System and method for creating a fluid seal between production tubing and well casing

A single trip system for completing a well that traverses a subterranean formation, the system comprising:

• a releasable production packer positioned within a well casing, the releasable production packer including at least one seal element positioned around a section of a production tubing;
• an expander member positioned within the production tubing that travels longitudinally through the releasable production packer to expand the section of the production tubing downhole, thereby creating the seal between the production tubing and the well casing;
• and
• a cross-over assembly operably associated with the expander member through which a treatment fluid is delivered into an annulus between the production tubing and the well casing downhole of the releasable production packer.
