Abstract

Methods and systems are provided for detecting and mitigating stall of a downhole motor driven by flow of drilling fluid through the downhole motor, which employ a BHA that includes at least one first downhole sensor and at least one second downhole sensor operably disposed above the downhole motor. The methods and systems generate time-series first data representing measurements of the rotational speed of a collar disposed at the uphole end of the downhole motor or part of the BHA disposed above the downhole motor made by the at least one first downhole sensor over time as well as time-series second data representing measurements of the vibration of the BHA made by the at least one second downhole sensor over time. Stall of the downhole motor can be automatically detected by analysis of the time-series first data and the time-series second data. Upon detecting stall of the downhole motor, at least one action can be initiated to mitigate the stall of the downhole motor.
