Abstract: A downhole tool suitable for use in a wellbore, the tool having a mandrel with an inner flowbore extending therethrough from a proximate end to a distal end. There is a ball seat in the inner flowbore, and a groove disposed in the inner flowbore in association with the ball seat. A compressible member is disposed in the groove.

Abstract: A completion assembly suitable for use in a wellbore, the completion assembly having a first sub engaged with a second sub in an assembled or run-in configuration. In the assembled or run-in configuration, the completion assembly is configured to maintain pressure integrity of a primary pressure chamber disposed at least partially within at least one of: the first sub, the second sub, or both.

Abstract: A completion assembly suitable for use in a wellbore, the completion assembly having a power charge mandrel engaged with a downhole tool in a run-in configuration. A power charge or other pyro-technique is disposed in the power charge mandrel in a run-in configuration. Fluid pressure created or increased in the power charge mandrel is conveyed to the downhole tool in a manner that results in movement of the completion assembly to a disconnected configuration. In the disconnected configuration the power charge mandrel is disengaged from the downhole tool, and the power charge mandrel is retrievable out of the wellbore.

Abstract: A downhole tool suitable for use in a wellbore, the tool having a cone or mandrel, a first sleeve, a first ring and a lower sleeve. The downhole tool includes the first sleeve and the first ring, or respective portions thereof, disposed around one end of the cone. After initial activation, the downhole tool is in a first set configuration whereby the lower sleeve is engaged with the expansion sleeve and the cone, leaving a remnant cone-sleeve component configured to move toward or engage a profile.
