  • Patent number: 10563492
    Abstract: A method of electrically enhancing oil-recovery from an underground rock formation comprising an oil-bearing reservoir is herein detailed. According to the method a controlled electrical charging potential between two or more electrically conductive elements is imposed for a charging time sufficient to cause a capacitive charging of the rock formation, the charging being followed by lowering or maintaining the charging potential below 40 mV per running meter between the conductive elements; during oil withdrawal. Further, a capacitor charging pump having feedback means for use with the method is detailed.

  • Patent number: 10443367
    Abstract: The present disclosure describes methods and systems for fracturing geological formations in a hydrocarbon reservoir. One method includes forming a borehole in a hydrocarbon reservoir from a surface of the hydrocarbon reservoir extending downward into the hydrocarbon reservoir; transmitting an electromagnetic (EM) wave through the borehole: directing at least a portion of the EM wave to rocks at a location below the surface in the hydrocarbon reservoir; and fracturing the rocks at the location below the surface in the hydrocarbon reservoir by irradiating the rocks around the borehole using at least the portion of the EM wave, wherein irradiating the rocks elevates pore-water pressure in the rocks causing fracturing of the rocks.

  • Patent number: 10360282
    Abstract: A method and system for evaluation of a hydrocarbon-bearing shale formation employs a data processing system that defines a response model that relates first data representing measured petrophysical properties of the shale formation at a given location to second data representing volume fractions for a particular set of formation components at the given location. The first data includes hydrogen index at the given location, and the particular set of formation components of the second data include a number of mineral components and a number of hydrocarbon-bearing components. The hydrocarbon-bearing components include at least one kerogen component. A computation solver processes the response model along with the first data to solve for the second data. The solved second data representing the volume fraction of the at least one kerogen component is processed to derive at least one ratio that is indicative of kerogen maturity at the given location.

  • Patent number: 10358901
    Abstract: A carbon dioxide to hydrocarbon conversion device and method are disclosed. A partially produced hydrocarbon subterranean reservoir comprising residual hydrocarbons is provided. A carbon dioxide source is provided, positioned on a surface proximate to the reservoir. A surface mounted high-pressure fluid injector system connecting the carbon dioxide source and the reservoir is provided. A backflow preventer is disposed in-line between the injector system and the reservoir. The injector system injects a catalyst-free feed stream, comprising carbon dioxide, into the reservoir up to an operating pressure. The backflow preventer maintains the operating pressure in the reservoir and sequesters the feed stream in the reservoir. The sequestered carbon dioxide reacts with water and at least a portion of the residual hydrocarbons over a time period to produce additional hydrocarbons. The water is present in the reservoir, provided by the feed stream, or both.
