51919370, Mar 9, 1993

Filed:

Feb 22, 1991

Appl. No.:

7/659781

Inventors:

Fred R. Cook - Pearl River LA

Assignee:

Texaco Inc. - White Plains NY

International Classification:

E21B 3404

US Classification:

166363

Abstract:

In a subterranean well for producing a production fluid flow through a flow line having a main control valve, a flow control system including means to remotely actuate the main flow valve to open position in response to a radio signal subsequent to the main valve being closed under elective or emergency conditions. Initial fluid flow from the well is commenced by provisionally opening the main flow regulating valve for a predetermined time interval. During said timed interval, if the pressure in the well flow line is not stabilized to an acceptable operating range, the main flow valve will be automatically closed in response to a pressure sensing means which communicates said main flow line with the main valve actuator.

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.
