Pressure While Drilling Sensor
The Pressure While Drilling (PWD) Sensor measures the internal bore pressure and the external annulus pressure. Data can be transmitted in real-time via mud pulse or stored in downhole memory for post-well download and analysis, providing a basis for optimizing drilling performance and managing hole cleaning.

Features
● Real-time monitoring of annulus and borehole pressures, enabling early identification of abnormal conditions
● Adjustable sampling rate (up to 2 seconds), supporting downhole storage and surface data playback
● Compact probe design to use with various drill collar sizes, for simple operation and low maintenance
● High-precision pressure calculation supports real-time/post-processing equivalent circulating density (ECD) for hole cleaning and stability analysis
Applications
● Managed pressure drilling (MPD), and underbalanced drilling (UBD)
● Early detection of fluid influx and lost circulation
● Hole cleaning manament
