DR - EEM
EM MWD system

DR-EEM is D&R’s leading MWD tool that provides information consistently with every connection for all over-balanced and under-balanced environments — full MWD, precision inclination/azimuth, gamma-ray logging and bore/annular pressure while drilling (PWD).

3 AXIS SHOCK & RPM SENSOR PACKAGE

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.
