Abstract: A method for drilling a subterranean wellbore includes rotating a drill string in the subterranean wellbore to drill the wellbore. The drill string includes a rotary steerable tool or a steerable drill bit including at least first and second axially spaced pads configured to extend radially outward from a tool body and engage a wall of the wellbore. Radial displacements of each of the first and second axially spaced pads are measured while drilling. The measured radial displacements are processed to compute a rate of penetration of drilling.

Abstract: A method can include acquiring drilling performance data for a downhole tool; modeling drilling performance of the downhole tool to generate results; training a machine learning model using the drilling performance data and the results to generate a trained machine learning model; and predicting behavior of the downhole tool using the trained machine learning model.

Abstract: A method for drilling a wellbore through a subterranean formation includes rotating a drill string in the subterranean wellbore to drill. The drill string includes a rotary steerable tool or a steerable drill bit including a plurality of pads configured to extend radially outward from a tool body and engage a wall of the wellbore. Radial displacements of at least one of the pads are measured while rotating (e.g., drilling). A formation index is computed while drilling by processing the measured radial displacements, where the formation index is indicative of a strength or hardness of the subterranean formation.
