摘要： 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.

摘要： 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.

摘要： 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.
