Abstract :
Variable-voltage d-c drives have been applied successfully to both the cable tool and rotary methods of oil well drilling. This article gives a comparison of characteristics of 4 different combinations of electrical equipment for this service. Although the method of comparison used is applied only to internal combustion engine d-c electric drives, it may be used advantageously for comparing other types of prime movers.
