Paper Number: SPE-192177-MS
... results in high current flow, higher voltage drop and heat loss in the system. In PMMs, there is no rotor magnetization needed, and the motor reactive power is greatly reduced, and as a result, PMMs have higher power factors than IMs. Motor efficiency measures how much real power provided to the motor...

... of the wellbore. These problems may include premature bit wear, slow drilling rate (i.e. low ROP) and, in most severe cases, a stuck pipe which in some cases can lead to complete loss of the well. Moreover, measuring the cleaning efficiency using field or experimental measurements is highly costly and time...
