MWD rotary pulser – mud pulse transmitter
Sigdrill’s mud pulse family of directional and directional plus gamma systems provides reliable and flexible Measurement While Drilling (MWD) performance in combination with our second-generation Rotary Pulser – the toughest top-mounted pulser in the industry. This MWD system provides highly accurate azimuth and inclination data for all applications, from straight-hole through horizontal drilling. Rapid and accurate toolface transmission enables the most complex well paths to be drilled with confidence.
Sigdrill also offers an EM Telemetry-based MWD system, which uses the same flow subs and is a drop-in alternative for the mud pulse transmitter.
The mud pulse MWD system’s downhole portion includes a rugged directional sensor package with NIST-traceable magnetometer calibration; a reliable, field-proven Rotary Pulser; and battery and/or turbine alternator† for power. Sigdrill’s modular design allows for the addition of other functions such as high-quality gamma and/or vibration logging.
