Laboratory simulation of microbial enhanced oil recovery using Geobacillus toebii R-32639 isolated from the handil reservoir

Microbial enhanced oil recovery (MEOR) is a biological based technology to enhance crude oil (CO) recovery at old oil wells by manipulating function or structure or both of the microbial environments existing in oil reservoirs. Even if many biosurfactant-producing microbes can be found in different...
