The Enhanced Oil Recovery market is defined by three primary technology categories: thermal, chemical, and gas injection. According to Market Research Future, the Enhanced Oil Recovery Market is projected to reach USD 76.20 billion by 2035. The Enhanced Oil Recovery Market types thermal chemical gas represent the main approaches to unlocking trapped hydrocarbons, each suited to specific reservoir conditions.

Thermal Injection: The Dominant Technology

Thermal injection is the largest segment, accounting for 47.5% of the market share in 2025. This technique involves injecting heat into the reservoir to reduce the viscosity of heavy oil, making it easier to flow. The most common methods are steam injection (cyclic steam stimulation and steam-assisted gravity drainage) and in-situ combustion. These methods are particularly effective for heavy oil and bitumen reservoirs. Canada, Venezuela, and China are the primary markets for thermal EOR. The thermal injection segment is sustained by heavy-oil steam-flood operations across these regions.

Gas Injection: The Fastest-Growing Segment

Gas injection is the fastest-growing technology, with a projected CAGR of 6.9% through 2035. This technique involves injecting gases like CO₂, natural gas, or nitrogen into the reservoir to maintain pressure, reduce oil viscosity, and improve sweep efficiency. Miscible CO₂ injection is particularly effective, as the CO₂ mixes with the oil, making it less viscous and easier to produce. The growth of this segment is fueled by the increasing availability of anthropogenic CO₂ from industrial capture facilities and supportive policies like the U.S. Section 45Q tax credit.

Chemical Injection

Chemical injection involves injecting polymers, surfactants, and alkalis into the reservoir to improve oil recovery. Polymer flooding increases the viscosity of the injected water, improving its sweep efficiency. Surfactant and alkaline flooding reduces the interfacial tension between the oil and water, mobilizing the trapped oil. This technique is widely used in China's Daqing and Shengli fields. The Enhanced Oil Recovery Market is characterized by this diverse portfolio of technologies.
