Refers to Measurement While Drilling which for directional drilling includes geospatial information that is used to steer the bottom hole assembly (BHA). Inclination and azimuth are surveyed using accelerometers and magnetometers which are incorporated into MWD tools. Other MWD information includes rotational speed of the drill string, type and severity of downhole vibration, temperature, and torque and weight on bit.
