Old Wells, New Tricks: EOR Market Set to Double

Global EOR market hits $61B in 2025 and is forecast to reach $118B by 2035, with US spending set to nearly double

14 May 2026

Ageing oilfields, tighter carbon rules and a new generation of digital tools are propelling the global market for enhanced oil recovery toward a near-doubling over the next decade, reshaping the economics of extracting crude from mature reservoirs.

Research published by SNS Insider on May 4 valued the worldwide EOR market at $61bn in 2025 and forecast it would reach nearly $118bn by 2035, implying a compound annual growth rate of 6.8 per cent. A separate assessment by Precedence Research placed US spending alone at $16.5bn in 2025, growing at 7.3 per cent annually. Those figures broadly align with the SNS estimates and point to the same underlying forces at work.

Most of that expansion is concentrated in the United States. American EOR spending stood at $15.5bn in 2025 and is projected to climb to $28.3bn by 2035, according to SNS Insider. North America commands roughly 38 per cent of the global market, a position underpinned by the Permian Basin's extensive carbon dioxide pipeline network, widespread use of thermal and steam injection techniques, and a large inventory of mature fields where conventional extraction methods have been exhausted.

Across the industry, operators are increasingly channelling capital toward extending the productive life of existing assets rather than committing to costly frontier developments. That shift has turned EOR, which encompasses techniques such as gas injection, chemical flooding and thermal recovery, from a secondary option into a core long-term investment.

Technology is compressing the cost base. Artificial intelligence-driven reservoir modelling, digital twin simulations and real-time sensors installed deep in wells are reducing the technical uncertainty that has historically slowed project approvals. Service companies including Halliburton and Schlumberger have integrated these tools into active operations, improving the predictability of recovery rates across complex geological formations.

Both research groups identify three converging pressures behind the spending trajectory: the need to redevelop mature fields, growing alignment between EOR and carbon capture objectives, and sustained investment in digital oilfield infrastructure.

How quickly the market reaches those forecasts will depend in part on oil price stability and the pace at which regulators formalise carbon storage credits. Both remain unresolved policy questions in Washington and Brussels alike.
