An upper-completion single trip system is described which includes a hydraulic internal seal receptacle assemble. The HISR assembly includes an overshot assembly selectively connected to a mandrel assembly. Once fully actuated, relative axial motion therebetween is allowed, which provides a spacer apparatus for the tubing above and below the HISR assembly. A shearable anchor latch as well as an indexing mule shoe are also provided in the HISR system, which allow multiple completion steps to be performed in a single trip. The HISR system is particularly well-suited for installation of permanent downhole gauges or intelligent systems--installations where rotation of pipe is prohibited. The system is also particularly well-suited for submersible pumps. A method of performing multiple completion activities in a single trip is also described.
