A completion tool for gravel pack and frac pack operations for installing a sump packer and perforating a casing in one trip of a work string. The completion tool is disposed on the end of a work string and includes a perforating gun and a packer attached to the distal end of the completion tool by a coupling. The coupling is such that once the packer is set, the rest of the completion tool can be detached from the packer. After detachment, the completion tool can be repositioned to fire the perforating gun. Positioning of the packer and perforating gun may be accomplished by correlating off of other equipment or by use of logging-while-drilling or measurement-while-drilling equipment incorporated into the completion tool. |
