Pressure While Drilling

PWD-2


Bitswave’s PWD section integrates pressure sensor, vibration sensor and speed detection module to measure the mud pressure in annulus and diameter, 3-axis vibration and shock, temperature and stick-slip of drilling tools. It can help operators monitor BHA dynamics in real time and optimize drilling. The measured data can be transmitted to drilling equipment in real time or stored in downhole memory for future analysis.
