Application of thermotolerant petroleum microbes at reservoir conditions for enhanced oil recovery

Petroleum, 2023
Primary oil recovery is the first stage of hydrocarbon production in which a reservoir uses its natural energy to force hydrocarbon to its wellbore. Secondary oil recovery comes to play when hydrocarbons can no longer be further produced by natural means.

Microbial Enhanced Oil Recovery

, 2016
The ever-rising global demand for energy and the issue of large volumes of unrecovered oil after primary and secondary oil production operations are driving the development and/or advancement of enhanced oil recovery (EOR) techniques. Conventional EOR processes include thermal, immiscible and miscible gas injection, chemical, and microbial enhanced oil

Comparison of microbial community structures between oil and water phases in a low-permeability reservoir after water flooding

Energy Reports, 2023
The application of Microbial Enhanced Oil Recovery relies heavily on the microorganisms in oil wells. However, due to the difficulties in separating bacteria from oil samples, studies on bacterial communities in oil samples are limited.
