  • Patent number: 9970259
    Abstract: A dump valve arrangement for a fracking tool coupled to a length of coil tubing includes an axially displaceable inner mandrel which cooperates with a valve arrangement to allow for releasing fracturing fluid through the central bore of a fracturing tool to an outlet port positioned at the bottom of the tool string. Displacement of the inner mandrel is effected as a result of the normal sequence of operation of the fracturing tool set.

  • Publication number: 20150083419
    Abstract: A fracturing valve comprising a tubular mandrel having a through bore continuous with a tubing string, and a frac window through the side of the tubular mandrel. An outer sleeve is radially disposed around the tubular mandrel. The outer sleeve includes a sleeve port in a sidewall. The tubular mandrel slides relative to the sleeve by application and release of set down weight on a coiled tubing string. When the valve is closed, there is no fluid communication from the tubing string out of the frac window. When the valve is open, fluid communication from the tubing string is enabled. The valve may be installed in a downhole tool having a perforation device. The tool string can be used with one sealing element as the tool is pulled up the hole isolating lower perforations, or with two sealing elements to allow pin-point treatments isolating perforations both up and downhole.

  • Patent number: 8985216
    Abstract: A sliding sleeve has an associated shock absorber to limit shock loading to the shifting apparatus when the end of travel is reached. An adjacent sleeve defined an annular cavity in a manner that does not reduce the drift dimension of the shifting sleeve. The cavity has a fluid in it and the movement of the shifted sleeve causes the movement of the shock absorber sleeve to reduce the fluid volume in the annular cavity. The volume reduction forces fluid through a restriction to regulate the speed of the sliding sleeve as a travel stop is reached. The fluid can be a gas, an incompressible fluid or grease. The restriction can be temporarily covered such as with a rupture disc. Room to compensate for thermal expansion can be provided in the annular space.

  • Patent number: 8967269
    Abstract: A tubular valving system includes, a tubular, a seat, a sleeve movably engaged with the seat between at least a first position, a second position and a third position, a release member between the sleeve and the seat that maintains the sleeve relative to the seat in the first position until release thereof, a biasing member configured to urge the sleeve from the second position toward the third position, and a flapper sealingly engagable with the seat. A first threshold pressure against the seated flapper causes release of the release member allowing the sleeve and the seat to attain the second position. A subsequently drop in pressure against the seated flapper below a second threshold level allows the biasing member to move the sleeve relative to the seat to the third position thereby unseating the flapper from the seat and preventing the flapper from again seating with the seat.

  • Patent number: 8881824
    Abstract: A tool string carrying an external tool, such as a liner hanger, on a release mechanism is lowered into the wellbore. Interlocking lugs and J-slot profile, defined between the exterior surface of the mandrel and interior surface of the release mechanism, allow relative movement of release mechanism and mandrel without releasing the release mechanism. The relative movement allows mechanical operation of a valve or other tool positioned below the release mechanism. Weight-down and rotation of the tool string and mandrel actuates the lower valve assembly by turning a sleeve into alignment with cooperating members of the mandrel. The sleeve, no longer constrained, moves longitudinally in response to a biasing mechanism. Movement of the sleeve allows closure of the valve. After actuation of the valve tool, further weight-down releases the release mechanism from the carried tool.

  • Publication number: 20130075101
    Abstract: A dump valve arrangement for a fracking tool coupled to a length of coil tubing includes an axially displaceable inner mandrel which cooperates with a valve arrangement to allow for releasing fracturing fluid through the central bore of a fracturing tool to an outlet port positioned at the bottom of the tool string. Displacement of the inner mandrel is effected as a result of the normal sequence of operation of the fracturing tool set. The valve arrangement is in a closed position during both the insertion and positioning of the tool string.

  • Patent number: 8356669
    Abstract: A well system can include an inflow control device which resists flow into a tubular string. A selection from among multiple different flow resistances through the inflow control device can be performed in response to pressure manipulation. An inflow control device can include a piston which is displaceable to at least two positions. Flow through the inflow control device is permitted at a certain flow resistance when the piston is at one position, and flow through the inflow control device is permitted at a greater flow resistance when the piston is at another position. Fluid which flows through the inflow control device can be constrained to flow through an increased number of flow restrictors in response to displacement of the piston from the first to the second position.

  • Patent number: 8302692
    Abstract: A sand slurry valve that includes a mandrel within a housing and a seal assembly connected to the mandrel. A portion of the housing includes a seal bore. The mandrel is movable within the housing such that the seal assembly may be positioned within the seal bore. The mandrel includes a flow passage adapted to provide rotational fluid flow through the housing prior to the seal assembly being moved into the seal bore. The seal assembly may include a seal, a first backup ring, and a second backup ring with the second backup ring positioned between the seal and the first backup ring. The rotational flow through the housing may help to protect the seal from being damaged by particles carried within the flow. The first backup ring may have a harder durometer measurement than the second backup ring, which may have a harder durometer measurement than the sealing element.

  • Patent number: 8291982
    Abstract: A completion tubular is placed in position adjacent the zone or zones to be fractured and produced. It features preferably sliding sleeve valves that can assume at least two configurations: wide open and open with a screen material juxtaposed in the flow passage. In a preferred embodiment the valve assembly has three positions, adding a fully closed position to the other two mentioned. After run in, the valves can be put in the wide open position in any order desired to fracture. After fracturing, the valves can be closed or selectively be put in filtration position for production from the fractured zones in any desired order. Various ways are described to actuate the valves. The tubular can have telescoping pistons through which the fracturing can take place if the application calls for a cemented tubular.

  • Patent number: 8215399
    Abstract: A multi-string well has an electric submersible pump (ESP) that can be removed without killing the well. A slotted liner is sealingly secured externally to casing and internally to a guide string that remains in the wellbore when the ESP is removed. A ported sub is part of the guide string and a concentric screen that can have instruments that moves relatively to the guide string can selectively allow flow in an annulus between them and to the ported sub or that annulus between the guide and concentric strings can be blocked off by manipulation of the concentric string to close the ported sub. With the lower portion of the well now blocked off, the wellhead can be removed so that the ESP can come out with the production string. The device has particular application to steam assisted gravity drainage (SAGD) systems as well as other downhole applications.
