ZEiTECS' Deployment of ESP Shuttle System Lifts Expectations
Greg Schneider, President & Chief Executive Officer of ZEiTECS has announced the world's first successful commercial deployment of the revolutionary ESP Shuttle system.
The ZEiTECS ESP Shuttle technology enables conventional electric submersible pump (ESP) systems (pump, motor & seal) to be run, retrieved and redeployed safely on wireline without a rig. The success represents a major breakthrough for operators, removing the conventional dependence on workover rigs for ESP deployment. 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 (PDO) using Wood Group ESP pump systems demonstrated multiple electro-mechanical connections and re-connections of the ESP on wireline. After successful system start-up, the complete ESP system was retrieved and redeployed via wireline after a month of operation. Production re-commenced with well performance matching the historic performance of a tubing-conveyed ESP.
The ESP Shuttle system was also demonstrated at the Rocky Mountain Oilfield Testing Center in Wyoming, USA to the representatives of four super-majors. The demonstration included three complete installations, redeployment and operation of the ESP on wireline and 18 electro-mechanical connections and reconnections before the working system was retrieved for inspection -- all without incident.
