  • 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.

  • Deposit monitor
    Patent number: 10295489
    Abstract: Fluid flow systems can include one or more resistance temperature detectors (RTDs) in contact with the fluid flowing through the system. One or more RTDs can be operated in a heating mode and a measurement mode. Thermal behavior of the one or more RTDs can be analyzed to characterize a level of deposit formed on the RTD(s) from the fluid flowing through the system. Characterizations of deposition on RTDs operated at different temperatures can be used to establish a temperature-dependent deposition profile. The deposition profile can be used to determine if depositions are likely to form at certain locations in the fluid flow system, such as at a use device. Detected deposit conditions can initiate one or more corrective actions that can be taken to prevent or minimize deposit formation before deposits negatively impact operation of the fluid flow system.
