Abstract: A decelerator device (210), or shock absorber, for slowing the speed of a moving ball (106) approaching a ball seat (104) anchored in a tool (102) in a pipe string (200) of a subterranean well (220). The decelerator device (210) has a ball passage (208), an entrance port (204) which directs the moving ball (106) from an open mouth (202) of the entrance port (204) to a drag-inducing throat (207) of the ball passage (208), and directs the moving ball (106) towards a ball seat (104). The body (214) of the decelerator device (210) is made of a deformable, solid-state yielding material that displaces away from a centerline (103) of the ball passage (208) as the moving ball (106) with a diameter (105) larger than the throat (207) passes through the decelerator device (210).

Abstract: The present invention relates to downhole tools and methods of removing such tools from wellbores.

Abstract: A well tool including swellable material and integrated fluid for initiating swelling. A well tool includes a swellable material and a reservoir for containing a fluid of a type which causes the swellable material to swell. A method of swelling a swellable material included in a well tool includes the steps of: positioning the well tool in a well; and then activating a fluid to cause swelling of the swellable material. A method of swelling a swellable material includes the steps of: providing the swellable material which is capable of swelling when contacted by a fluid; positioning the swellable material in an environment in which the swellable material is contacted by another fluid which does not cause the material to swell; and swelling the swellable material by contacting the swellable material with the first fluid while the swellable material remains in contact with the other fluid.

Abstract: A wellbore servicing tool comprising a housing comprising ports, a triggering system, a first sliding sleeve transitional from a first position to a second position, and a second sliding sleeve transitional from a first position to a second position, wherein, when in the first position, the first sliding sleeve retains the second sliding sleeve in the first position, wherein, when in the first position, the second sliding sleeve prevents a route of fluid communication via the one or more ports of the housing and, when is in the second position, the second sliding sleeve allows fluid communication via the ports, and wherein the triggering system is configured to allow the first sliding sleeve to transition from the first position to the second position responsive to recognition of a predetermined signal comprising a predetermined pressure signal, a predetermined temperature signal, a predetermined flow-rate signal, or combinations thereof.

Abstract: A mechanism for use in a wellbore servicing tool includes a continuously rotating ring within a servicing tool, and a limiting mechanism configured to engage the ring and lock the ring upon a predetermined degree of rotation of the ring. The mechanism may comprise a portion of an actuation assembly for use in a wellbore.
