This MWD system provides highly accurate azimuth and inclination data for all applications from straight-hole through horizontal drilling. The DDS includes a tri-axial fluxgate magnetometer and three quartz accelerometers in APS’s unique ruggedized package. Simultaneous 16-bit analog-to-digital conversion of all channels assures the best possible directional measurement while rotating.
APS Technology offers local NIST-traceable DDS recalibration in China, Russia, Dubai,
and the United States, which simplifies R&M logistics and improves asset utilization.
