ConocoPhillips has made a discovery at its Cassin prospect, but details remain scarce.

Earlier this year, ConocoPhillips drilled the Cassin No. 1 exploration well to meet work commitments of its Bear Tooth unit in the National Petroleum Reserve-Alaska.

The “wildcat” well made a discovery, ConocoPhillips EVP of Exploration & Production Matt Fox said during a quarterly earnings call with investors this morning. But while Fox announced the discovery, he offered no details about its size or about future plans.

ConocoPhillips has made discoveries in the NPR-A through its previous exploration work, but development has been constrained by permitting and infrastructure. The company is currently working on its first NPR-A development project with the Alpine West/CD-5 satellite, a project that would pave the way for future westward expansion.
