  • Patent number: 10508529
    Abstract: Injection fluids formed of reverse emulsions and related methods of forming and using reverse emulsions for cavity control in solution mining. The reverse emulsion can reduce the volume of oil required to create an oil pad at the roof of a solution mining cavern in order to prevent vertical leaching and cavern collapse. The reverse emulsion can be formed from an emulsifier, a brine solution and oil. The emulsifier concentration can range from about 1% to about 5% by weight of the reverse emulsion. The emulsifier and the oil can be combined to form an oil/emulsifier mixture, wherein the oil/emulsifier mixture is combined with the brine solution to form the reverse emulsion. The oil/emulsifier mixture can be from about 1% to about 5% by weight of the reverse emulsion.

  • Patent number: 10429372
    Abstract: A method for measuring liquid-rock and liquid-liquid interfaces including performing at least one measurement technique proximate a subterranean rock sample and an interfacial liquid hydrocarbon fraction, where a liquid hydrocarbon fraction and the subterranean rock sample are combined to exhibit a first interface between the liquid hydrocarbon fraction and the subterranean rock sample, producing the interfacial liquid hydrocarbon fraction. The method includes performing at least one measurement technique proximate the interfacial liquid hydrocarbon fraction and a brine solution, where the liquid hydrocarbon fraction and the brine solution are combined to exhibit a second interface between the liquid hydrocarbon fraction and the brine solution, and where the measurement techniques result in measurements of the interfacial liquid hydrocarbon fraction at macro, micro to nano, nano to sub-nano, and sub-nano scales, and result in measurements of the second interface at macro and micro to nano scales.
