Abstract

A method of controlling pressure in a wellbore (12) can include determining a desired well pressure setpoint, adding an offset to the setpoint in response to an actual well pressure deviating from the setpoint by a predetermined amount, and adjusting a flow control device (74, 76, 78, 81, 160), thereby influencing the actual well pressure toward the setpoint plus the offset. A well system (10) can include a flow control device which variably restricts flow from a wellbore, and a control system (90) which determines a desired well pressure setpoint, compares the setpoint to an actual well pressure, and adds an offset to the setpoint in response to a predetermined amount of deviation between the setpoint and the actual well pressure, whereby the control system adjusts the flow control device, and thereby influences the actual well pressure toward the setpoint plus the offset.
