STAVANGER, Norway – ConocoPhillips Skandinavia AS has submitted the plan for development and operation of the Tommeliten A field in the North Sea to the Norwegian Ministry of Petroleum and Energy and the UK’s Oil and Gas Authority.
Tommeliten A is a UK-Norway trans-boundary field as it extends from Norwegian block 1/9 into UK block 30/20.
The development concept is a two-by-six slot subsea production system with 10 production wells and an electrically heated flowline, tied into the Ekofisk complex, including installation of a new processing module. The field is about 25 km (16 mi) southwest of the Ekofisk complex.
Resource potential for the Tommeliten A field is estimated to be in the range of 80-180 MMboe, mainly comprising gas condensate.
The company estimates total capital investment to be about NOK 13 billion ($1.5 billion). First production is expected in 2024.
