  • Patent number: 9689220
    Abstract: A setting tool (10) for use in a downhole wellbore is described as having a hydraulic fluid pumping mechanism (78) for providing pressurized hydraulic fluid. A piston mechanism (116) is moveable by said pressurized hydraulic fluid acting upon a portion of the piston mechanism (116). A resetting mechanism (84) is provided which when operated releases the pressurized hydraulic fluid from acting upon said portion of the piston (116) and which results in the resetting of the setting tool (10). In addition, a method for resetting a setting tool (10) is described including the steps of: (i) running the setting tool (10) downhole; (ii) actuating the setting tool (10) and thereby deploying an apparatus (203) downhole; (iii) retrieving the setting tool (10) to surface; and (iv) bleeding off pressure to reset the setting tool (10).

  • Publication number: 20140262317
    Abstract: A surface drivehead drives a downhole pump by rotating a rod string at the surface. The downhole pump can be connected downhole to the rod string via a downhole latching mechanism. The surface drivehead has an assembly that can move the rod string upwards or downwards along an axis to either increase or decrease rod string tension. During rod string rotation, rod tension is monitored. If rod string tension changes during rotation, the surface drivehead can automatically compensate by moving the rod string upwards or downwards along the axis to either recapture or eliminate tension. In this way, the surface drivehead can maintain a substantially constant rod string tension to drive the downhole pump at high speeds.

  • Patent number: 8230947
    Abstract: A method for selecting a drilling motor for rotating a drill bit relative to a drill string made up of casing accounts for a tendency for the casing to elongate as the internal pressure increases. The increase in pressure in the casing string increases the weight on the drill bit, the amount of which may be calculated based on the size and type of the string of casing. The ratio of bit torque over the weight on the bit may be assumed to be a constant number based on empirical measurements or a theoretical model. The increase in the weight on the drill bit can be expressed in terms of the bit torque versus the casing pressure, which is a linear slope. This linear slope may be compared to the delivery torque of candidate motors.

The apparatus includes a rotating tool and a driving motor indirectly suspended on coiled tubing. The apparatus also includes a carriage connected to the motor adapted to absorb torques that occur during use. The carriage is connected to the coiled tubing via a swivel coupling such that a tensile force on the coiled tubing provides an advancing force for the tool and motor.

  • Patent number: 6953086
    Abstract: A traction apparatus (1) for propulsion along a bore comprises first and second traction members (6) having outwardly extending legs (14). A propulsion system for operating the traction members (6) comprises a turbine-driven shaft (7) which drives the traction members (6) by way of bearing members (15). In a first phase, one of the legs of the first traction member is moved in one direction whilst in contact with the traction surface to impart the propulsion force at the same time as one of the legs of the second traction member is moved in opposite direction whilst out of contact. In a second phase one of the legs of the second traction member is moved in said one direction whilst in contact with the traction surface to impart the propulsion force at the same time as one of the legs of the first traction member is moved in opposite direction whilst out of contact.

  • Patent number: 6659203
    Abstract: A lockable motor assembly (1) for use in a well bore comprises a PDM motor (2) having a rotor (4) and a stator (3). A locking member (12) has a splined projection (13) which is received within a splined recess (14) of the rotor and external splines (15) which mate with splines provided on a sub (5) connected to the stator. The components are held in this configuration by a shear ring (23) until the fluid pressure within a chamber (28) defined between the locking member (12) and the sub (5) is sufficient to cause the shear ring to shear. The locking member (12) may then move out of the engagement with the rotor to free the motor for operation. The locking member is held in this position by a ratchet mechanism (35).

  • Patent number: 6550534
    Abstract: A fluid powered downhole vibration tool used in a well bore wherein fluids are pumped from the surface into a formation through the well bore. The tool includes a fluid powered motor located within the well bore. The fluid powered motor is in communication with the fluids pumped from the surface. In one embodiment, an actuator coupling is rotated by the fluid powered motor. A seismic mass is rotated in the well bore by the actuator coupler, the seismic mass engaging the well bore and causing vibration of the well bore.

  • Patent number: 6460616
    Abstract: A traction apparatus (1A) includes at least one traction member (51) when engages a surface (10A) against which traction is to be provided. The traction member can move relatively freely in one direction over the surface but has high resistance to movement in the other direction. The apparatus can be made to move by having a number of traction members (51-56) which move or oscillate relative to each other. There are preferably a large number of traction members which are in the forms of bristles in a brushlike part of the apparatus. The apparatus is suitable for use in down-hole tools. The bristles are bent in a first direction by being constrained in a hole facilitating movement in the opposite direction but preventing movement in the first direction.
