Title: Granval W Westerman: Innovator in Petroleum Recovery Technologies
Introduction
Granval W Westerman is a notable inventor based in Midland, TX (US), recognized for his contributions to petroleum recovery technologies. With a total of 2 patents, Westerman has developed innovative solutions that enhance the efficiency and safety of oil extraction processes.
Latest Patents
Westerman's latest patents include a technique for the control of injection wells and a well pump-off controller. The injection well control method and apparatus he developed monitors bottomhole pressure adjacent to an underground formation receiving injected fluids. This system adjusts fluid injection rates to minimize unwanted variations in bottomhole pressure during secondary or tertiary petroleum recovery operations. Notably, the injection controller operates on a solar-powered circuit, eliminating the need for electrical power lines in remote locations. The well pump-off controller is designed to measure current or load to shut down a motor of a walking beam type pumping unit in the event of pump-off. This system utilizes a peak picker to identify either minimum current or maximum load, coupled with an integrator that tracks current or load during each stroke cycle. A threshold device generates a control signal to shut down the motor if the integrator output does not reach a predetermined threshold.
