  • Patent number: 11713647
    Abstract: A technique facilitates control over flow of fluid in a variety of well applications and other applications. A flow control device is used to automatically control flow of fluids based on viscosity of the fluids. For example, the flow control device may be used to automatically allow flow of oil while blocking flow of gas and/or water. According to an embodiment, the flow control device comprises a production circuit and a metering circuit. The production circuit and the metering circuit cooperate to allow flow of a well fluid with a first viscosity and to block flow of well fluid when the well fluid has a different viscosity, e.g. relatively lower viscosity.

  • Patent number: 11643889
    Abstract: The debris catch provides a strainer located downstream of a rotating control device (RCD) within a flow line. The strainer is located between the RCD and at least one protected component. The strainer limits the debris and other junk that flows to protected components located downstream of the strainer. A first sensor and a second sensor detect the pressure differential between a location before the strainer and at the strainer. The two sensors detect a clog in the strainer. The strainer is removable through an access outlet for clearing the clog and reinstalling a strainer for continued drilling operation. A purge valve located in the system also allows clearing of the strainer by releasing the debris through a purge outlet located on a pathway separate from the pathway to the protected component.

    Abstract: Wellbore devices for use in filtration, wellbore isolation, production control, lifecycle management and wellbore construction may include at least a first and a second shape-memory material each having an altered geometric position and each an original geometric position. Each shape-memory material may include a polyurethane material held in the altered geometric run-in position at a temperature below glass transition temperature (Tg), where the Tgs and/or the respective slope changes of the first and second polyurethane materials are different. Once the wellbore device is in place downhole and the first and second shape-memory materials are subjected to temperatures above their Tgs, the materials will deploy and expand to recovered geometric positions at or near their original geometric positions to perform their filtration, isolation, control or other function. These deployments or expansions may occur at different times or rates.

  • Publication number: 20150144328
    Abstract: The disclosed downhole gas and solids separator includes a suspended helical flighting member for efficient downhole separation of both gases and solids from a hydrocarbon production stream. Centrifugal force, provided by the flighting member, accelerates the coalescence of like materials to enhance separation of both gases and solids within the separator. Centrifugal force urges solids to the outer wall of the separator and gases toward the center, where passageways are designed to allow solids to efficiently migrate toward and accumulate at the bottom of the separator while simultaneously allowing gases to efficiently rise out of the separator device.

  • Patent number: 9010417
    Abstract: An assembly of screens made of connected joints with exterior bypasses that span the threaded connections among the joints features common fluid connections for the bypasses adjacent joint threaded ends that are connected with a coupling. A mandrel spans from one joint to the next inside the threaded coupling and is sealed to the respective bases pipes on opposed ends of the coupling. At each end of the mandrel the surrounding base pipe has openings from the common fluid connection where the bypasses terminate to define an annular flow path between pairs of common fluid connections. The bypasses can have slanted gravel outlet passages or no gravel openings at all. The bypasses can span over screen or blank pipe with an option to mount a shroud over the generally parallel bypasses.

  • Publication number: 20150060059
    Abstract: A technique facilitates detection of specific constituents in a well fluid as it is produced from a reservoir. The technique employs a screen assembly having a base pipe and a filter media coupled with the base pipe. An access opening is provided in the screen assembly for insertion of a tracer into a region between the base pipe and the filter media. The tracer is then secured in the region between the base pipe and the filter media. The technique enables selection and application of specific, interchangeable tracers while in the field, e.g. at a well site.

  • Publication number: 20150034301
    Abstract: A well screen for use in a subterranean well can include a loose filter media, a sandstone, a square weave mesh material, a foam, and/or a nonmetal mesh material. A method of installing a well screen in a subterranean well can include dispersing a material in a filter media of the well screen, after the well screen has been installed in the well, thereby permitting a fluid to flow through the filter media. A method of constructing a well screen can include positioning a loose filter media in an annular space between a base pipe and a shroud, so that the filter media filters fluid which flows through a wall of the base pipe.

  • Patent number: RE46286
    Abstract: A downhole mixing tool and method for removing sand and other debris from a wellbore which combines the sand with a treatment fluid so that the sand is lifted to the surface of the well for removal. The tool includes a chamber into which the sand laden fluid is drawn and the treatment fluid is introduced. Ports into the chamber are arranged to provide a pressure drop to draw the sand laden fluid into the chamber and a mixing time within the chamber before sand laden fluid of lower viscosity exits the chamber to travel to the surface. Additional features include blades on the tool for breaking up obstructions prior to being drawn into the chamber and a lubricating line through the tool to introduce lubricating fluid to the blades.
