  • Patent number: 9316074
    Abstract: A lock system works in combination with a mandrel to allow selective operation and disabling of a downhole tool. In the specific situation of a Smart Collet® the tool is locked from being able to find support when engaged to a mating profile as the tool is moved between landing locations. A lower housing features an external dog that in response to rotation takes with it a collet ring with circumferentially oriented fingers. An outer housing cams the collet heads into a respective groove in the mandrel. Reversal of such relative rotation between the upper and lower housings allows the collet heads to spring out of the mandrel groove for the unlocked position. The lock is adapted for use in a variety of tools. The rotation to unlock and then lock is accomplished by dog interaction with shaped internal profiles in a surrounding tubular assembly at strategic locations where needed.

  • Patent number: 8893807
    Abstract: An actuation tool uses a lock that when released allows a moving magnet to move into position to repel another magnet. The repelling force on the second magnet moves it away from a locking position on a stored potential energy system where the release of the potential energy creates kinetic energy to drive an actuation assembly to set the tool. In a preferred application the tool can be a liner hanger. The release device can be a selectively energized electromagnet or a solenoid that shifts at least one magnet into alignment with at least one second magnet so as to defeat the second magnet from effectively storing the potential energy that can set the tool when the lock is defeated.

  • Publication number: 20140048247
    Abstract: A hydraulic jar for delivering impacts downhole. The jarring mechanism includes a cup-type piston that moves through a seal bore. The cup is deformable in response to fluid pressure so that it expands each time it moves through the seal bore to compensate for wear on the lip. Since only minimum interference is required between the piston and seal bore, less material may be used. This reduces the force required to reset the tool, which is particularly advantageous in horizontal wells. The seal bore may be slightly wider at the exit; the cup expands to this exit diameter, ensuring an interference fit as the cup travels back through the smaller diameter entry section. The entry end of the seal bore may include longitudinal grooves. This prevents the piston cup from rupturing by preventing a fluid seal around the lip until the most of cup is inside the seal bore.

  • Publication number: 20130248202
    Abstract: A control mechanism for use with a safety valve adapted to seal a wellbore is described. The control mechanism comprises at least one valve actuator for engaging with the safety valve, the at least one actuator being moveable, in use, between a valve open position in which the safety valve is open and a valve closed position, in which the safety valve is closed. The control mechanism further comprises biasing apparatus adapted to bias the at least one valve actuator to the valve closed position, wherein, in use, the at least one valve actuator extends from the safety valve up to a wellbore wellhead. In one described embodiment, the safety valve is moved between the open and closed positions by movement of the at least one valve actuator with respect to the wellbore.

  • Patent number: 8523543
    Abstract: A pumping assembly includes a well head with a radial flow channel for pumped fluids. A spacer stand is secured to the well head. A hydraulic pump is provided with a housing secured to the spacer stand. The hydraulic pump has a hydraulic ram tied to a reciprocating annular piston having a central bore. When the annular piston moves in an upward direction the hydraulic ram moves toward an extended position extending from the housing. When the annular piston moves in a downward direction, the hydraulic ram moves toward a retracted position retracted within the housing. A polish rod extends up through the central bore of the annular piston and is held in position by a polish rod clamp positioned on top of the hydraulic ram. The polish rod moves with the hydraulic ram.

  • Publication number: 20130199797
    Abstract: A fluid injection device (38) for deployment in a well-bore to control injection of fluid into an oil reservoir, wherein the well-bore has an outer pipe (16) and an inner tube (14) which extends within the outer pipe and is connected at one end to a pressurized fluid supply above the ground. The device includes a control valve arrangement comprising: an inlet (42) for receiving the fluid from the inner tube; an outlet (56) for outputting the fluid outside the inner tube; an inlet valve (44) in a fluid path between the inlet and the outlet; and an actuator (50) associated with the inlet valve which is controllable to switch the inlet valve between its open and closed configurations, such that when the inlet valve is open, the fluid flows from the inner tube, via the inlet, fluid path and outlet to outside the inner tube. A method of controlling injection of fluid into an oil reservoir from a well-bore using such a device is also provided.

  • Patent number: 8469106
    Abstract: A technique facilitates actuating a variety of components in a downhole environment. The technique utilizes displacement based activation of an atmospheric actuation chamber. Activation of the atmospheric actuation chamber may be initiated via a variety of mechanisms, including manipulation of a restraining device, translation of a seal, and/or destruction of a seal. The atmospheric actuation chamber is coupled in cooperation with the corresponding downhole component to enable selective activation of the downhole component.

    Abstract: A method, computer-readable medium and apparatus for delivering a material to a downhole location in a formation is disclosed. A device is operated at a surface location to produce an action at the downhole location related to delivery of the material to the formation. A downhole parameter is measured at the downhole location, wherein the downhole parameter is affected by the operation of the device at the surface location. The downhole parameter is measured using a sensor proximate the downhole location.
