Abstract: A method for jarring allowing the operator to selectively control the jarring force while the tool is downhole and a powered bidirectional mechanical jar therefor, is disclosed. The jar includes a housing, an anvil fixed within the interior the housing, first and second hammers movably disposed within the housing at obverse sides of the anvil, first and second springs disposed to urge the hammers towards the anvil, and a rod with a radial catch that selectively engages and disengages the hammers so as move the hammers to compress the springs and thereafter release the hammers to be accelerated against the anvil. A actuator operates the catch. By controlling the movement of the rod, the spring compression and resultant jarring intensity can be controlled. A stroker tool may be provided to move the rod.

Abstract: The disclosure provides a downhole anchoring apparatus for use in a downhole tool. An example downhole anchoring apparatus may include a housing with a hub provided within the housing. The hub may be arranged to rotate in a bi-directional fashion about a longitudinal axis. The downhole anchoring apparatus may also include a deployment linkage. The deployment linkage may be coupled to the hub by a hinge so that when the hub is rotated in a first direction, a distal end of the deployment linkage is extended radially outward from the central axis, and when the hub is rotated in a second direction, the distal end of the deployment linkage is retracted toward the central axis.

Abstract: A process for manufacturing a perforation gun casing includes providing a perforation gun housing that has a wall of nominal thickness and at least one scallop. Each scallop is a portion of the wall having a reduced thickness relative to the nominal wall thickness. The process also includes applying a selective annealing process to the perforation gun casing. The selective annealing process affects the material properties of the scallop but generally does not substantially affect the material properties of the portions of the wall having a nominal thickness.

Abstract: A modular, mechanical percussive hammer assembly may be used with drill strings, wireline cable, and coiled tubing. Rotation of a splined driveshaft by downhole electric, hydraulic or mud motor rotates a downwardly-biased hammer and drill body rotatively captured within a upwardly-biased stationary anvil. A bit is carried by the drill body. The hammer contacts and rotates along a cammed control surface of the anvil as the driveshaft is rotated. Interaction between the cammed control surface and the hammer operated to create an axial impact force that is transmitted to the drill body and drill bit.

Abstract: A linear actuator having a power rod supported by movable supports is disclosed. The movable supports can provide support to the power rod to avoid buckling of the power rod under large compressive forces. The movable supports are designed to move towards (e.g., by a biasing mechanism) a first position that minimizes the unsupported length of the power rod, but are capable of being displaced by the power rod during extension of the power rod. Examples of movable supports include slidable bearings (e.g., axially slidable) or rotating braces (e.g., rotatable form a supporting position to an out-of-the-way position). Examples of suitable biasing mechanisms include springs and spring members. In some embodiments, hydraulic force is used to move the movable supports.
