A method of conveying an expandable liner hanger (18) in a well includes: conveying the hanger (18) into the well on a work string (22) with a setting tool (20) releasably secured to the hanger by an anchoring device (28); applying left-hand rotation to the work string (22); then lowering the work string, thereby releasing the anchoring device (28) and permitting the setting tool (20) to be retrieved from within the hanger. A method of setting a liner hanger (18) includes: forcing an expansion cone (66) through a hanger portion, thereby expanding the portion; and forcing another expansion cone (72) into another hanger portion, thereby expanding that portion. A method of setting an expandable liner hanger includes: lowering a liner (16) into the well; then connecting the hanger (18) and a setting tool lower section to the liner; then lowering the hanger (18) and the lower section into the well; and then connecting a setting tool upper section to the lower section.
