  • Patent number: 10781671
    Abstract: A method of controlling fines migration in a wellbore penetrating a subterranean formation, the method comprising: introducing into the wellbore a screen mesh in an unexpanded form disposed of a first tubular member having a body with apertures, the screen mesh comprising a degradable material; expanding the screen mesh; injecting a cement slurry into the wellbore to fill open spaces within the expanded screen mesh; allowing the cement slurry to set forming a set cement that reduces or substantially preventing the passage of formation particles from migrating from the subterranean formation into the wellbore; and removing the degradable material of the screen mesh forming a fluid pathway in the set cement, which allows a formation fluid to flow from the subterranean formation into the wellbore.

  • Patent number: 10774618
    Abstract: A downhole power generator module having a body with one or more couplings that are configured to connect the body to a downhole tool string positioned downhole in a wellbore. An axial passageway is formed through the outer housing and couplings. The power generator module has a pressure-driven electric generator such as a triboelectric or piezoelectric generator positioned within the body. A port in the body enables communication of well fluids from the wellbore to the generator. Pressure changes in the well fluids are communicated to the pressure-driven electric generator, causing it to autonomously generate electric power downhole. The generated power is provided directly to other downhole tools without intervention from the surface.

  • Patent number: 10760376
    Abstract: A pressure control valve for downhole treatment operations includes a valve body including an inlet, an outlet, and a valve seat. A valve assembly is arranged in the valve body. The valve assembly includes a valve member selectively positionable on the valve seat to control fluid flow through the valve body. A piston assembly including a piston and a control fluid inlet is arranged in the valve body. The piston is operatively connected to the valve assembly. The piston is operable to bias the valve member toward a closed configuration upon exposure to a control fluid.

  • Patent number: 10760713
    Abstract: A flexible protector including a protector housing, clearance space defined by the housing the clearance being dimensioned and positioned to preserve flexibility of the housing while isolating a placed device from bending therein upon flexing of the housing. Also disclosed is a resource recovery system including a spoolable conductor, a device disposed in line with the conductor, and a spoolable protector disposed about the device. A method for protecting a device inline in a spoolable conductor including contacting the device with a buttress of a first half protector, securing conductors in the half protector, and interconnecting a second half protector with the first half protector. A method for instrumenting a target environment.

  • Publication number: 20200080398
    Abstract: A mandrel in production tubing within a well has a side pocket with an inlet port for connection to an upper control line segment that extends upward alongside the production tubing. An outlet port is below the inlet port for connection to a lower control line segment extending below the pocket. A filter assembly is lowered through the production tubing into the pocket. A valve at a lower end of the pocket is movable from a closed position closing the outlet port to an open position opening the outlet port. A probe mounted to a lower end of the filter assembly engages and pushes the valve from the closed position to the open position while the filter assembly is being seated in the pocket.
