Dr-Eem: em MWD System

The DR-Eem MWD system provides continuous inclination, pressure while drilling, shock and vibration data, stick-slip indicators, and zero delay surveys. It has a 3-axis sensor package that captures downhole drilling conditions in real-time to optimize drilling efficiency. The system is suitable for overbalanced and underbalanced drilling environments with rotation up to 200 RPM and can withstand 1000g shocks and vibrations up to 500 Hz.

DR-Eem has a three-axis shock and RPM sensor package that captures and
transmits information regarding the downhole drilling conditions of the tools in real
time. This information can be used to adjust the drilling parameters to optimize
drilling efficiency, increase drilling performance, and minimize damages to the
equipment. This is particularly valuable for ongoing drilling projects where
changes to BHAs and bits can be evaluated to further increase drilling
performance over time.
