DR - Shockwave
Positive Pulse MWD System


The DR-Shockwave is D&R’s leading system for the past twelve years. It uses a motor-driven pulse assembly to provide a reliable measurement of the boreholes position by sending the data through the drilling fluid column via pressure waves. On the surface, our instrumentation decodes this sequence and translates it into inclination, azimuth, tool face, and gamma information.
