Pitfalls in Performance-Data Tracking of Sucker-Rod Pumped Wells

摘要

Mean time between failure (MTBF) has been the standard fortracking field performance of sucker rod pumped wells but itcan lead to improper conclusions and applications. A newmethod using cycle time and loading can greatly improve theunderstanding of the true performance of sucker rod pumpedsystems. Using proper data tracking of system performanceand wear based on cycles and magnitude can greatly increasethe understanding of a well system and be a proper guide tooptimization.
