This season’s drilling programme follows a successful summer work programme which delivered over 30,000 tons of fuel, equipment and supplies in 120 barge runs from the Prudhoe Bay West Dock, some 60 miles west of the Point Thomson drilling site, the company said.

Dale Pittman, Alaska production manager of ExxonMobil, said: “We are making real progress at Point Thomson, and are on schedule to start production in 2014. The development plan we are pursuing will bring Point Thomson resources on production in a prudent, efficient and timely manner. ExxonMobil appreciates the hard work and accomplishments of Point Thomson contractors, as well as the diligence of the state and regional regulatory agencies, to move this important project forward. We are working to resolve the unit and lease dispute with the Department of Natural Resources to ensure Point Thomson’s development continues.”

The Point Thomson project will process 200 million cubic feet per day of natural gas in order to produce approximately 10,000 barrels per day of liquid condensate into the Trans Alaska Pipeline System, with capacity for up to 10,000 additional barrels of oil per day.

Point Thomson is a natural gas and condensate field located on Alaska’s North Slope. It holds an estimated 8 trillion cubic feet of gas – about 25% of the North Slope’s gas resource – and about 200 million barrels of condensate.
