Abstract

A fully programmable system for controlling the operation of one or more gas or oil production wells by controlling the intermittent operation of the wells in response to either programmed information or monitored and measured criteria related to the wells themselves. The system includes battery powered solid state circuitry comprising a keyboard, a programmable memory, a microprocessor, control circuitry, means for inputting measured parameters from a plurality of transducers and a liquid crystal display system for displaying information contained within the memory, or one of the measured parameters. In one embodiment, the system monitors pressure, flow, and other parameters of a plurality of wells drawing petroleum products from a common reservoir to control the intermittent operation of either gas injection to the well, outflow of fluids from the well, or shutting in of the well to maximize the overall output of the entire array of wells drawing from the common reservoir.
