In response to this challenge, the 550 series ZEiTECS Shuttle system was installed in the well with a standard 450 / 400 series ESP. The ESP ran for 72 days when it experienced an unexpected failure. After the initial response, the ZEiTECS Shuttle system was used to riglessly replace the ESP on coiled tubing in 1 day, 21 hours, and 15 minutes.

After experiencing multiple ESP failures, a customer needed to reduce well downtime when replacing the ESP. In Ecuador, it is typical for rigs and hoists to take 7 to 10 days to respond to an ESP failure and then an additional 4 days to replace an ESP on jointed tubing. For this well, the inability to quickly source a rig or rapidly retrieve ESPs would result in deferred production of up to 9,000 bbl for each heavy workover required.
