    摘要: A downhole tool includes a housing defining an axial bore. The downhole tool also includes a piston positioned at least partially within the housing. The piston is configured to actuate from a first piston position into a second piston position at least partially in response to a pressure differential. The downhole tool also includes a locking mechanism positioned at least partially within the housing. The locking mechanism is configured to actuate from a first locking mechanism position into a second locking mechanism position at least partially in response to the pressure differential while the piston is in the second piston position. The downhole tool also includes a disk positioned at least partially within the housing. The disk prevents fluid flow through the axial bore. The disk is configured to break at least partially in response to the pressure differential while the locking mechanism is in the second locking mechanism position.

    摘要: Apparatus and methods are provided relating bottom hole assemblies (BHA) electrically connected to a wireline. The BHA adapted for manipulating one or more target sleeve valves spaced along a wellbore having a sleeve shifting tool and a sealing element. The system can be shifted open by fluid pressure or electrically actuated stroking and closed by electrically actuated stroking. Methods of deploying a BHA for fracturing operations connected by wireline in a casing of a wellbore are also provided including obtaining real time sensor data from the BHA.

    摘要: A Bottom Hole Assembly (BHA) tool and methods of downhole fluid management are disclosed. The BHA is deployed on a conveyance string to access a completion string and forming a tool annulus therebetween. A first assembly having a first bore fluidly connected to the conveyance string. A second assembly supports a packer for releasably sealing to the completion string, and a third assembly supporting a packer actuator thereon, the second assembly telescopically movable within the third assembly for forming a resettable packer releasably sealable to the completion string. A bypass valve is formed between the first and second assembly. Closing of the bypass valve directs fluid through a treatment port uphole of the resettable packer to the tool annulus and opening of the bypass valve bypasses fluid about the resettable packer. The packer actuator can further comprise an anchor for releasably anchoring to the completion string.

    摘要: A flow-actuated pressure equalization valve, for use with a downhole tool such as a treatment tool, for use in stimulating a subterranean formation. The equalization valve allows the pressure of treatment fluid above and below an isolation device to be equalized so the treatment tool can be moved. The valve can be closed when fluid flow exceeds a certain threshold and the treatment tool is set in the wellbore. While running in or pulling out of hole, the valve will not close regardless of the rate of fluid flow. The valve can be opened by stopping fluid flow and then bleeding off pressure above the isolation device, or by pulling up on the treatment tool.

    摘要: A frac plug mandrel assembly has an inner core that permits flow that is surrounded by a thin wall tube that distributes compressive loading, such as that applied by the set sealing element to the core. The core is a cylindrically shaped insert for inside the tube and allows flow until a ball or plug is landed on a seat to close off the flow through the core. The core can have a star pattern with a series of radially extending segments from a solid hub or a cylindrical shape of a honeycomb or other porous structure that has the requisite strength to resist collapse from compressive loading of the set sealing element while still allowing sufficient flow area for fluid displacement.

    摘要: Downhole tools and methods for isolating a wellbore. A downhole tool can include a body having a bore or flowpath formed therethrough, and one or more sealing members disposed therein. The one or more sealing members can include an annular base and a curved surface having an upper face and a lower face, wherein one or more first radii define the upper face, and one or more second radii define the lower face, and wherein, at any point on the curved surface, the first radius is greater than the second radius. The sealing members can be disposed within the bore of the tool using one or more annular sealing devices disposed about the one or more sealing members.

    摘要: A bridge plug with a selectively blocked flow passage is delivered on wireline and pumped down to the desired location and set. A casing pressure test can be performed above the bridge plug while shielding the formation below from excess pressure from the pressure test. To the extent there are producing zones below the bridge plug or adjacent injection wells that could communicate with the borehole, the plug isolates those pressures from below. After the pressure test is completed, a rupture disc is blown in a passage through the bridge plug and flow is then used to deliver completion equipment to a horizontal portion of the borehole and preferably on wireline.
