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.
Claims14
A one-trip well completion method, comprising:
- running in a perforating gun and a packer on tubing;
- setting the packer;
- automatically releasing said gun from said packer as a result of setting said packer;
- firing said perforating gun;
- removing said gun from the wellbore;
- using a setting tool to set the packer;
- securing said setting tool to said packer with a tensile element;
- releasing said packer by breaking said tensile element when setting said packer;
- securing support for at least one collet with said tensile element;
- and
- using said collet when supported to secure said setting tool to said packer.
A one-trip well completion method, comprising:
- running in a perforating gun and a packer on tubing into a deviated wellbore;
- setting the packer;
- releasing said gun from said packer;
- firing said gun without use of a wireline signal;
- removing said gun from the wellbore;
- using a setting tool to set the packer;
- securing said setting tool to said packer with a tensile element;
- releasing said packer by breaking said tensile element when setting said packer;
- securing support for at least one collet with said tensile element;
- and
- using said collet when supported to secure said setting tool to said packer.
