Abstract

An expansion-set fluid production assembly transfers well fluids from a casing string 12 to a production tubing string 112. A tubular anchor 72 and tubular expander 70 may be positioned downhole on a running tool at a desired depth along the casing string 12. An actuator assembly 10 may forcibly move the tubular expander 70 into the tubular anchor 72, expanding the tubular anchor 72 to seal and secure the tubular anchor 72 against the casing string 12. The running tool actuator assembly 10 may be removed, leaving the expanded tubular anchor 72 and tubular expander 70 downhole. A seal nipple 122 may be sealed with the tubular expander 70 and to the production tubing string 112. Fluids may then be recovered from the wellbore through the casing string 12, through the fluid production assembly, and into the production tubing string 112.
