Abstract: A downhole activation assembly for activating a downhole component of a downhole tool positionable in a wellbore penetrating a subterranean formation. The activation assembly includes a housing operatively connectable to the downhole tool, a spring-loaded sleeve, and a ball catcher. The sleeve slidably positionable in the housing, and having a flow channel therethrough and an outer surface defining a chamber between the sleeve and the housing. The sleeve having inlets therethrough about a sleeve end thereof to permit fluid from the flow channel to pass therethrough. The ball catcher slidably positionable in the housing, and having a catcher end engageable with the sleeve end to selectively divert the fluid thereabout and a ball seat therein to receivingly engage a ball passing through the sleeve whereby the ball catcher selectively moves the downhole component between activation positions.

Abstract: A running tool for well drilling operations is carried by a running string into and out of a wellbore. A collet is carried by the running tool, the collet having fingers with a radially expanded position arranged to latch against a wellbore shoulder in the wellbore. The fingers are resiliently and radially contractible. A shear element is carried by the collet, the shear element preventing the fingers from radially contracting to unlatch the running tool while the shear element is intact. If a selected axial force is applied against the shear element, it shears, freeing the collet fingers to retract. The collet may be part of a tool to set and release a liner hanger from engagement with a string of casing.

Abstract: A hydraulic disconnect apparatus is disclosed for disconnecting a pipe string or coiled tubing string from a bottom hole assembly for drilling, work over, or plug and abandonment of oil and gas wells. Disconnection is accomplished by pumping a circulation ball from surface through the pipe or coiled tubing string until it lands on a seat inside the apparatus. Fluid pressure is then applied to shift a piston assembly within the apparatus, thereby allowing a series of balls to retract. The upper and lower portions of the apparatus can then be separated by applying a tensile force to the upper portion.
