Abstract
Abstract A method and system for pumping-well control including determination of a production profile for the well. The profile consists of a function that defines the normal producing conditions when the well fluid is pumped out of the well at a greater rate than it is produced therein. Optimum producing conditions may then be determined and set. In addition, the magnitude of the load on the pump motor is monitored and fed out for remote indication and/or control.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
90 words
In a system for controlling a pumping well, said system including a beam-type reciprocating pump driven by a motor, said pump having cycles including an up stroke and a down stroke successively, the improvement comprising means associated with said well for providing a cyclic waveform signal proportional to the load on the motor driving said pump, means for recording said waveform signal continuously over a period of a plurality of said pump cycles, and computer means for receiving said waveform signal and for providing an output to control said motor.
Claim 2
Dependent Claim
90 words
In a system for controlling a pumping well, said system including a beam-type reciprocating pump driven by a motor, said pump having cycles including an up stroke and a down stroke successively, the improvement comprising means associated with said well for providing a cyclic waveform signal proportional to the load on the motor driving said pump, means for recording said waveform signal continuously over a period of a plurality of said pump cycles, and computer means for receiving said waveform signal and for providing an output to control said motor.
Claim 3
Dependent Claim
37 words
In a system according to claim 7, the improvement also comprising means for recording in real time a plurality of consecutive cycles of said waveform signal, and high-speed means for reproducing said recorded signals in compressed time.
Claim 4
Dependent Claim
12 words
A system according to claim 2 having a plurality of pumping wells.
Claim 5
Dependent Claim
33 words
A system according to claim 3 further including means for switching from one well to the next in said compressed time so that said computer means may supervise all of said wells continuously.
