Abstract
A method and apparatus for controlling a speed of a pump operating in a well. A first step involves monitoring a production flow rate of fluids produced from the well. A second step involves controlling the speed of the pump with reference to the production flow rate by increasing the speed of the pump when the production flow rate is rising and decreasing the speed of the pump when the production flow rate is declining.
Claims3
An apparatus for controlling a speed of a pump operating in a well, comprising:
- a controller;
- a sensor in communication with the controller, the sensor monitoring a production flow rate of a continuous flow of fluids produced from the well based upon a series of level readings at regular intervals over time indicating a rate of rise in a production tank and providing production flow rate data to the controller;
- and
- a pump speed control device in communication with the pump and in communication with the controller, the controller sending signals to the pump speed control device to increase the speed of the pump by user configurable increments when the production flow rate data from the sensor indicates that the production flow rate is rising and decrease the speed of the pump by user configurable increments when the production flow rate data from the sensor indicates that the production flow rate is declining.
