North America’s oil supply outlook is entering a new phase, according to Enverus’ latest long-term analysis. In this Insights episode of the Oil & Gas Journal ReEnterprised podcast, Mikaila Adams, content strategist and managing editor, speaks with Dane Gregoris, managing director at Enverus, and discusses the firm’s conclusion that US shale is “aging, not broken.”
While the United States is expected to remain the continent’s dominant producer, Enverus sees growth slowing markedly compared with the past two decades as operators work through increasingly mature inventories and confront geological constraints that are becoming harder to offset through efficiency gains alone.
The conversation examines the data behind that assessment, including declining productivity per lateral foot, changing inventory quality, and the methodology Enverus uses to estimate remaining drilling locations across North America’s major basins. Gregoris explains why the firm expects US production to remain relatively stable over the next decade rather than continue the rapid expansion that defined the shale revolution, and why rising marginal supply costs could become an increasingly important market signal.
A significant portion of the discussion focuses on the Permian basin, which Enverus still views as the cornerstone of North American oil supply well into the 2040s. At the same time, the report suggests that even the Permian is experiencing the effects of resource maturation. Gregoris discusses evidence that operators are moving down the quality curve and shares his perspective on emerging technologies, including ultra-long laterals, lightweight proppants, and advanced surfactants, that could improve recoveries and alter the industry’s long-term outlook.
The report’s second major theme is the growing strategic importance of Canada. As US shale growth moderates, Enverus sees Canada’s oil sands and liquids-rich plays as increasingly important sources of future supply. Gregoris explains why Canada’s resource base offers substantially longer inventory duration than most US plays and how pipeline development, condensate availability, natural gas infrastructure, and LNG export capacity will influence the pace at which that potential can be realized.
The discussion concludes with a look toward 2035 and the broader implications for energy security, capital allocation, and global oil markets. For readers interested in the intersection of geology, economics, infrastructure, and policy, the episode provides a detailed examination of how Enverus believes the North American energy map could evolve as the industry’s most productive shale resources mature.
