Hart’s E&P: Tech Trends

First rigless-deployed ESP system installed Baker Hughes recently installed the first TransCoil rigless-deployed electric submersible pumping (ESP) system, which is designed to help operators bring wells on production faster and lower the costs associated with installing and replacing ESPs, the company said. Because they can eliminate the need for a rig in fields where rig availability is a concern or where high intervention costs can limit artificial lift options, operators can minimize deferred production and lower their overall lifting costs to extend the economic life of their assets. The TransCoil system developed in participation with Saudi Aramco features an inverted ESP system with the motor connected directly to a new proprietary power cable configuration, eliminating the traditional ESP power cable-to-motor connection.
