摘要： Well pressure control is integrated in real time with geomechanics determinations made during drilling. A well drilling method includes updating determinations of properties of a formation surrounding a wellbore in real time as the wellbore is being drilled; and controlling wellbore pressure in real time as the wellbore is being drilled, in response to the updated determinations of the formation properties. Another well drilling method includes obtaining sensor measurements in a well drilling system in real time as a wellbore is being drilled; transmitting the sensor measurements to a control system in real time; the control system determining in real time properties of a formation surrounding the wellbore based on the sensor measurements, and the control system transmitting in real time a pressure setpoint to a controller; and the controller controlling operation of at least one flow control device, thereby influencing a well pressure toward the pressure setpoint.

摘要： Modeling and triggering safety barriers. At least some of the illustrative embodiments are a non-transitory machine-readable storage medium includes executable instructions that, when executed, cause one or more processors to model, using one or more models, safety barriers in one or more drilling rigs based on drilling rig safety barrier data. The processors are further caused to identify, based on the one or more models, a first impending invalidation of a first safety barrier. The processors are further caused to initialize, triggered solely by the instructions, a second safety barrier based on the impending invalidation.
