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 setting tool includes a barrel piston that is configured to couple to a setting sleeve and defines a working surface and a vent port. An upper mandrel is disposed within the barrel piston and defines a power charge chamber that is configured to receive a power charge and includes an upper threaded portion, a lower internal thread, and a plurality of axial discharge ports disposed circumferentially around the lower internal thread. The plurality of axial discharge ports are in fluid communication at one end with the power charge chamber and at the other end with the working surface of the barrel piston. A lower mandrel has an upper end and a lower end, with the upper end in threaded engagement with the lower internal thread of the upper mandrel, and the lower end configured to couple to a frac plug. The power charge chamber includes an upper chamber and a lower chamber, with the lower chamber shaped to open to be in fluid communication with each of the plurality of axial discharge ports.
