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.
Claims20
A method of using a combination downhole assembly in a wellbore, the method comprising:
- running a workstring into the wellbore to a desired location, the workstring comprising the combination downhole assembly coupled therewith, the combination downhole assembly further comprising:
- a setting tool assembly, wherein the setting tool assembly further comprises:
- a head adapter coupled with the workstring;
- a power charge mandrel coupled with the head adapter, the power charge mandrel having a power charge disposed therein;
- a barrel piston releasably coupled with the power charge mandrel;
- a tension mandrel disposed, at least partially, within the barrel piston, and wherein a pressure chamber is accessible between the power charge mandrel and the tension mandrel;
- a downhole tool coupled with the setting tool assembly;
- a setting sleeve having a first setting sleeve end coupled with the barrel piston via one or more securing members, and a second setting sleeve end coupled with the downhole tool;
- causing an activation signal to transmit in a manner to activate the setting tool assembly, whereby the power charge burns to create an increase in fluid pressure within the pressure chamber sufficient to move the barrel piston,
- wherein the barrel piston comprises a barrel piston end having an inner diameter, wherein the tension mandrel comprises a tension mandrel end having an outer diameter, and wherein the outer diameter is larger than the inner diameter.
A method of using a combination downhole assembly in a wellbore formed at a worksite, the method comprising:
- running a workstring into the wellbore to a desired location, the workstring comprising the combination downhole assembly coupled therewith, the combination downhole assembly further comprising:
- a setting tool assembly, wherein the setting tool assembly further comprises:
- a head adapter coupled with the workstring;
- a power charge mandrel coupled with the head adapter, the power charge mandrel having a power charge disposed therein;
- a barrel piston releasably coupled with the power charge mandrel;
- a tension mandrel disposed, at least partially, within the barrel piston, and wherein a pressure chamber is accessible between the power charge mandrel and the tension mandrel;
- a downhole tool coupled with the setting tool assembly;
- a setting sleeve having a first setting sleeve end coupled with the barrel piston via one or more securing members, and a second setting sleeve end coupled with the downhole tool;
- causing an activation signal to transmit in a manner to activate the setting tool assembly, whereby the power charge burns to create an increase in fluid pressure within the pressure chamber sufficient to move the barrel piston;
- pre-assembling the setting tool assembly with the downhole tool to form the combination assembly, the pre-assembly occurring at a location at least 10 miles away from the worksite;
- and
- delivering the pre-assembled combination unit to the worksite.
A combination downhole assembly for use in a wellbore, the combination assembly comprising:
- a setting tool assembly, wherein the setting tool assembly further comprises:
- a head adapter coupled with the workstring;
- a power charge mandrel coupled with the head adapter, the power charge mandrel having a power charge disposed therein;
- a barrel piston releasably coupled with the power charge mandrel, the barrel piston comprising a working surface;
- a tension mandrel disposed, at least partially, within the barrel piston;
- a downhole tool coupled with the setting tool assembly;
- a setting sleeve having a first setting sleeve end coupled with the barrel piston via one or more securing members, and a second setting sleeve end coupled with the downhole tool.
The combination assembly of 14, wherein the working surface has a surface area in a surface area range of about 4 square inches to about 8 square inches, and wherein the securing members comprise dry pins.
