Enhanced Oil Recovery

Enhanced Oil Recovery (EOR) is a strategic and advanced technique employed in the oil and gas industry to maximize the extraction of hydrocarbons from reservoirs that have already undergone primary and secondary recovery methods. The primary goal of EOR is to increase the overall recovery factor of oil and gas fields, ensuring the efficient utilization of these valuable resources. Commonly employed EOR methods include thermal, chemical, and gas injection techniques, each tailored to the specific characteristics of the reservoir. Thermal EOR methods involve the injection of heat into the reservoir to reduce the viscosity of the oil, making it easier to flow and increasing the overall recovery efficiency. Steam injection and in-situ combustion are prominent examples of thermal EOR techniques. Chemical EOR methods, on the other hand, utilize the injection of polymers, surfactants, and other chemicals to alter the properties of the reservoir fluids and enhance oil mobility. Gas injection techniques, such as carbon dioxide (CO2) injection, displace oil by increasing reservoir pressure and reducing the oil's viscosity. The success of EOR projects relies heavily on the understanding of reservoir characteristics, fluid behaviour, and the careful selection of suitable EOR methods. Advanced reservoir simulation tools play a crucial role in predicting the outcomes of EOR projects and optimizing operational parameters.
