Abstract
A monitoring and control system for a dewatering pump configured to dewater a gas well is provided. A dewatering pump is driven at a first speed to pump fluid out of a well annulus. A fluid level detection device is configured to identify a change of fluid level in the well annulus occurring between a first time and a second, later time. A controller is configured to change the speed of the dewatering pump from the first speed to a second speed based upon the identified change in fluid level. Several embodiments of the fluid level detection devices are provided.
