ABERDEEN, UK -- Total and partner DONG have sanctioned development of the Laggan and Tormore gas/condensate fields 140 km (87 mi) west of the Shetlands. Total also has increased its interests in the two field to 80%, after agreeing to buy the equity previously held by Chevron and ENI.
Laggan and Tormore are in UK blocks 206/1a, 205/4b, and 205/5a in 600 m (1,968 ft) water depth, with combined reserves estimated at 230 MMboe. At peak, Total foresees a gas production rate of 500 MMcf/d from the two fields, plus associated condensates, bringing a total production of 93,000 boe/d.
Production will be exported subsea to a new processing plant at Sullom Voe, Shetland, and will then head through a new 230-km (143-mi) export pipeline from Shetland into the existing Frigg UK line and onward to the Total-operated gas terminal at St Fergus, north of Aberdeen.
Construction of the offshore and onshore infrastructure will start soon, pending approval from the UK’s Department of Energy and Climate Change, with first gas slated for 2014.
Yves-Louis Darricarrère, president Exploration & Production said the project is in one of the most complex environments on the UK continental shelf, and would require investment nearing $3.83 billion.
The company added in its statement that this project and its associated infrastructure is key to unlocking further opportunities in the Greater West Shetland region, and should trigger increased exploration and development activity in the area by Total and other operators.
