Patent attributes
Systems and methods for slide drilling are described. The system includes a controller and a drive system. The controller is configured to determine a resonant frequency of a drill string, generate a rotational acceleration profile having a frequency at least substantially similar to the determined resonant frequency, and provide one or more operational control signals to oscillate the drill string based on the generated rotational acceleration profile. The drive system is configured to receive the one or more operational control signals from the controller, and oscillate the drill string based on the generated rotational acceleration profile so that the drill string oscillates at a frequency substantially similar to the determined resonant frequency while slide drilling.
