We have identified a class of inhibitory molecules that abrogate sulfidogenesis in oilfield produced fluids. Bottle tests and laboratory-scale bioreactors to mimic field conditions, found that very low doses of two versions of this class of compounds were found to effectively prevent H2S generation.

Reservoir souring remains a challenging problem for the oil & gas industry, especially in aging assets where H2S and microorganisms from the reservoir can pose a serious risk to the integrity of producing wells and equipment. Nitrate treatment is commonly used to control SRB activity in the reservoir, but it is not always effective due to poor subsurface definition and increasing volumes required over time. In this study, we evaluated the use of a biocide to replace nitrate injection in reservoir conditions when nitrate is no longer effective to control SRB activity. We used sour, sand-packed reactors to evaluate a biocide formulation applied prior to and after nitrate cessation. Measurements of VFAs, nitrate, sulfide and genomic analysis were used to assess souring and changes in the microbial population. The results indicated that biocide was successful to remediate souring when applied before AND after the nitrate treatments. However, the cumulative amount of generated sulfide was higher when the biocide was applied after nitrate cessation, indicating the need of temporary co-injection of nitrate and biocide to prevent a H2S wave period. Genomic analysis indicated that this formulation specifically targeted the SRB rather than broadly killing the microbial population. Taken together, this study highlights a new strategy to control reservoir souring and potential corrosion issues in producing wells.

Validation of a New Thin-Film Culture Device for Detecting Sulfate-Reducing Microbial Species

Product Number: MECC23-19975-SG

Sulfate-reducing bacteria (SRB) constitute a specialized group of phylogenetically diverse anaerobes that are responsible for the dissimilatory reduction of sulfate to sulfide. They are present in a variety of environments, including oil- and gas-bearing formations, soils, and domestic, industrial, and mining wastewaters (1,2). SRB are a major concern in the oil and gas industry with significant economic and safety implication.
