Abstract
A drilling system can include a mud motor arranged in a drill string and a turbine shaft operatively coupled to a drill bit. The drilling system can also include a plurality of turbine stages axially arranged along a portion of the turbine shaft, a measure-while-drilling (MWD) tool operatively and communicably coupled to the mud motor, and a pressure sensor configured to detect pressure pulses generated by the mud motor and generate data signals corresponding to the pressure pulses. Further, the drilling system can include an electronics module communicably coupled to the pressure sensor and configured to process the data signals and thereby calculate a rotational speed of the mud motor. Furthermore, the drilling system can include a communications module communicably coupled to the electronics module and configured to transmit signals indicative of the rotational speed of the mud motor to a surface location.
