Enhanced Oil Recovery
Full Form of EOR
What is EOR?
Enhanced Oil Recovery (EOR) refers to a set of advanced techniques used to extract additional crude oil from reservoirs after primary and secondary recovery methods have been exhausted. EOR involves injecting substances such as gases (e.g., carbon dioxide, nitrogen), chemicals (e.g., polymers, surfactants), or thermal energy (e.g., steam) into the reservoir to alter the oil's properties, improve mobility, and increase the overall recovery factor. In India, EOR is particularly significant for aging oil fields like those in the Gujarat and Assam basins, where state-owned Oil and Natural Gas Corporation (ONGC) and Oil India Limited (OIL) have implemented projects to boost domestic production and reduce import dependency. The technique is widely discussed in petroleum engineering curricula and is a topic in competitive exams like GATE and UPSC engineering services. EOR methods are chosen based on reservoir characteristics, cost, and environmental considerations, with carbon dioxide injection gaining attention for its dual benefit of enhanced recovery and carbon sequestration. Understanding EOR is crucial for professionals in the oil and gas sector, as it directly impacts national energy security and sustainable resource management.
