Abstract
A system and method can include a module including at least one actuation assembly configured to transition between an inactive configuration and an active configuration. The system include at least one sensor configured to obtain data that is indicative of an operating parameter, and at least one processor configured to be electronically coupled to the guidance module and the at least one sensor. The at least one processor is configured to, in response to 1) input received from the at least one sensor that is indicative of the measured operating parameter, and 2) received input that is indicative of an actual drilling direction that is deviated from the predetermined drilling direction, adjust an extent that the actuation assembly is in the active configuration.
Claims23
A method for guiding a direction of a drill bit coupled to a drill string, the method comprising the steps of:
- rotating the drill bit to drill a borehole in an earthen formation according to a predetermined drilling direction;
- determining if an actual drilling direction that the drill bit is drilling the borehole is within a predetermined threshold of the predetermined drilling direction;
- if the actual drilling direction is not within the predetermined threshold of the predetermined drilling direction, actuating at least one actuation assembly of a rotary steerable motor system from an inactive configuration into an active configuration to increase a force applied to the wall of the borehole by the at least one actuation assembly so as to redirect the drill bit toward the predetermined drilling direction;
- measuring with a pressure assembly a differential pressure across an inlet and an outlet of a pump of the rotary steerable system when the actuation assembly is in the active configuration;
- and
- determining if the differential pressure varies from a predetermined value;
- and
- automatically adjusting an extent that the at least one actuation assembly is in the active configuration as the differential pressure varies from the predetermined value so as to control redirection of the drill bit toward the predetermined drilling direction.
A method for controlling a direction of a drill bit coupled to a drill string, the method comprising the steps of:
- causing the drill bit to drill a borehole into the earthen formation along a predetermined drilling direction;
- guiding the drill bit with a rotary steerable motor system according to one or more steering parameters toward the predetermined drilling direction during formation of the borehole in response to any determined deviations between an actual drilling direction and the predetermined drilling direction;
- and
- correcting the steering parameters based on one or more operational parameters of the rotary steerable system, wherein the one or more operational parameter is a differential pressure of a pump in the rotary steerable motor system.
