  • Patent number: 11391128
    Abstract: The disclosure relates to a method for producing heavy oil by generating solvents in situ in the reservoir, an electric heating device is used to heat up the crude oil in the reservoir near the wellbore to the target temperature. Chemical reaction additives are injected into the heating section to meet the preset reaction conditions for the high temperature thermal cracking and aquathermolysis of crude oil, so as to generate light hydrocarbon components and gases. Under the effect of heat and gravity, the light hydrocarbon components and gases rise to the steam chamber. The light hydrocarbons and some gases that move to the vapor-liquid interface of the steam chamber are dissolved in the crude oil to reduce the viscosity of crude oil and increase the production rate of crude oil.

  • Patent number: 10273785
    Abstract: A process for removing hydrate formations from a flowline includes connecting a manifold to the flowline, passing an inert gas across a pair of inlets of the manifold so as to create a reduced pressure across the pair of inlets that is less than a pressure of a fluid in the flowline, opening a valve between the pair of inlets and the flowline so as to expose the pressurized fluid in the flowline to the reduced pressure across the pair of inlets, disassociating hydrates in the flowline by exposure to the reduced pressure across the pair of inlets, and flowing the fluid and the disassociated hydrates from the flowline into the outlet of the manifold and outwardly of the manifold through at least one of the pair of inlets.

  • Patent number: 10260327
    Abstract: A method for remotely controlling services to a well during hydraulic fracturing operations includes generating a high pressure fluid. The high pressure fluid is pumped into a subterranean geologic formation through a wellbore of a first well at a pressure to fracture the subterranean geologic formation. The method also includes performing a service on a second well that is located within a pressure zone defined around the first well and the second well. The method further includes controlling the performance of the service from a remote operations hub located outside of the pressure zone. The pumping into the first well may be performed simultaneously with the service on the second well.

  • Patent number: 10161224
    Abstract: Paraffin deposits from downhole tubing, pumps and valves are removed by hot water and recycling the hot water to allow continual intermittent cleaning throughout the lifespan of the well. Heated water travels down the hollow rod annulus, entering the hollow rod string through ports at the bottom, temporarily heating both strings to melt and mobilized paraffin to enable intermittent pumping paraffin and debris to surface.

  • Patent number: 10150078
    Abstract: An amount of seawater control device controls an amount of seawater supplied to a scrubber that purifies sulfur oxide contained in exhaust gas by bringing the sulfur oxide into contact with seawater. The control device includes a minimum amount of seawater converter which calculates a minimum amount of seawater necessary for an absorption reaction of the sulfur oxide by the seawater, an amount of seawater correction converter which calculates a corrected amount of seawater which is an amount of seawater at which the sulfur oxide contained in the exhaust gas discharged into atmosphere from the scrubber is equal to or less than a set variable, a summing element which calculates a set amount of seawater by summing the minimum amount of seawater and the corrected amount of seawater, and a pump control device which implements control such that seawater corresponding to the set amount is supplied to the scrubber.
