A technique facilitates removal of gas from a gas-sensitive region in an electric submersible pumping system. A gas purging system is integrated into the electric submersible pumping system. During operation of the electric submersible pumping system, the gas purging system also is operated to move gas away from the gas-sensitive region, e.g. a thrust bearing region, and to a collection region or other suitable region. In some embodiments, the gas which accumulates in a collection region may be discharged to a region external of the electric submersible pumping system.

Gas purging for electric submersible pumping system

A system can include an interface to receive sensed data and economic data; a production control framework that includes a module for modeling motor efficiency of an electric submersible pump, a module for modeling gas composition of a fluid being pumped by an electric submersible pump, a module for modeling solid dynamics in a fluid being pumped by an electric submersible pump, a module to update one or more of the modules for modeling in response to receipt of data via the interface; and an interface to output control commands to a controller for an electric submersible pump based at least in part on data received by the interface and analyzed by the production control framework. Various other apparatuses, systems, methods, etc., are also disclosed.
