ABSTRACT:
System for remotely controlling the start-up of a closed-in well. A radio signal transmitted to the well actuates a main flow control valve to provisionally commence flow from the well into a conduit. During the provisional period, a comparator electronically analyzes the well's immediate operating pressure against a preferred operating parameter, and generates a signal representing the difference between the two. A generated signal further initiates such commands as will sustain well flow if the latter is within the preferred operating parameters, or after the brief provisional operating period, discontinues flow if necessary.
