Abstract: A system includes a rotatable steerable system (RSS) of a drilling system. The RSS includes a first steering pad, a first fluid actuator coupled to the first steering pad, a first vent passage coupled to the first fluid actuator, a first valve coupled to the first fluid actuator, and a first pressure sensor coupled to the first fluid actuator. The first pressure sensor is configured to monitor pressure of the first fluid actuator as an indication of a health condition of the RSS.

Abstract: A method may include receiving a request to generate a calibrated formation model; responsive to the request, providing an initial formation model, providing field data, generating simulation results using the initial formation model, and performing a comparison between the field data and the simulation results; and, based at least in part on the comparison, generating a calibrated formation model.

Abstract: A flexible downhole component includes an upper connection for connecting the flexible downhole component to a first downhole tool and a lower connection for connecting the flexible downhole component to a second downhole tool. The flexible downhole component includes a flexible body disposed between the upper connection and the lower connection. The flexible downhole component includes an upper damping component and a lower damping component each configured to damp torsional oscillations.

Abstract: A method for evaluating a subterranean wellbore includes rotating a drill string in the subterranean wellbore. The drill string includes a rotary steerable tool, a steerable drill bit, or other rotary steering tool with at least one pad configured to extend radially outward from a tool body and engage a wall of the wellbore. Radial displacements of the pad are measured while rotating and processed to compute a curvature of the wellbore.

Abstract: A directional drilling assembly includes a downhole piston and an uphole piston. A downhole piston diameter of the downhole piston is smaller than an uphole piston diameter of the uphole piston diameter. This may allow the downhole piston and/or the uphole piston to be located closer to the bit, thereby improving the maximum DLS of the system.

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 rotary steerable tool may include a tool body with an upper end and a lower end. Additionally, the tool body may include at least one steering assembly extending from the tool body and includes at least one steering actuator configured to extend beyond other portions of the steering assembly. Furthermore, at least one cutter may be disposed on the rotary steerable tool a distance from the at least one steering actuator.

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.
