Zusammenfassung:	A WELL CONTROL METHOD CAN INCLUDE REMOVING FROM A WELLBORE (12) AN UNDESIRED INFLUX FROM A FORMATION INTO THE WELLBORE (12), DETERMINING A DESIRED PRESSURE PROFILE IN REAL TIME WITH A HYDRAULICS MODEL, AND AUTOMATICALLY OPERATING A FLOW CHOKING DEVICE WHILE REMOVING THE UNDESIRED INFLUX FROM THE WELLBORE (12), THEREBY INFLUENCING AN ACTUAL PRESSURE PROFILE TOWARD THE DESIRED PRESSURE PROFILE. ANOTHER WELL CONTROL METHOD CAN INCLUDE REMOVING OUT OF A WELLBORE (12) AN UNDESIRED INFLUX FROM A FORMATION INTO THE WELLBORE (12), DETERMINING A DESIRED WELLBORE PRESSURE WITH A HYDRAULICS MODEL, THE DESIRED WELLBORE PRESSURE PREVENTING FURTHER INFLUX INTO THE WELLBORE (12) WHILE REMOVING THE UNDESIRED INFLUX FROM THE WELLBORE (12), AND AUTOMATICALLY OPERATING A FLOW CHOKING DEVICE WHILE REMOVING THE UNDESIRED INFLUX FROM THE WELLBORE (12), THEREBY INFLUENCING AN ACTUAL WELLBORE PRESSURE TOWARD THE DESIRED WELLBORE PRESSURE.
