Experimental study of effect of microbial enhanced oil recovery on rag Sefid reservoir
Author(s): Elyas Golabi
Abstract: In this work, we separate microorganisms from soil sample of Rag Sefid reservoir to produce bio-surfactant. This microorganism is belonging to Alcaligenes Sp family that the microorganism able to produce bio-surfactant. After produced bio-surfactant used for decrease interfacial tension between oil sample and water. Effect of four factors such as temperature, NacL concentration, pH and ratio of C/N on interfacial tension, were investigate. The experimental results shown the pH was not affected same as another factors. We were performed 16 experimental runs to reduce interfacial tension between oil and water and increase enhanced oil recovery in the core sample. Permeability of core was 54 m-Darcy. Minimum interfacial tension obtained was 20 mN/m. Results of core injection shown that maximum enhanced oil recovery was 11% and minimum enhanced oil recovery was 5%.
