  • Publication number: 20150068730
    Abstract: A down hole pressure isolation tool is placed in a pipe string and includes a pair of pressure discs having one side that is highly resistant to applied pressure and one side that ruptures when much lower pressures are applied to it. The weak sides of the pressure discs face each other. In some embodiments, an upper disc is mounted for movement and restrained by a shearable connection. Upon the application of pressure to the tool, the connection shears allowing the upper disc to move into and collide with the lower disc thereby fracturing both discs and allowing pressure communication across the tool. In another embodiment, spurs carried by a sleeve fracture an upper disc in response to pressure delivered to an upper end of the tool.

  • Patent number: 8955606
    Abstract: Sealing devices for use in a wellbore to seal a leak path through an inner wall surface of the wellbore comprise a mandrel, an expandable element, and a shape deforming sealing element. Expansion or inflation of the expandable element moves the shape deforming sealing element from its run-in shape to its set shape. A stimulus, such as a change in temperature, acts upon the shape deforming sealing element facilitating the shape deforming sealing element changing shape. Removal of the stimulus causes the shape deforming sealing element to remain in the set shape. Thereafter, the mandrel and expandable element can be removed to leave only the shape deforming sealing element within the wellbore to seal the leak path.

The shear release features a lock that limits relative movement so that a shear member can be defeated but without a release. A dog limits relative movement in a wider groove where dog movement in the groove allows a shock absorbing feature to act to cushion the release as the shear member breaks. The relative movement is reversed to let a retaining ring drop out of the way into a groove that comes into alignment with it. The relative movement is reversed again to pull a sleeve out from under gripping collets that have previously failed to release and the tool releases from that point on the same way as the control line actuated release.

A sealing ball is carried with the packer into the well by a setting tool. The movement of the sealing ball away from the ball seat is limited by isolation of the sealing ball from the lower well. A rod is disposed through the downhole tool contacting the plug. The rod is partially disposed in the ball seat, preventing the sealing ball from sealing. When the packer is set, flow within the well is isolated, thereby allowing treatment of the well above the packer. With the application of sufficient pressure, the sealing ball applies force to the rod which shears the plug from within the tool. The tool is converted to a standard frac plug.

  • Publication number: 20110232899
    Abstract: A downhole tool for use in a well is configurable as a frac plug, a caged ball frac plug or a bridge plug. The tool has a mandrel with a threaded neck. The mandrel has an expandable sealing element disposed thereabout. An adapter, which may be selected from multiple configurations of adapters, is threaded to the neck of the mandrel. The adapter may comprise a sleeve, or a cap with one open end and one closed end. The adapter has threads on an outer surface thereof to which a threaded setting mandrel may be attached. The setting mandrel when actuated will move the tool to a set position in the well and once the tool is moved to the set position the threads on the adapter will shear so that the setting mandrel may be retrieved. The tool will thus remain in the hole and will act as either a frac plug, a caged ball frac plug or a bridge plug depending upon the configuration of the selected adapter.

  • Publication number: 20110209867
    Abstract: Parts that need to be retained against relative movement are held with at least one collet that is captured in a groove with sleeve that acts as a piston. The piston is exposed to tubing pressure on opposed ends to be in pressure balance despite variations of pressure in the tubing. When it is desired to allow relative part movement to actuate the tool, one of the ports to the piston is isolated from the other and pressure drives the piston in a downhole direction. This releases the collet and drives a sleeve in an opposite direction to actuate a tool. The parts can be optionally rotationally locked.

  • Patent number: 7963322
    Abstract: Devices and methods for setting a packer inside a wellbore with little appreciable reduction of the useable area of the wellbore. The outer casing or liner of the wellbore contains one or more integrated casing coupler joints having an increased diameter chamber portion. A large bore packing element is carried within the increased diameter chamber portion. The packing element may be selectively actuated to form a seal against an interior tubular member. Because the packing element is located within the chamber portion of the casing coupler, the packer may be set while saving useable cross-sectional area within the casing.

  • Patent number: 7757756
    Abstract: A bridge plug comprises an axially compressible cylinder having plural expansion sleeves. A mandrel extends axially through the cylinder, and has a threaded portion engaged with the cylinder, such that rotation of the mandrel causes compression of the cylinder. A setting tool comprises a housing containing a motor and a drive shaft driven by the motor. The setting tool is configured to be removably coupled to a bridge plug with the drive shaft drivingly coupled to the bridge plug's mandrel, such that operation of the setting tool motor causes compression of the bridge plug. The setting tool is used to lower a bridge plug within a well casing, and to compress the bridge plug causing, outward protrusion of sealing members of the bridge plug to set the bridge plug in place. Cement may be applied above the set bridge plug to form an easily drillable seal.
