Which production phase injects steam,natural gas,or CO₂ into the well to extract more oil?

Question

Quizplus · Accepted Answer

Injecting steam, natural gas, or chemicals like COS into the well to extract more oil is known as tertiary production or enhanced oil recovery (EOR). This method is used after primary and secondary production phases have been completed, and it aims to recover more oil from the reservoir by changing the physical properties of the oil or the reservoir rock. Pumpjacks are used in the primary and secondary production phases to mechanically lift the oil to the surface, while fracking is a method used to extract oil and gas from unconventional reservoirs like shale formations.
