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
