Abstract: A downhole tool suitable for use in a wellbore, the tool having a cone, a first sleeve, and a lower sleeve. The downhole tool includes the first sleeve, or a portion thereof, disposed around one end of the cone. After activation, the lower sleeve is engaged with the first sleeve, leaving a remnant cone-sleeve component configured to plug a restriction.

Abstract: A combination downhole assembly having a setting tool assembly coupled with a downhole tool. The setting tool assembly has an adapter housing configured to couple with a part of a workstring, and a power charge mandrel coupled with the adapter housing. There is a barrel piston releasably coupled with the power charge mandrel. During run-in, the barrel piston is in a first position. Upon activation of a setting sequence, the barrel piston moves to a second position. The setting sequence results in the barrel piston engaging a tension mandrel configured with a deceleration feature.

Abstract: A downhole tool having a mandrel and a slip. The mandrel has a mandrel body having a proximate end; a distal end; and an outer surface. The slip is a hybrid slip having a slip shell engaged with a slip core. When the slip shell is engaged with the slip core, at least one break point of the slip shell is aligned with a respective break point of the slip core.

Abstract: A setting tool assembly configured to couple with a part of a workstring, the assembly having an inner housing coupled with one or more other components. A trigger device is coupled with a movable piston. During run-in, the piston is in a first position. Upon activation, the trigger device undergoes an altering event whereby the piston moves to a second position as a result of a pressure acting thereon.

Abstract: A downhole tool having a mandrel, and a bottom slip disposed around the mandrel. The bottom slip includes a circular body having a one-piece configuration characterized by a plurality of slip segments by at least partial material connectivity therearound. The bottom slip is made of a filament wound composite material, which means the bottom slip has a plurality of layers joined by respective interface layers. An outer slip surface of at least one of the plurality of slip segments is defined in cross-section by a plane P that intersects a longitudinal axis of the downhole tool at an angle a1 when the bottom slip is in an unset position.
