ConocoPhillips proposes natural gas pipeline from Alaska to lower 48 states and Canada

HOUSTON — ConocoPhillips said Friday it plans to develop a multibillion-dollar pipeline that would transport natural gas from Alaska to the lower 48 states and Canada.

The oil exploration and production company said it's "prepared to make significant investments, without state matching funds, to advance this project."

ConocoPhillips spokesman Charlie Rowton said the company's best estimate for the entire project, including the pipeline from Alaska's North Slope to Chicago, is between $25 billion and $42 billion.

The pipeline would provide an important avenue for bringing Alaska's massive stores of natural gas to U.S. markets that rely on it for heating homes and other uses. It would move about 4 billion cubic feet of natural gas per day.

The U.S. consumed about 21.7 trillion cubic feet of natural gas in 2006, according to the Energy Department.

In a statement, ConocoPhillips Chairman and Chief Executive Jim Mulva said the company hopes to work directly with the state to advance the project as quickly as possible.

"We also expect to approach other parties to explore ways through which their participation could add value to this effort," Mulva said.

Specifically, Rowton said Exxon Mobil Corp. and BP PLC would be logical participants as the project moves forward. Partnering with a pipeline company also is a possibility.

"We think it makes sense for there to be other owners," he said.

BP spokesman Steve Rinehart in Alaska said he couldn't speculate on whether the company would be interested in partnering with ConocoPhillips, but it had no intention of submitting its own bid. Rinehart added, however, "we think a successful gas project is very important."

Exxon Mobil said it had no comment.

ConocoPhillips said it is already gathering data to support the pipeline permit application.

During the initial phase of the project, Bechtel Oil, Gas and Chemicals Inc. will provide construction and design support, the company said.

Shares of ConocoPhillips rose 1 cent to $78.83 in early afternoon trading Friday. The shares have traded in a range of $61.59 to $90.84 in the past year.

Friday was the deadline for applications from companies interested in building the pipeline.
