Abstract: In some aspects, the present invention comprises a system and method for optimizing the control scheme used for drilling operations based on the complex and large data sets available in realtime during operation of a wellsite and based on existing model data available at the wellsite for past similar drilling operations. Such optimizations typically require downtime to quantify how the realtime values will factor into the control model, but the present invention allows for such optimization in realtime in a closed-loop system that will reduce the non-productive time associated with reservoir operations.

Abstract: A stochastic control method includes determining a property of a solid present in a drilling fluid circulating within a mud circulation system and identifying a mud circulation model that dictates operation of the mud circulation system. The mud circulation model is based on one or more models of one or more uncertainties encountered during a wellbore drilling operation. The method further includes determining an accuracy of the mud circulation model based on a difference between the determined property of the solid present in the drilling fluid and a solid property of the drilling fluid as provided by the mud circulation model, and programming a controller of the mud circulation system based on the mud circulation model to modify operation of the mud circulation system.

The mud circulation model is based on one or more models of one or more uncertainties encountered during a wellbore drilling operation. The method further includes determining an accuracy of the mud circulation model based on a residue between the measured fluid property of the drilling fluid and a fluid property of the drilling fluid as provided by the mud circulation model, and programming a controller of the mud circulation system based on the mud circulation model to modify operation of the mud circulation system.

Abstract: An example method for removal of stick-slip vibrations may comprise receiving a command directed to a controllable element of a drilling assembly. A smooth trajectory profile may be generated based, at least in part, on the command. A frictional torque value for a drill bit of the drilling assembly may be determined. The example method may further include generating a control signal based, at least in part, on the trajectory profile, the frictional torque value, and a model of the drilling assembly, and transmitting the control signal to the controllable element.

Abstract: In accordance with some embodiments of the present disclosure, systems and methods for an advanced toolface control system for a rotary steerable drilling tool is disclosed. The method includes determining a desired toolface of a drilling tool, calculating a toolface error by determining a difference between a current toolface of the drilling tool and the desired toolface, decoupling a response of a first component of the drilling tool, calculating a correction to reduce the toolface error based on a model of the drilling tool containing information about a source of the toolface error, transmitting a signal to a second component of the drilling tool such that the signal adjusts the current toolface based on the correction, and drilling a wellbore with a drill bit oriented at the desired toolface.

Abstract: Disclosed embodiments include systems and methods for estimating real-time bit forces experienced on a drill bit and decoupling bit force disturbances. Real-time bit forces can be estimated based on bit force observers using measurements from downhole sensor subs. Model-based observers that adopted to estimate the bit force from downhole sensor sub measurements. Strain and torque measurements as measured by the sensor subs are used to estimate bit force and bit torque. These measurements can be observed using an effective observer design with the estimated bit force and bit torque based on sensor sub measurements to track the real bit force and bit torque. Observations of estimated bit forces and identified bit force disturbances can be used perform drilling dynamics modeling and identify the occurrence of negative drilling events.

Abstract: A system including a plurality of subsystems each of which includes a subsystem controller coupled with a sensor configured to obtain a measurement, an actuator, and a subsystem processor. The subsystem processor includes a first memory storing instructions to identify a subsystem state and generate a subsystem performance objective based on the subsystem state. The system also includes a global processor coupled with each of the subsystems, the global processor includes a second memory storing instructions to identify a global system state based on the subsystem state of each subsystem, generate a global performance objective, calculate an updated performance objective for each subsystem, and transmit the updated performance objective to each subsystem. Once received, the subsystem controller in each subsystem activates the actuator to adjust a subsystem parameter to meet the updated performance objective.
