BP-operated Ula complex.

The proposed development calls for a four-slot seabed template with two production wells and one water injection well, tied back to the Ula platform, now operated by Aker BP.

Produced oil will head through the Norpipe system to the Teesside Terminal in northeast England; the gas will be sold at the platform to Ula for re-injection into the Ula reservoir to improve recovery.

According to Faroe, a partner in both Oda and Ula, the tie-in is an innovative solution that involves reusing the existing Oselvar infrastructure (Faroe 55% and operator) from the Ula platform.

Production from Oselvar will cease in order to allow Oda production to flow and the Oselvar owners will be compensated accordingly.

Faroe adds that over the past two years the Oda partnership, which also includes Suncor Energy and Aker BP, has managed to reduce investment costs by more than 40% to around NOK5.4 billion ($635 million).

Production is scheduled to begin in 2019 and build to around 35,000 boe/d. Oda contains estimated 2P reserves of 42 MMboe.
