  • Method and system for predicting failures of sucker rod pumps using scaled load ratios
    Patent number: 11898552
    Abstract: A system and method for predicting failures of rod pumps using a scaled load ratio is configured to: optimize the size of a rolling window, the upper and lower bounds of the normal range of the scaled load ratio, an alert period, and an alert frequency ratio; receive data of a current maximum/minimum loads on a surface rod, and a current speed; remove outliers showing an abnormality; scale the current maximum/minimum loads on the surface rod using the maximum/minimum loads on the surface rod in normal operation; calculate a scaled load ratio; calculate the average of scaled load ratios in the rolling window; determine whether the average of scaled load ratios is in the normal range, and classify the values as normal and abnormal events; calculate the ratio of the abnormal events in the alert period, and generate an alert when the calculated ratio exceeds the alert frequency ratio; and monitor a pump state using the pump failure prediction system.
