Abstract
Abstract A one-trip system for placement and setting a downhole packer or plug is disclosed. The packer is settable in a variety of ways, including hydraulically, acoustically by pressure pulse signals, or some combination. Use of hydraulic pressure triggers a pressure-creating reaction to initiate the setting of the packer. The setting mechanism for the packer breaks clear of the packer upon setting and allows the tubing-conveyed perforating gun, which is already preassembled as part of the string, to be accurately positioned and fired.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
67 words
A one-trip well completion method, comprising: running in a packer, a setting tool, and a perforating gun into the wellbore together on tubing; pressurizing an annular space around said tubing to actuate said setting tool; setting the packer with said setting tool; releasing the setting tool from the packer; positioning the perforating gun; setting off the gun with applied pressure in said tubing; and removing the gun.
Claim 2
Dependent Claim
67 words
A one-trip well completion method, comprising: running in a packer, a setting tool, and a perforating gun into the wellbore together on tubing; pressurizing an annular space around said tubing to actuate said setting tool; setting the packer with said setting tool; releasing the setting tool from the packer; positioning the perforating gun; setting off the gun with applied pressure in said tubing; and removing the gun.
Claim 3
Dependent Claim
19 words
The method of claim 1, further comprising: using a tensile element to secure the setting tool to the packer.
Claim 4
Dependent Claim
81 words
A one-trip well completion method, comprising: running in a packer and perforating gun into the wellbore together; setting the packer with a hydraulically actuated setting tool; using a tensile element to secure the setting tool to said packer; securing support for at least one collet with said tensile element; using said collet when supported to secure said setting tool to said packer; releasing the setting tool from the packer; positioning the perforating gun; setting off the gun; and removing the gun.
Claim 5
Dependent Claim
81 words
A one-trip well completion method, comprising: running in a packer and perforating gun into the wellbore together; setting the packer with a hydraulically actuated setting tool; using a tensile element to secure the setting tool to said packer; securing support for at least one collet with said tensile element; using said collet when supported to secure said setting tool to said packer; releasing the setting tool from the packer; positioning the perforating gun; setting off the gun; and removing the gun.
Claim 6
Dependent Claim
30 words
The method of claim 3, further comprising: breaking said tensile element while setting said packer; undermining support of said collet by said breaking; releasing from said packer by said undermining.
Claim 7
Dependent Claim
29 words
The method of claim 3, further comprising: initiating pressure building in said setting tool; creating differential movement due to said pressure building; setting the packer with said differential movement.
Claim 8
Dependent Claim
30 words
The method of claim 5, further comprising: using said differential movement to break a tensile member on said setting tool; releasing said setting tool from said packer by said breaking.
Claim 9
Dependent Claim
24 words
The method of claim 5, further comprising: using hydraulic pressure to initiate said pressure building; moving at least one piston by said pressure building.
Claim 10
Dependent Claim
28 words
