ABSTRACT:
A travel joint and latching assembly is connected below a gravel pack service tool to set an isolation assembly while performing backwashing and gravel pack operations, in a single trip. The travel joint is protected against inadvertent expansion by a positive mechanical lock assembly which isolates and decouples mechanical loading forces which may arise during the setting of the packer and during gravel pack operations. Inadvertent set of the hydraulic packer during backwashing operations is prevented by a hydraulic setting tool which includes a shear sleeve and an expandable C-ring drop ball seat.
