Term · Oil and gas · MLC-T-OAG-004307

A graphical plot of load versus displacement for a sucker rod pumping unit, recorded by a dynamometer. This card illustrates the forces acting on the polished rod throughout a pumping cycle, providing diagnostic information about the downhole pump and rod string. Analysis of the card reveals conditions such as fluid pound, gas interference, or worn pump components.
