    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.

  • Patent number: 11767731
    Abstract: A device and method for collecting sample fluids from an underground source which includes sample wells terminating in a corrugated conduit and sieve. The sampling regions for each sample well is separated by a grout or expanding seal barrier. Negative pressure is optionally applied to extract fluids from the underground matrix for sampling. The device can also be used for remediating an environmental contaminant from soil or aquifers. Upon identification of at least one environmental contaminant, a remediation composition is injected into the soil or aquifer using the sampling wells of the device. The remediation fluids can be directed to specific locations by selectively utilizing one or more sampling wells to inject the remediation fluid.

  • Patent number: 11761318
    Abstract: A hydraulic fracturing spread system has modular high-pressure fracturing fluid manifold assemblies which couple to form a large trunk line for collecting and conveying high pressure fracturing fluid toward the well bore. Oil-hydraulic intensifier pump units integrated with the modular manifold assemblies increase the fracturing fluid pressure into the trunk line. The manifold assemblies may be configured differently from one to the other and coupleable horizontally and/or vertically.

  • Patent number: 11761311
    Abstract: A perforation cluster of a longitudinal section of a wellbore is provided. The wellbore is for hydraulic fracturing in a preferred direction of a subsurface surrounding the longitudinal section. The longitudinal section has a longitudinal axis in a longitudinal direction and defining a radial direction about the longitudinal axis. The perforation cluster includes all of the perforations of the wellbore within the longitudinal section. The perforations are separated in the longitudinal and radial directions. Two perforations are adjacent in the longitudinal direction and have a first diameter. They also have respective centers that are aligned in the preferred direction with respect to the longitudinal axis and 180° apart in the radial direction, for initiating fractures through hydraulic fracturing in the subsurface. The remaining perforations have a second diameter smaller than the first diameter.

  • Patent number: 11753917
    Abstract: When a child well is hydraulically fractured near the depleted reservoir volume surrounding a previously produced parent well, it is economically efficient to deliver proppant to the formation volume and fractures not reached by the parent well. A fracture length, which is the distance fluid travels from the child well to the depleted region, is calculated as a function of fracture stage. From identified trends in fracture length, fracture length for future stages can be predicted. Based on predicted fracture length, the slurry or treatment volume to cause well interference can be estimated. Proppant concentration or fracturing stage design can be adjusted so that the well interference volume is larger than the treatment volume and proppant is efficiently delivered to the child well fractures.

  • Patent number: 11739631
    Abstract: Methods and systems for determining reservoir permeability of a subsurface formation and fracture surface area. The method includes creating a first hydraulic fracture and a second hydraulic fracture in a horizontal well, generating a pressure pulse at the first hydraulic fracture, monitoring, using a first pressure gauge the pressure at the first hydraulic fracture, monitoring, using a second pressure gauge, the pressure pulse at the second hydraulic fracture, repeating this test at different locations along the wellbore to evaluate heterogeneity in permeability and variations in fracture surface areas, analyzing pressure and rate data to determine either permeability or fracture surface area by using: analytical/numerical simulation models, or physics-based proxy models inputting pressure front/peak arrival time or peak pressure.
