Point Thomson is the remote gas field Alaska's pipeline dream depends on

You know Prudhoe Bay. You probably don't know Point Thomson — the remote, pricey field Alaska's whole pipeline dream quietly leans on. And it's stirring.

Most Alaskans have heard of Prudhoe Bay. Far fewer know Point Thomson — and that's strange, because the future of Alaska's gas line may hinge on it.

Point Thomson is a gas and condensate field out on the Arctic coastal plain, east of Prudhoe Bay, in one of the hardest places on the continent to build anything. ExxonMobil owns about 60% of it; Hilcorp Alaska owns the rest. As Hilcorp senior vice president Luke Saugier has put it, the field is "exceptionally remote, which makes it very, very expensive to develop."

So why does it matter? Because it holds a major share of the North Slope's natural gas — the same gas the proposed 800-mile Alaska LNG pipeline is built to carry to market. The plan even includes a separate 62.5-mile line to move Point Thomson's gas over to Prudhoe Bay and into the larger system, up to 865 million cubic feet a day. Without that gas in the mix, the economics of the whole project get harder.

Which is what makes a dry-sounding state filing worth a second look. On June 21, the Department of Natural Resources posted an application to expand the Point Thomson unit — the kind of administrative step that can come before bigger moves on a field. The state will take public comment before deciding whether to approve it.

For a project Alaska has chased for decades, the small steps at Point Thomson are worth watching. The application and comment details are posted on the Alaska Online Public Notices portal.
