Saudi Aramco recently installed and tested the functionality of its Baker Hughes’ TransCoil rigless deployed electrical submersible pumping (ESP) system, which is expected to cut down on installation and replacement costs for ESPs and bring wells online faster, Gulf News reported.
By eliminating the need for an expensive rig to replace the ESP, it is particularly advantageous in offshore wells where not only rig intervention costs are expensive, but also where limited rig availability can delay ESP replacement, Trade Arabia informed.
TransCoil system also features an inverted ESP system with the motor connected directly to the powered CT. By eliminating the traditional ESP power cable-to-motor connection, the technology further improves overall system reliability.
The combination of the power cable and the CT into a cohesive deployment string extends the operating range of the TransCoil system to 12,000ft and enhances reliability, compared to existing CT deployed ESPs that simply pull the power cable through the CT.
The TransCoil nickel alloy outer jacket also provides corrosion protection in harsh environments.
Home to more than 1,500 ESP installations with more than 100 change outs per year in a harsh production environment, Saudi Aramco is constantly developing ESP technologies to reduce change-out time and improve run life.
