ABSTRACT:
A well completion system for creating a seal between a production tubing (30) and a well casing (34) positioned within a wellbore (32) comprises a production packer (46) that includes a section of the production tubing (30) and at least one seal element (60). The production tubing (30) is then positioned within the well casing (34) that lines the wellbore (32). An expander member (56) that is positioned within the production tubing (30) then travels longitudinally through the production packer (46) to expand the section of the production tubing (30) downhole that includes the seal element (60). This expansion creates a sealing and gripping relationship between the production tubing (30) and the well casing (34).
