Scientific Drilling International (SDI) is a leading global provider of highly accurate Measurement-While-Drilling (MWD) services. With over twenty years of in-house engineering and manufacturing excellence, our MWD systems have proven reliability and cost-effectiveness worldwide.

Reliability and safety remain the cornerstones for all Scientific Drilling’s MWD services. We employ a proactive environmental condition based maintenance program that is based on the TUF point system (True Utilization Factor). This system quantifies accumulated tool wear based on time at temperature and vibration levels down hole. The integration of crucial drilling factors (e.g., lateral vibration, axial vibration, stick slip and temperature) in combination with our safety culture allows Scientific Drilling’s customers to realize better, safer performance with a decreased risk of NPT.
