Abstract: The present invention provides a method and an apparatus for use in a wellbore tool. The apparatus includes a body (115) and a sliding member (155), wherein the sliding member and a mechanical portion (250) moves between a first position and a second position. A valve assembly (210) causes the sliding member and mechanical portion to shift to its second position at a predetermined flow rate of fluid through the body. The invention also provides an apparatus for a downhole tool that includes a mandrel and a sliding member disposed on the mandrel. The sliding member including a plurality of fingers (285) and a plurality of heads (275), wherein the plurality of fingers are slideably recessed within a plurality of longitudinal grooves (355). The invention further provides a collet assembly that includes a body and at least two extendable members (275), whereby as the members extend outward, the members are rotated.

Abstract: Apparatus and methods for selectively releasing a first wellbore component (30) to a second wellbore component (40) using a disconnect device. In one embodiment, the method includes coupling a disconnect device (20) to a workstring (40) and a downhole tool (30); performing a downhole operation using the downhole tool, and selectively releasing an upper portion of the disconnect device from a lower portion of the disconnect device, thereby releasing the downhole tool from the workstring. The method may also include reconnecting the upper portion of the disconnect device to the lower portion of the disconnect device. In one embodiment, the disconnect device is capable of transferring torque to the wellbore component.
