Downhole sensors are used to measure annulus and bore pressure. Pressure can be used to directly calculate Equivalent Circulating Density (ECD), gain a real measurement of the pressure drop along the drill string and through the L/MWD system, and evaluate if the hydraulic power is sufficient to maintain mud motor torque.

Benefits 

• Enables early kick detection from consistent decreases in ECD
• Detects cuttings buildup from increases in ECD
• Gain visibility to the motors ability to transfer power and maintain speed and torque under given conditions
• Can be used in managed pressure drilling applications
• Evaluate the effects of cuttings in the mud column on ECD in fast drilling environments
• Measure pressure drop directly above the mud motor
