North Sea: Islay Development Approved

Paris, July 15, 2010 - Total announces that it has received approval from the United Kingdom Department of Energy and Climate Change (DECC) and the Norwegian Ministry of Petroleum & Energy (MPE) to develop its Islay gas field in the Northern North Sea, 440 kilometres north-east of Aberdeen.

The Islay field is located in Block 3/15 of the United Kingdom sector and partly across the median line in Blocks 29/6a and 29/6c of the Norwegian sector. Lying in a water depth of 120 metres, it has estimated reserves of near to 17 million barrels of oil equivalent and an estimated peak gas production rate of 2.5 million standard cubic metres per day plus associated condensates.

Total is the operator and sole owner of the Islay field as well as the Alwyn North, Dunbar, Grant, Ellon, Nuggets, Forvie North and Jura fields in the same region. Although a separate field, Islay is just 3 kilometres east of Jura and will be connected to Total’s Alwyn facility with first gas planned for the second half of 2011.

Yves-Louis Darricarrère, President of Total Exploration & Production, said: “We are delighted to have received the go-ahead to develop the Islay field. Along with our recently launched Laggan-Tormore, it forms the basis of an exciting portfolio of new production opportunities that is further strengthening Total’s presence in the North Sea and on the United Kingdom Continental Shelf.”
