Enhanced oil recovery refers to methods used to extract additional oil from reservoirs after primary and secondary recovery techniques have been exhausted.
Instead of relying on natural reservoir pressure alone, EOR introduces external energy or agents, such as gas injection, chemicals, or heat, to mobilize remaining oil. The result is increased recovery factors, extended field life, and improved capital efficiency.
CO₂ injection is one of the most commonly used EOR techniques in the industry today. Injected carbon dioxide reduces oil viscosity and increases reservoir pressure, allowing previously trapped hydrocarbons to flow more freely. Throughout enhanced oil recovery projects, accurate placement, pressure monitoring, and equipment integrity are essential to maintaining well performance and avoiding unintended consequences.
