Simulation Study on Reservoir Souring Induced by Injection of Reservoir Brine Containing Sulfate-Reducing Bacteria

Effects of nitrate injection on microbial enhanced oil recovery and oilfield reservoir souring.

Column experiments were utilized to investigate the effects of nitrate injection on sulfate-reducing bacteria (SRB) inhibition and microbial enhanced oil recovery (MEOR). An indigenous microbial consortium collected from the produced water of a Brazilian offshore field was used as inoculum. The presence of 150 mg/L volatile fatty acids (VFA´s) in the injection water contributed to a high biolog...

CRUDE GLYCEROL AS SUBSTRATE FOR SULFATE-REDUCING BACTERIA FROM A MATURE OIL FIELD AND ITS POTENTIAL IMPACT ON SOURING

Crude glycerol (CG) is an abundantly available and cheap by-product from biodiesel production. Value-added applications for CG are highly wanted by industry and several processes such as the use of CG for enhanced oil recovery have been proposed. The aim of this study was to evaluate the sulfide production of sulfate-reducing bacteria (SRB) indigenous to oil reservoirs using CG as substrate. Th...

Solving Reservoir Simulation Equations

Reservoir simulation is a necessary tool for making decisions. It is through numerical simulation that one can obtain knowledge pertaining to the processes occurring in the interior of an oil reservoir and hence, to enable an analysis of the various recovery strategies in order to guarantee optimal exploitation. History matching, optimization, and what-if scenarios require the simulation of lar...

Biocorrosion induced by Sulfate-Reducing Bacteria on Stainless Steel – A Preliminary Study

304 stainless steel was tested under the media without Sulfate-reducing bacteria (SRB) and with SRB. The corrosion behaviors of 304 stainless steel in SRB and without SRB medium were studied by measuring the open circuit potential, the polarization curves and electrochemical impedance Spectrum,weight loss measurements to get the changes of fore-and-aft corrosion fouling. The open circuit potent...
