Effects of nutrient injection on the Xinjiang oil field microbial community studied in a long core flooding simulation device

Frontiers in Microbiology, 2023
Microbial Enhanced Oil Recovery (MEOR) is an option for recovering oil from depleted reservoirs. Numerous field trials of MEOR have confirmed distinct microbial community structure in diverse production wells within the same block.

Possible Use of Biosurfactant Produced by Microbial Consortium from Contaminated Soil for Microbially Enhanced Oil Recovery

Chemical Engineering Transactions, 2017
Despite recent efforts to introduce renewable energy sources to the market, the world still relies heavily on crude oil and petroleum-based products. It is estimated that over two-thirds of the crude in an oil reservoir remains untouched.
