Oil major ConocoPhillips unit ConocoPhillips Scandinavia and its partners in the Tor Unit have started production from Tor II field located in the Norwegian part of the North Sea.

The Tor II oil and gas project is a redevelopment of Tor field previously on production from 1978 until 2015.

It is located in 80m-deep waters in the Greater Ekofisk Area in the Norwegian North Sea.

According to ConocoPhillips, Tor II redevelopment is the first redevelopment of a shut-in field on the Norwegian Continental Shelf (NCS).

Tor unit 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%).

In July, ConocoPhillips and partners submitted a plan for development and operation (PDO) for the Tor II development.

ConocoPhillips Europe, Middle East and North Africa president Steinar Vaage said: “Having produced the Tor field for 37 years, we are proud to continue to extend development enabling an expected production lifetime beyond 60 years.

“Tor II is utilising available Greater Ekofisk Area capacity for processing and transportation.”

ConocoPhillips noted that the total capital investments are now estimated at around Nkr6.4bn (approximately $725m).

The project plan comprises two new subsea templates with eight production wells, planned to be connected to the Ekofisk Complex.

The Tor II development has a Brent cost of supply below $30 per barrel.

In October, ConocoPhillips secured consent from the Norwegian Petroleum Directorate (NPD) to start up the Tor II field facilities.
