- Designed specifically for mud logging and drilling fluid monitoring.
What Is a Mud Density Sensor
During drilling operations, the mud density directly affects the wellbore pressure and safety. Manual inspection is slow and prone to errors. The CNPS mud density sensor can automatically and in real-time measure the drilling fluid density, eliminating the delay caused by manual sampling. Its differential pressure design can capture precise readings within fixed depth intervals and convert the differential pressure into mud weight data.
The CNPS sensor is specifically designed for integration with mud logging instruments and is capable of withstanding extreme oilfield environments, ensuring that operators maintain accurate mud properties and thereby reducing downtime and drilling risks.
