Total has announced the launch of the Laggan and Tormore gas fields development in the offshore frontier region of the West of Shetland, subject to the UK Government’s Department of Energy and Climate Change approval.
The company also announced the acquisition of the 10% interest in Laggan and Tormore previously held by Chevron North Sea Ltd and the 20% interest previously held by ENI UK Ltd. This brings Total’s interest in this project to 80% alongside partner DONG E&P (UK) Ltd.
This groundbreaking subsea project and its associated infrastructure is key to unlocking further opportunities in the Greater West Shetland region, prompting an increase in exploration and development activity in the area.
Laggan and Tormore development
The Laggan and Tormore gas fields, which lie approximately 140 km West of Shetland by 600 m of water depth in Blocks 206/1a, 205/4b and 205/5a, have global estimated reserves of approximately 230 million bbls of oil equivalent. At peak, gas production rate of 500 million ft3/d is expected from the two fields, plus associated condensates (for a total production of 93 000 bpd of oil equivalent).
Construction work on the offshore gas infrastructure, and on a new gas processing plant at Sullom Voe on Shetland, will start almost immediately, with first gas production planned for 2014.
After processing at the new Sullom Voe plant, Laggan and Tormore gas will transit through a new 230 km export pipeline from Shetland into the existing Frigg UK line and onward to the Total operated Saint Fergus gas terminal, located north of Aberdeen.
