MWD
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.

Word of the Week – Stored Heat
Stored Heat Calculated thermal energy stored in a volume of hot rock. It is calculated using the rock volume, porosity, rock density, specific heat of rock, and the difference between the reservoir temperature and the background temperature given by the geothermal...
