Baker Hughes and Aramco debut new ESP technology

TransCoil system designed to help operators bring wells on production faster and more cheaply

Saudi Aramco and Baker Hughes have completed the first installation of a rigless-deployed electrical submersible pumping (ESP) system called TransCoil, which is designed to help operators bring wells on production faster and more cheaply.

The technology, recently installed and commissioned in Saudi Aramco's Khurais field, allows operators to minimise deferred production and lower their overall lifting costs to extend the economic life of their assets, the companies said in a joint statement.

The TransCoil system 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, which improves overall system reliability.

Unlike wireline-deployed ESPs, the fully retrievable TransCoil system does not have an in-well "wet connection", which requires a rig to pull and replace if the wet connection fails.

The TransCoil system cable design also extends the operating range to 12,000 feet compared to traditional coiled tubing-deployed ESP systems, which are limited to around 7000 feet.

The technology can also be installed through a deviation in the wellbore, allowing operators to land the ESP closer to the producing zone for greater reservoir pressure draw down and reserve recovery, Baker Hughes said.
