The last part in a two-part series which describes 10 field cases involving 221 producing wells in Malaysia, the US, Argentina, and China is presented. Microbial enhanced oil recovery (MEOR) projects carried out during the last 10 years provide a basis for characterizing the types of reservoirs suitable for MEOR applications. Offshore Malaysia, Bokor field received MEOR treatments. The producing reservoir in the field has good 50-4,000 md permeability and produces viscous oil. Operators in the US have reported very few MEOR field cases in the past 10 years, possibly because they have been reluctant to reveal their production data. Argentina MEOR operations include huff-and-puff projects in Piedras Coloradas field. Receiving the bacteria treatments were two wells in Barrancas formation and four wells in Blanco formation. Several Chinese oil companies also have implemented MEOR projects. The Maling block in Changqing oil field was one of the fields with MEOR field tests.
