摘要： 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.

摘要： An compact instrumented downhole coupling that includes a carrier and a set of sensors and electronics that are installed within the carrier. The carrier is a tubular structure having couplings at each end and a bore extending through the carrier from the first end to the second end, forming a carrier wall between the bore and the exterior surface of the carrier. The bore and couplings are offset from a central axis of the carrier (the axis of the cylindrical outer surface of the carrier), resulting in a thicker portion of the carrier wall on one side of the carrier. Cavities are formed (e.g., by drilling holes) within the thicker portion of the carrier wall. One or more sensors and corresponding electronics are then positioned within the cavities, so that the carrier wall itself forms a housing for the sensors and electronics.

摘要： 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.

摘要： A fluid injection valve comprising: a valve body including a first end having a first opening, a second end having a second opening, an outer surface and an inner surface defining a fluid pathway extending between the first end and the second end; a seat arranged along the fluid pathway; a restriction device selectively abutting the seat; a biasing member arranged in the fluid pathway abutting the restriction device; urging the restriction device against the seat; a biasing element having a biasing force urging the biasing member against the restriction device; and a magnet functionally connected to the biasing element, the magnet selectively forcing the biasing member axially outwardly of the restriction device against the biasing force.

摘要： A pressure compensator including a housing, an electroactive polymer (EAP) disposed in the housing and defining a volume therein, the volume being changeable upon application of an electric signal. A method for managing pressure in a tool including applying an electrical signal to the pressure compensator and changing a shape of the EAP to change the volume of the compensator whereby the pressure in the tool is altered. A borehole system including a borehole in a subsurface formation, a string in the borehole, a pressure compensator disposed within or as a part of the string.

摘要： An injection valve including a housing, a fluid channel in the housing, and a check valve disposed in the housing and responsive to fluid pressure in the channel to move the check valve in a direction opposite the direction of fluid flow through the channel. A method for injecting fluid into a volume including pressurizing a fluid to be injected, conveying the pressurized fluid to a space about a check valve between a check valve nose and a stem seal; and moving the check valve in a direction opposite a direction of injection fluid flow. A borehole system including a borehole in a subsurface formation, a string disposed within the borehole, and an injection valve disposed within or as a part of the string.

摘要： An embodiment of a downhole device includes an elongated body configured to be deployed in a borehole in an earth formation, the borehole including a borehole fluid. The device also includes a propulsion system attached to the body and configured to move the device through the borehole. The propulsion system includes one or more rotor blades configured to generate thrust using the borehole fluid. At least part of the one or more rotor blades is disposed external to the elongated body.
