Mud Pulse

The positive pulse measurement while drilling system (PP-MWD) principle is based on the temporary restriction of drillstring mud flow to create a series of pressure spikes that form a communicative pulse waveform that is decoded using surface equipment. Downhole configurations are fully modular adding the flexibility of adjustments specific to BHA. Reliable surface decoding is further enhanced with the added option of wireless systems for long-range communication between rig and command center. Quality sensor measurement is made possible through industry standard magnetometer and accelerometer packages, including API standardized gamma ray modules. Downhole tool is fully retrievable and reinsertable for added confidence in lost in hole situations. PP-MWD applications are available with the optional rotary flow switch (RFS) that can significantly improve run durations and reduce unnecessary pulser operation by switching tool into standby mode under rotation.
