  • Patent number: 9617816
    Abstract: A method and system for retrieving a fracturing ball in a wellbore casing. The system includes a wellbore retrieval tool comprising a tool body that is inserted into and transported along the wellbore casing. The tool is sized and configured to trap and hold the fracturing ball. When a hydraulic lock happens in the wellbore casing, the retrieval tool is lowered in a vertical section and the ball is flowed back along a horizontal section and captured by a trap in the retrieval tool. The retrieval tool may also be run in conjunction with a setting tool with a ball-in-place fracturing plug. In case of the hydraulic lock, the injection is tested following perforation with the retrieval tool still a location proximal to the ball, and the ball is immediately retrieved.

  • Patent number: 9506321
    Abstract: A sliding sleeve opens with a deployed ball. The sleeve has a seat disposed in the housing, and the seat has segments biased outward from one another with a C-ring or other biasing element. Initially, the seat has an expanded state in the sliding sleeve so that the seats segments expand outward against the housing's bore. When an appropriately sized ball is deployed downhole, the ball engages the expanded seat. Fluid pressure applied against the seated ball moves the seat into the inner sleeve's bore. As this occurs, the seat contracts, which increases the engagement area of the seat with the ball. Eventually, the seat reaches the shoulder in the inner sleeve so that pressure applied against the seated ball now moves the inner sleeve in the housing to open the sliding sleeve's flow port.

  • Patent number: 8844634
    Abstract: A downhole circulation sub or valve includes a tubular housing with an outer port and a valve piston slidably disposed in the housing. A primary fluid flow path extends through an inner flow bore of the housing and valve piston. In a first position, the valve piston isolates the outer port to prevent fluid communication between the inner flow bore and a well bore annulus. In a second position, the valve piston is moved to obstruct the inner flow bore and expose the outer port to the inner flow bore and allow fluid communication between the inner flow bore and the well bore annulus. An indexing mechanism is coupled between the housing and the valve piston to guide the valve piston between the first and second positions. The indexing mechanism may include a rotatable component.

  • Patent number: 7677304
    Abstract: A downhole valve has a flow tube hydraulically actuated to open and close a flapper. The flow tube moved to a first position closes the flapper to restrict flow through the valve. The flow tube moved to a second position opens the flapper. A passable no-go device disposed in the valve permits or restricts mechanical passage through the valve in response to the position of the flow tube. The apparatus has a support and one or more dogs supported in windows of the support and biased by springs. The flow tube in the first position pushes the dogs to an extended position that restricts mechanical passage through valve so that a tool cannot be passed through the valve while the flapper is closed. When the flow tube is in the second position, however, the dogs retract so the tool can be passed through the valve while the flapper is open.

  • Patent number: 7284606
    Abstract: A tool for multiple purposes features one ore more dogs that can engage a collar groove or restriction sub in the wellbore. The dogs are extendable through a sleeve biased in opposed directions and are supported from a mandrel. The dogs can retract into mandrel grooves to clear restrictions on the trip into the well. On the way up to a collar that has just been passed, the dogs engage and an upward pull on the mandrel displaces fluid through a restriction to allow enough time to get a meaningful surface signal of the overpull force. Thereafter, the applied force can be reduced as the dogs release at a lower applied force to reduce the slingshot effect. The tool can be inverted and used to keep a constant force on a bottom hole assembly during offshore drilling where a heave compensator is employed.

  • Patent number: 5775421
    Abstract: A fluid loss device has a housing, a seal assembly, a running tool, and a plug. The housing of the fluid loss device is placed in a production string before a well bore is completed. The plug is attached to the running tool, and the running tool is attached to a wash pipe.The fluid loss device is activated by lifting the wash pipe and the running tool, thereby engaging the plug with the seal assembly, engaging the seal assembly with the housing, and severing the plug from the running tool. Activation of the fluid loss device inhibits fluid communication through the fluid loss device and reduces damage to the well structure behind the fluid loss device while completion operations are performed in other areas of the well bore.The fluid loss device is deactivated by forcing the plug through the fluid loss device with mechanical force or pressure, or by chemically eroding the diameter of the plug until the plug passes through the fluid loss device.
