Graph:  Shuttle Rigless ESP Decreases ESP Replacement Time by 87%
In response to this challenge, the 550 series Shuttle™ rigless ESP was installed in the well. The ESP ran for 72 days and then it experienced an unexpected failure. It was replaced using coiled tubing in just 1 day, 21 hours, and 15 minutes.

Background

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