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.
