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. 

ConocoPhillips Skandinavia AS is the operator of the Tommeliten A Unit with a 28.1385% ownership interest. PGNiG Upstream Norway AS (42.1978%), TotalEnergies EP Norge AS (20.1430%), Vår Energi AS (9.0907%), ConocoPhillips (U.K.) Holdings Ltd (0.2109%), TotalEnergies UK Ltd. (0.1510%), and ENI UK Ltd. (0.0681%) are unit partners. 

Discovered in 1977, Tommeliten A is a fractured chalk field containing gas condensate and volatile oil. The field consists of an Ekofisk Formation and a Tor Formation, similar to surrounding fields in the Greater Ekofisk Area.
