“ZEiTECS has deployed the world’s first successful commercial electrical submersible pump (ESP) shuttle system. The technology enables conventional ESP systems (pump, motor, and seal) to be run, retrieved, and redeployed safely on wireline without a rig. Since wireline units can be mobilized in a matter of hours, unforeseen pump failures no longer have to result in days, weeks, or months of deferred or lost production, leading to significant cost savings.
The ESP Shuttle installation program in Petroleum Development Oman using Wood Group ESP pump systems demonstrated multiple electromechanical connections and reconnections of the ESP on wireline. After successful system startup, the complete ESP system was retrieved and redeployed via wireline after a month of operation. Production recommenced with well performance matching the historic performance of a tubing-conveyed ESP.”
