Alaska LNG can overcome challenges, ExxonMobil executives say

November 21, 2013

Steve Butt, an ExxonMobil executive leading the Alaska LNG team, said his group is working to reduce uncertainties in the project and whittle the cost estimate to the lower end.

"Our role is to get to $45 billion, we don't like $65 billion," he said, adding that natural gas is simply a commodity and that price is key to buyers.

Butt noted that the team he leads represents the first time that all three major North Slope producers — ExxonMobil, ConocoPhillips and BP — have worked together with an experienced northern pipeline operator, TransCanada, on a project to move North Slope gas to market in the four decades since the Prudhoe Bay oil and gas discovery.

Butt described for the audience of several hundred people — mostly Alaskan business people and policy makers — the details of the LNG project as defined in its early stages:
• Produce about 3.5 billion cubic feet of gas a day from the Prudhoe Bay and Point Thomson fields.
• A massive gas treatment plant to cleanse the gas of about 400 million to 500 million cubic feet a day of carbon dioxide. The treatment towers will be 120-feet tall and 28-feet wide, with 1-foot-thick steel walls to contain the high pressures of treatment. About 12 percent of Prudhoe's gas is CO2.
• An 800-mile, 42-inch diameter buried pipeline, with eight compressor stations to move the gas and keep it chilled. Among the challenges will be operating a buried chilled-gas pipeline without disturbing discontinuous permafrost where the soils are alternately frozen and unfrozen, traversing the narrow and steep Atigun Pass in the Brooks Range, and spanning the Yukon River. Crossing the Susitna River and crossing Cook Inlet in Southcentral Alaska to reach the LNG plant on the Kenai Peninsula will be easier tasks, Butt said.
• The plant at Nikiski, featuring three liquefaction trains — or manufacturing lines — LNG storage tanks and two tanker berths on Cook Inlet than could accommodate a ship every two days on average. The team continues to study the ice and strong tides on Cook Inlet and "we have a lot of confidence we can make this work," Butt said.
