Pumpdown (TFL) technology for subsea completions
This study describes the latest innovations in pump-down equipment and methods that provide economical, reliable solutions to offshore production well maintenance in deep or shallow subsea completions worldwide. Demands for full-bore tubing have led to tool designs that negotiate wellhead entry loops, thus making single and multizone completions, gas lift, and surface-controlled subsurace safety systems feasible. Large-bore TFL equipment can be used for subsea completions. Typical completions include single- or multizones with gas-lift capabilities and surface-controlled, down-hole safety systems. Operational problems caused by fluid losses, down-hole tool location, plugging at the wellhead, and down-hole tool selectivity have been minimized because of these new developments. The economics of servicing subsea wells with pump-down tools become evident when comparing the costs of vertical re-entry of a well. Using these tools gives the oil industry more economical and reliable means for completing, producing, and maintaining subsea wells.
