Abstract
Microbial EOR (MEOR) methods rely on microorganisms and their metabolic products to mobilize residual oil in several different ways. MEOR mechanisms include interfacial tension reduction, selective plugging, gas production, biodegradation, and wettability alteration. A discussion on MEOR covers its mechanisms; background information on enhanced oil production; comparison of MEOR with traditional EOR methods; bacteria that produce biosurfactants which reduce oil-water interfacial tension; selective plugging; test injected bacteria solution; viscosity reduction; wettability alteration; bacteria delivery; bacteria flooding; and feeding existing bacteria.
