A review study: Development of microbial enhancing oil recovery technology

摘要

There are over 2 trillion barrels of conventional oil still remain reservoirs worldwide after conventional recovery methods have been exhausted. Based on these many techniques that involved in tertiary oil recovery were developed. However, most of these technologies restrict the further development of oilfields because of their economic limitations. Microbial enhanced oil recovery (MEOR) technique has been proposed for many years as a cheap and effective alternative to enhance oil recovery as its different processes generally do not depend on oil prices. MEOR pilot tests have been applied in many oilfields around the worlds. However, this method did not receive a great attention in the petroleum industry because of its technical bottlenecks. This paper is mainly focused on discussing the basic concept, mechanism, advantages, problems and further trends of MEOR.
