  • Use of sulfonium salts as corrosion inhibitors
    Patent number: 10900128
    Abstract: The present invention generally relates to the use of aryl sulfonium salts as a corrosion inhibitor in a water injection system, a hydrocarbon extraction system, or a hydrocarbon production system. Treating oilfield injection and produced fluids with aryl sulfonium salts can significantly decrease microbially induced corrosion. Thus, these aryl sulfonium salts can be effectively used as corrosion inhibitors in oilfield fluids.
    Type: Grant

  • Use of sulfonium salts as hydrogen sulfide inhibitors
    Patent number: 10301553
    Abstract: Uses of aryl sulfonium salts for lowering sulfide concentrations and for preventing growth of microbes in a water injection system, a hydrocarbon extraction system, or a hydrocarbon production system are disclosed. Treating oilfield injection and produced fluids containing high levels of microbes with aryl sulfonium salts can significantly decrease the amount of hydrogen sulfide produced, which can be used to measure sulfidogenesis. The treatment can also decrease the number of active microbes in the injection and produced fluids. Thus, these aryl sulfonium salts can be effectively used as inhibitors of hydrogen sulfide generation and as biocides in oilfield fluids.

  • Diphenyliodonium salts as sulfidogenesis inhibitors and antimicrobials
    Patent number: 10098346
    Abstract: The present invention generally relates to the use of diphenyliodonium salts for lowering sulfide concentrations and for preventing growth of microbes in a water injection system, a hydrocarbon extraction system, or a hydrocarbon production system. Treating oilfield injection and produced fluids containing high levels of microbes with diphenyliodonium salts can significantly decrease the amount of hydrogen sulfide produced, which can be used to measure sulfidogenesis. The treatment can also decrease the number of microbes in the injection and produced fluids. Thus, these diphenyliodonium salts can be effectively used as inhibitors of hydrogen sulfide generation and as biocides in oilfield fluids.
