ConocoPhillips Skandinavia AS and partners submitted a plan for development and operation of Tommeliten A field in the North Sea to the Norwegian Ministry of Petroleum and Energy and the UK Oil and Gas Authority. First production is expected in 2024.
Tommeliten A is a UK-Norway trans-boundary field extending from Norwegian Block 1/9 into UK Block 30/20. New greenfield facilities are about 25 km southwest of the Ekofisk complex in 75 m of water. It is being developed in accordance with the UK and Norwegian authorities’ guidelines for development of trans-boundary oil and gas fields.
The reservoir, at a depth of 3,000 m, contains gas and condensate in chalk in the Paleocene Ekofisk formation and Upper Cretaceous Tor formation (OGJ Online, Oct. 1, 2020). The development concept is a two-by-six slot subsea production system (SPS) with ten production wells and an electrically heated flowline, tied into Ekofisk, including installation of a new processing module. Resource potential for the field is estimated to be 80-180 MMboe, mainly comprising gas condensate.
Estimated total capital investment associated with the project is $1.5 billion.
ConocoPhillips Skandinavia AS is operator of Tommeliten A Unit (28.1385%) with partners PGNiG Upstream Norway AS (42.1978 %), TotalEnergies EP Norge AS (20.1430 %), Vår Energi AS (9.0907 %), ConocoPhillips (UK) Holdings Ltd. (0.2109%), TotalEnergies UK Ltd. (0.1510%), and ENI UK Ltd. (0.0681%).
