Abstract:
Abstract The need to maximize oil production from petroleum reservoirs has prompted the evaluation of several recovery techniques in the oil and gas industry. The primary energy of a reservoir can only account for about 20 – 40% of the initial oil in place, leaving quite a significant volume still residual in the reservoir. Microbial enhanced oil recovery is a tertiary recovery technique utilizing the potential of certain microbes to significantly influence oil production from the reservoir with different mechanisms of recovery. This study focuses on investigating oil recovery by increasing its mobility due to viscosity reduction as a result of dissolved biogenic gases produced during microbe-oil reaction. Results showed that viscosity of a crude sample initially at 27cp reduced to about 0.002cp as a result of the soluble biogenic gases produced by the microbe. A significant increase in the oil permeability and cumulative oil production due to a reduced viscosity was also recorded. Keywords: MEOR, Microbes, Solubility, Viscosity
