Northern Alaska

Description

The North Slope of Alaska is a foreland basin formed in the Mesozoic and Cenozoic in response to crustal loading by the Brooks Range, an orogenic belt produced by collision of the continental Arctic Alaska plate with an island arc. The foreland basin developed on an older passive margin sequence composed of Mississippian to Cretaceous clastic and carbonate rocks. Cross sections have demonstrated the characteristic structural and stratigraphical relations. The paleogeography during formation of the passive margin consisted of a land mass to the north and the open ocean to the south in present-day coordinates. Land and sea relations were reversed during foreland basin development with the orogenic ancestral Brooks Range highlands in the south and the marine basin to the north.

Summary

The North Slope is undergoing a renaissance. Santos' Pikka field achieved first oil in May 2026 and is ramping up to 80,000 b/d, ConocoPhillips' Willow (peak c. 180,000 b/d) is under construction, and the March 2026 NPR-A lease sale was the first since 2019. State forecasts see Alaskan output rising by about a third over the next decade.
