Abstract
A system for permitting deployment of a polished bore receptacle, seal stack and production tubing in a single downhole trip into a wellbore. The system includes a polished bore receptacle, production tubing, a seal stack disposed about the production tubing, and a one trip seal latch that couples the production tubing to the polished bore receptacle. The seal latch includes an outer latch housing and an inner latch housing. The outer housing and inner housing are connected by a releasable coupling device. Thus, the polished bore receptacle can be moved downhole for latching to a packer without insertion of the seal stack into the interior of the polished bore receptacle. Upon latching of the polished bore receptacle to the packer, the coupler may be selectively released to permit insertion of the seal stack into the polished bore receptacle.
