Abstract
Methods, systems, and computer-readable media for controlling a toolface of a downhole tool are described. The toolface of the downhole tool, and a toolface setpoint, are determined. Based on the toolface and the toolface setpoint, a toolface error is determined. Based on the toolface error, one or more drilling parameter setpoints are selected from among multiple drilling parameter setpoints. The selected one or more drilling parameter setpoints are adjusted. The adjusted one or more drilling parameter setpoints are inputted to one or more drilling controllers for controlling the toolface of the downhole tool.

A method of controlling a toolface of a downhole tool, comprising:
- determining the toolface of the downhole tool;
- determining a toolface setpoint;
- determining, based on the toolface and the toolface setpoint, a toolface error;
- selecting, based on the toolface error, one or more drilling parameter setpoints from among multiple drilling parameter setpoints;
- adjusting the selected one or more drilling parameter setpoints;
- and
- inputting the adjusted one or more drilling parameter setpoints to one or more drilling controllers for controlling the toolface of the downhole tool,
- wherein the toolface error is indicative of one or more of:
- a magnitude of a difference between the toolface and the toolface setpoint;
- and a direction of a difference between the toolface and the toolface setpoint.
A system for controlling a toolface of a downhole tool, the system comprising:
- a drill string comprising a downhole tool at a downhole end thereof;
- a drill bit connected to the downhole tool;
- and
- a toolface controller for controlling the toolface of the downhole tool, the toolface controller comprising computer-readable memory and one or more processors, wherein the compute-readable memory comprises computer program code configured, when executed by the one or more processors, to cause the one or more processors to perform a method comprising:
- determining the toolface of the downhole tool;
- determining a toolface setpoint;
- determining, based on the toolface and the toolface setpoint, a toolface error;
- selecting, based on the toolface error, one or more drilling parameter setpoints from among multiple drilling parameter setpoints;
- adjusting the selected one or more drilling parameter setpoints;
- and
- inputting the adjusted one or more drilling parameter setpoints to one or more drilling controllers for controlling the toolface of the downhole tool,
- wherein the toolface error is indicative of one or more of:
- a magnitude of a difference between the toolface and the toolface setpoint;
- and a direction of a difference between the toolface and the toolface setpoint.
A computer-readable medium having stored thereon computer program code configured, when executed by one or more processors, to cause the one or more processors to perform a method comprising:
- determining a toolface of a downhole tool;
- determining a toolface setpoint;
- determining, based on the toolface and the toolface setpoint, a toolface error;
- selecting, based on the toolface error, one or more drilling parameter setpoints from among multiple drilling parameter setpoints;
- adjusting the selected one or more drilling parameter setpoints;
- and
- inputting the adjusted one or more drilling parameter setpoints to one or more drilling controllers for controlling the toolface of the downhole tool,
- wherein the toolface error is indicative of one or more of:
- a magnitude of a difference between the toolface and the toolface setpoint;
- and a direction of a difference between the toolface and the toolface setpoint.
