ConocoPhillips has let contracts to Aker Solutions for modifications on the Ekofisk installations to integrate the Tommeliten Alpha discovery, offshore Norway.
The front-end engineering and design (FEED) contract starts immediately and is expected to be completed in second-quarter 2021. The service company values the contract at 130 million kroner. The contract includes an option for the engineering, procurement, construction, and installation (EPCI) work following the completion of the FEED, subject to Norwegian authorities' approval of the plan for development and operation and a new award decision by the Tommeliten Alpha partnership.
The FEED work will be led by Aker Solutions’ office in Stavanger, Norway.
A contract to deliver the subsea production system for the development also was awarded to Aker Solutions. The estimated contract value is 1.2 billion kroner. The scope of work covers a complete subsea production system including 10 vertical subsea trees, two manifolds, wellheads, satellite structures, control systems, and tie-in equipment.
Tommeliten Alpha, in the southern part of the Norwegian sector in the North Sea some 25 km southwest of Ekofisk field, was proven in 1977. Water depth at the site is 75 m. 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. Four wells were drilled on the discovery, the last one in 2003, according to the Norwegian Petroleum Directorate web site. Development of Tommeliten Alpha has been stopped two times at the concept selection stage. Different alternatives for a development of the discovery are being studied, all based on a tie-back to Ekofisk.
ConocoPhillips Skandinavia AS is operator for the Greater Ekofisk Area (35.11 %). Other license owners are Total E&P Norge AS (39.90 %), Vår Energi AS (12.39%), Equinor Energy AS (7.60 %), and Petoro AS (5.00 %).
