  • Patent number: 11840913
    Abstract: A method for stimulation of a hydrocarbon-bearing formation includes inserting a perforating tool and an acidic composition into a wellbore. An outside surface of the tool is pre-treated prior to downhole insertion with a grease containing a first corrosion inhibitor adapted minimize corrosion by exposure of the tool the acidic composition for a duration of the stimulation process. The acidic composition further comprises a second corrosion inhibitor that reacts with the first corrosion inhibitor to generate a corrosion protective layer onto the outside surface of the tool. The method further includes perforating the wellbore with the tool, allowing the acidic composition to come into contact with the perforated area of the wellbore, removing the tool from the wellbore; and initiating the stimulation of the perforated area using a stimulation fluid.

  • Patent number: 11834939
    Abstract: The proposed technology relates to treatment of intervals of a productive formation, using a proposed device that is lowered into a wellbore to the depth of an interval, working fluid is admitted to the device's inner cavity below a lower through packer, supplied to a tubing string, through packers are activated, the wellbore annulus is isolated, the well casing is perforated, and the packers are deactivated. The device is lowered to a position between the packers, and is fixed by an anchor. Access of working fluid below the lower packer is cut off, and a hydraulic fracturing fluid is supplied, hermetically isolating the space between the packers. The device is then transferred to the next interval. The device includes the tubing sting, collar finder, upper through packer, hydraulic fracturing port, lower through packer, anchor and perforator. The technology prevents premature activation of the perforator, vibrations and damage to the packers.

  • Patent number: 11821309
    Abstract: Systems and methods include a method for determining perforation cluster points of a reservoir. A rock type of a geological formation of a reservoir is determined using petrophysical data. The transmissible sublayers of the reservoir are determined by grouping the petrophysical data into different subset transmissible layers based on cut-off criteria. Net transmissible reservoir footage for the transmissible sublayers are generated based on averages of parameters for minimum and maximum measured depths. Potential stages for the reservoir are determined using a conditional formatting on the transmissible reservoir footage. Potential perforation cluster points selected based on the potential stages for the reservoir are received from input of an engineer.

  • Patent number: 11781058
    Abstract: A process for consolidating sand, proppant and other suspended particles present in a subterranean reservoir using an aqueous emulsion particle consolidation system is described. Surfactants with cloud points at or below the reservoir temperature are used to make a low viscosity aqueous external emulsion system with resin and curing agent as the internal phase. As the surfactant reaches its cloud point, it loses its emulsification ability and releases the resin and curing agent to consolidate the sand. The aqueous phase of the system then functions as a spacer to maintain the permeability needed for oil and gas production without additional post flush required.

  • Patent number: 11781409
    Abstract: A formation-fracking system has an gas/fluid accumulator, one or more pumps for pumping a fracking fluid, a fracking string extending to a subterranean formation and defining a fracking channel and a circulation channel, a valve subsystem coupling the pumps to the gas/fluid accumulator and the fracking string, and a bypass valve in fluid communication with the fracking channel and a fracking section. The valve subsystem alternately transitions between a first state for directing fracking fluid from the pumps and the gas/fluid accumulator to the fracking channel to create a kinetic-energy surge, and a second state for directing fracking fluid from the pumps to the gas/fluid accumulator for storing energy therein and for fracturing the formation using the kinetic-energy surge. The bypass valve enables a bypass channel fluidly connecting the fracking channel to the circulation channel in the first state and abruptly disables the bypass channel in the second state.
