Methods and apparatus for pairing rod pump controller position and load values

A rod pump controller for use with a pumping unit, the rod pump controller comprising:

• a first processor to:
• monitor, via a sensor communicatively coupled to a rod pump controller of the pumping unit, at least one of a rotational position of a crankarm or a number of revolutions of a motor of the pumping unit;
• determine, via the rod pump controller, a first position value of a polished rod of the pumping unit;
• assign a first time value to the first position value;
• receive first load values of the polished rod from a first load sensor via a wireless communication apparatus to be communicatively coupled to the rod pump controller;
• assign second time values to respective ones of the first load values;
• adjust each of the second time values to respective third time values based on a wireless communication delay value;
• determine a second load value associated with the first position value at the first time value based on the first load values and the third time values;
• correlate the second load value with the first position value to enable the rod pump controller to provide a pump dynamometer card;
• and
• operate the pumping unit based on the pump dynamometer card obtained using the second load value and the first position value.

A non-transitory machine readable medium comprising instructions that, when executed, cause a machine to:

• monitor, via a sensor communicatively coupled to a rod pump controller of a pumping unit, at least one of a rotational position of a crankarm or a number of revolutions of a motor of the pumping unit;
• determine, via the rod pump controller, a first position value of a polished rod of the pumping unit;
• assign a first time value to the first position value;
• receive first load values of the polished rod from a first load sensor via a wireless communication apparatus communicatively coupled to the rod pump controller;
• assign second time values to respective ones of the first load values;
• adjust each of the second time values to third time values based on a wireless communication delay value;
• determine a second load values associated with the first position value at the first time value based on the first load values and the third time values;
• correlate the second load value with the first position value to enable the rod pump controller to provide a pump dynamometer card;
• and
• operate the pumping unit based on the pump dynamometer card obtained using the second load value and the first position value.
