Microbial Enhanced Oil Recovery (MEOR) represents one of the promising methods to extract the remaining immovable hydrocarbons from different reservoirs. Selection of bacteria is the important criteria for recovering the immovable residual hydrocarbons. The investigation on Clostridium tyrobutyricum 90F and DSMZ 663 strain in North Sea – been studied in laboratory for different salinity, pressure and temperature conditions in carbonate formation based on different physical and chemical conditions of the reservoir. The fundamental understanding of structure and function of Clostridium tyrobutyricum and its linkage to biogeochemistry in reservoirs and understanding of mechanisms in MEOR environmental, microbial and physiological process is a prerequisite to developing microbial methods to enhance the quantity and quality of the hydrocarbon (HC) recovery. The average porosity increase value was about 0.04 representing an increase of about 11% per sample. Also density of the sample is increased due to the bulk volume of the samples that generally reduced due the dissolution of the rocks after microbial treatment.
