ABSTRACT:
New apparatus and methods are disclosed for controlling the operation of a rod-pumped oil well. The load on and position of the rod string are measured, an integration calculation related to the work done during a portion of the downstroke is performed, and the result is compared to a reference value, to detect a pumped-off condition in the well.
