Patent number: 11821309Abstract: 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.Type: GrantFiled: February 23, 2021Date of Patent: November 21, 2023Assignee: Saudi Arabian Oil CompanyInventors: Abu Mohammed A. Sani, Maytham I. Ismail, Mohd Azizi Ibrahim, Clovis Satyro Bonavides

Patent number: 11787997Abstract: Provided is a method that may include introducing into a wellbore as a single stage treatment a composition that may include a fluid formulation that is a water-in-oil emulsion having an organic phase and an aqueous phase, the aqueous phase dispersed in the organic phase; maintaining the wellbore by shutting-in the well; and hydraulic fracturing the wellbore. The composition may contain a chelating agent and may interact with an oil-based sludge or filter cake, which may contain barite, at a target zone, allowing the composition to remove a portion of the oil-based mud sludge or filter cake.Type: GrantFiled: March 21, 2022Date of Patent: October 17, 2023Assignee: SAUDI ARABIAN OIL COMPANYInventors: Abdullah Al Moajil, Waddah H.

Patent number: 11781058Abstract: 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.Type: GrantFiled: September 1, 2022Date of Patent: October 10, 2023Assignee: OIL CHEM TECHNOLOGIESInventors: Paul Daniel Berger, Christie Huimin Berger

Patent number: 11781409Abstract: 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.Type: GrantFiled: April 15, 2020Date of Patent: October 10, 2023Assignee: THE ANDERS FAMILY LIVING TRUSTInventor: Edward Anders

Patent number: 11767731Abstract: 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.Type: GrantFiled: August 23, 2021Date of Patent: September 26, 2023Assignee: En RX Chemical, Inc.Inventors: Lance I.
