ABSTRACT:
A method is disclosed which, in one aspect, includes providing power to a system for controlling a wellhead from a self-contained stand-alone power source, controlling the delivery of power to the system with a control unit (in one aspect a microprocessor control unit), using various valves to control flow of fluids from within the well and from the well in one or more flowlines, and monitoring various parameters both in the flowlines and in and around the well and the wellhead, including but not limited to fluid pressures and emergency conditions, and shutting-in the well in response to certain signals generated by the system based on the monitoring.
