Kinetic investigation of microbial souring in porous media using microbial consortia from oil reservoirs

Microbial souring (H[sub 2]S production) in porous media was investigated in an anaerobic upflow porous media reactor at 60 C using microbial consortia obtained from oil reservoirs. Multiple carbon sources (formate, acetate, propionate, iso and n-butyrates) found in reservoir waters as well as sulfate as the electron acceptor were used. Kinetics and rates of souring in the reactor system were analyzed. Higher volumetric substrate consumption rates (organic acids and sulfate) and a higher volumetric H[sub 2]S production rate were found at the front part of the reactor column after H[sub 2]S production had stabilized. Concentration gradients for the substrates (organic acids and sulfate) and H[sub 2]S were generated along the column. Biomass accumulation throughout the entire column was observed. The average specific sulfate reduction rate (H[sub 2]S production rate) in the present reactor after H[sub 2]S production had stabilized was calculated to be 11.62 [+-] 2.22 mg sulfate-S/day g biomass.
