An apparatus and method that form closed-loop system(s) between a downhole system that includes an RSS and a surface control system, to improve stability and performance assurance of the RSS. The apparatus and method account for the actual downhole conditions experienced by the RSS, the actual positioning of the RSS, and historical performance of the surface systems such as the mud pump system, the rotary drive system, and the draw works. These closed-loop systems generate and optimize parameters or target outputs, instructions to surface systems, and instructions for the RSS itself.

Method and apparatus for controlling a rotary steerable system using closed-loop system(s)

A method of identifying an instruction combination executable by a surface control system of a drilling rig to change settings of a rotary steerable system ('RSS') tool. The method includes identifying, by an electronic application, a first current RSS setting of the RSS tool; identifying, by the electronic application, a first target RSS setting of the RSS tool; identifying, by the electronic application, a plurality of instruction combinations configured to change the first current RSS setting to the first target RSS setting. Each instruction combination of the plurality of instruction combinations comprises a number of steps, and each step includes a downlink command sequence. The method also includes selecting, by the electronic application, an instruction combination that comprises the least number of steps.

Methods and apparatus to identify and implement downlink command sequence(s)

A method is provided that can include collecting, via a processor, operational data about a subterranean operation being performed on a rig, determining, via the processor, a type of the subterranean operation based on the operational data, and automatically updating, based on the type, a user display with display elements associated with the subterranean operation.

Automated display of wellbore information

Apparatuses, methods, and systems include rotary drilling a first segment of a wellbore by rotating a drill string with a top drive forming a part of a drilling rig apparatus for a first period of time; obtaining data from a sensor disposed about the drilling rig apparatus while rotary drilling for at least a part of the first period of time; and based on the data from the sensor, determining a proposed oscillation revolution amount for the drill string to reduce friction of the drill string in the downhole bore without changing the direction of a bottom hole assembly while slide drilling.

Drill pipe oscillation regime for slide drilling

Apparatuses, systems, and methods for controlling slide drilling on a drilling rig are described. The methods include detecting current differential pressure of a mud motor and/or weight on bit (WOB) at a surface of a borehole, predicting current reactive torque of the mud motor based on the current differential pressure and/or WOB, and automatically adjusting surface torque and/or angular offset of a tubular adjacent the surface to counteract the current reactive torque and to keep the mud motor at a desired toolface orientation in the borehole.

Automated control of toolface while slide drilling

A system for use in subterranean operations comprising a drill string positioned within a wellbore, a sensor adapted to sense a physical parameter in relation to the drill string and generate a signal representing the physical parameter, and a control member adapted to affect subterranean longitudinal movement of the drill string in a predetermined longitudinal sequence of increments within the wellbore in response to the signal.
