System and method to monitor and control reciprocating rod lift system

A computerized device for use with a reciprocating rod lift system, the reciprocating rod lift system having a surface pumping unit with an electric motor and having a downhole pump, the computerized device comprising:

• memory storing pump card information, energy draw measurements, and first and second energy draw thresholds, the pump card information being obtained in real time during operation of the reciprocating rod lift system, the pump card information relating position and load of the reciprocating rod lift system, the energy draw measurements of the electric motor being obtained in real time during the operation of the reciprocating rod lift system;
• and
• one or more processors in communication with the memory and being configured to:
• associate the energy draw measurements into a scale of the pump card information;
• associate a first energy draw threshold and a second energy draw threshold into the scale of the pump card information, the first energy draw threshold associated with the electric motor being operated in a downstroke of the reciprocating rod lift system, the second energy draw threshold associated with the electric motor being operated in an upstroke of the reciprocating rod lift system;
• and
• initiate at least one first operational event in response to at least one of:
• a first determination that the energy draw measurements in the downstroke exceeds the first energy draw threshold;
• a second determination that the energy draw measurements in the upstroke exceeds the second energy draw threshold;
• and
• a third determination that a difference between the energy draw measurements in the downstroke and the energy draw measurements in the upstroke exceeds a third threshold.
