ANNULUS PRESSURE SETPOINT CORRECTION USING REAL TIME PRESSURE WHILE DRILLING MEASUREMENTS

A method of controlling pressure in a wellbore can include determining a real time wellbore pressure PwbRT1 at a pressure sensor in the wellbore, calculating hydrostatic pressure Ph1 at the pressure sensor, determining a real time annulus pressure PaRT, calculating friction pressure Pf due at least...
