What does EOR stand for?

• A. Extended Oil Recovery
• B. Enhanced Oil Recovery
• C. Environmental Oil Recovery
• D. Efficient Oil Recovery

Answer: (B)

EOR stands for Enhanced Oil Recovery. This term is used for methods that improve the amount of oil that can be extracted from a reservoir beyond what natural flow or basic water flooding would achieve. The word “Enhanced” signals that these techniques are designed to boost recovery, not just extract oil as it comes. “Oil” identifies the resource, and “Recovery” refers to bringing that oil to the surface. This distinguishes EOR from primary recovery (the reservoir’s natural drive) and secondary recovery (like water flooding). The other options don’t match standard industry terminology—“Extended” isn’t the established term, “Environmental” shifts focus away from recovery, and “Efficient” is too generic to denote a specific class of recovery methods.
