Coiled tubing applications: Coiled tubing used to fish coiled tubing from a live gas/condensate well

This case study examines the techniques required to recover a coiled-tubing (CT) fish from a live gas/condensate well by use of CT. These procedures recently were implemented offshore Vietnam, where an extremely fluid-sensitive formation prevented killing the well because the formation likely would not have recovered. Using the techniques described in the full-length paper, a 1.50-in., 9,177-ft-long CT fish was recovered from a well while keeping the well on production.
