CFST is economical from a lifecycle cost perspective. It outlasts any high alloy metallic tubing. Considering the cost of several workovers, new tubing, chemical treatment, and cashflow impact resulting from shut-in periods, the price is very competitive. CFST is more economical than 13Cr tubing and certainly a lot less expensive than Duplex or Inconel tubing. CFST is priced slightly above CR13 tubing but will last many times longer.
