Title: Christopher Fletcher and Sensorless Gas Control for Electric Submersible Pumps
Introduction
Christopher Fletcher is an inventor based in Moore, Oklahoma. His work includes a patented approach to monitoring and managing gas production in wells using electric submersible pumps.
Latest Patents
Fletcher is associated with 1 patent: “Sensorless Gas Control for Electric Submersible Pump.” The invention uses a controller to monitor the pump motor’s electrical current and analyze its signature to calculate a Gas Production Index (GPI), which estimates the relative amount of gas being produced. The controller uses the current GPI as a synthetic process variable in a closed-loop control system, adjusting motor speed to pursue a target gas-production level estimated through a future GPI value.
Career Highlights
The patent describes a sensorless method for estimating gas production from motor-current data and using that estimate to guide pump operation. This approach is intended for downhole electric submersible pumps, including those used in liquid hydrocarbon production.
Collaborations
Fletcher’s coworker is Brian Haapanen. The information provided does not specify further details about their collaboration.
Conclusion
Christopher Fletcher’s patented system applies motor-current analysis and responsive speed control to help manage gas production in electric submersible pump operations.
