Measurement While Drilling
Measurement While Drilling, MWD, is an optional function for logging and recording drill performance parameters during drilling of holes in a tunnel.

One of the most difficult, yet extremely important, steps in drifting and tunnelling is to predict the geological and geomechanical properties ahead of the tunnel face, particularly in stretches where rock formations are expected to vary considerably. Early prediction of these properties can save much valuable time and money and improve safety by allowing appropriate measures to be taken before reaching the difficult and dangerous formations.
Measurement While Drilling, MWD, is a method for collecting appropriate drilling data and presenting it systematically on the office computer for evaluation and prediction.
The MWD method has been developed to be an integral part of the normal drill and blast activities. A Boomer rig with Rig Control System (RCS) can be upgraded for MWD application. Since the procedure of collecting MWD data can be combined with other normal drilling activities, this method can be easily integrated into normal tunnelling activities.
MWD data can be used for immediate evaluation. As soon as the recorded data is available, the results of the recorded data can be plotted and evaluated.
Features and benefits
- Eight different parameters can be sampled during drilling
- Data can be sampled during normal drilling at a pre-defined interval
- Data is handled and stored in the rig’s Rig Control System
- Easy transfer of data to and from the drill rig
