Microbial enhanced oil recovery

Microbial-enhanced oil recovery involves injection of carefully chosen microbes. Subsequent injection of a nutrient is sometimes employed to promote bacterial growth. Molasses is the nutrient of choice owing to its low (ca 100/t) cost. The main nutrient source for the microbes is often the cmde oil in the reservoir. A rapidly growing microbe population can reduce the permeabiHty of thief zones improving volumetric sweep efficiency. Microbes, particularly species of Clostridium and Bacillus, have also been used to produce surfactants, alcohols, solvents, and gases in situ (270). These chemicals improve waterflood oil displacement efficiency (see also Bioremediation (Supplement)).

In Chapter 1, Microbial Enhanced Oil Recovery (MEOR) was defined as the use of microbes in the oil wells, in situ to enhance production of oil and prolong their active life cycle. Most conventional oil recovery processes are able to retrieve only, approximately 50% of the oil at the well. Theoretically, microbes are supposed to act by either ...

Microbial enhanced oil recovery (MEOR) typically involves the use of bacterial cells for in situ production of chemicals in an oil well. The method has been found to be appropriate in recovering more oil from stripper wells (producing less than 10 barrels per day) thus, economic constraints result in restricted operating procedures. The organisms, nutrients, such as molasses, and air (for aerobic operation), are fed into the wellbore. Then, the well is closed for up to a few weeks to allow the cells to multiply and produce EOR chemicals, which can include gases, solvents, acids, biomass, and natural polymers.
