ConocoPhillips has received consent from the Petroleum Safety Authority (PSA) for production drilling on the Tor field (Tor II) offshore Norway using the West Linus mobile facility.

The Tor II oil and gas project encompasses the re-development of the Tor field, which is located in the Greater Ekofisk Area of the Norwegian North Sea.

Tor is jointly owned by Total E&P Norge (48.20%), ConocoPhillips Skandinavia (30.66%, operator), Var Energi (10.82%), Equinor Energy (6.64%) and Petoro (3.69%).

The approval covers the drilling and completion of eight production wells in connection with the new development of the Tor II field.

West Linus is a jack-up facility of the Gusto MSC CJ70-X150A type and is owned and operated by Seadrill.

PSA granted an acknowledgement of compliance (AoC) to the facility in 2014.

After remaining in operation for more than 37 years from 1978, the Tor field was shut down in 2015 following the expiry of the platform’s lifetime.

In July this year, ConocoPhillips submitted a plan for development and operation (PDO) for a redevelopment of the Tor field to Norwegian authorities.

The Norwegian Ministry of Petroleum and Energy approved the development plan for the field last month.

It is now redeveloped through a two-by-four slot Subsea Production System (SPS) with eight production wells and is planned to be connected to the Ekofisk Complex for processing and export.

ConocoPhillips and partners plan to re-start Tor II production next year.

In April, TechnipFMC secured an integrated engineering, procurement, construction and installation (iEPCI) contract for the Tor II development.
