Abstract: There is described a method of controlling a drilling operation. A pipe joint is determined to be entering a rotating control device (RCD). In response to determining that the pipe joint is entering the RCD, a weight-on-bit (WOB) setpoint is increased so as to increase a measured WOB. After increasing the WOB setpoint, the pipe joint is determined to be exiting the RCD. In response to determining that the pipe joint is exiting the RCD, the WOB setpoint is decreased so as to decrease the measured WOB.

Abstract: There is described a computer-implemented method of controlling a drilling operation. In particular, there is described a computer-implemented method of determining that a differential pressure is in an oscillating state. In response to determining that the differential pressure is in the oscillating state, a weight on bit setpoint is decreased so as to decrease the differential pressure. There is also described a computer-implemented method of determining a difference between a differential pressure and a target differential pressure. The target differential pressure is less than a differential pressure limit. A weight on bit setpoint is adjusted as a function of the difference between the differential pressure and the target differential pressure so as to adjust the differential pressure and thereby reduce the difference between the differential pressure and the target differential pressure.

Abstract: There is described an automated method of detecting a mud motor stall. During a drilling operation, a potential mud motor stall is determined to have occurred, based on drilling parameter data. In response thereto, potential mud motor stall data obtained from the drilling parameter data is compared to stored mud motor stall data associated with mud motor stalls. Based on the comparison, the potential mud motor stall may be confirmed or not confirmed as a mud motor stall.

Abstract: There are described methods, systems, and techniques for performing automated drilling of a wellbore. The wellbore is drilled according to one or more drilling parameter targets associated with one or more corresponding drilling parameters. A controlling drilling parameter of the one or more drilling parameters is determined to be outside a threshold window. In response thereto, one or more controlled drilling parameter targets of the one or more drilling parameter targets are updated. The controlled drilling parameter targets comprise a revolutions per minute (RPM) target and weight-on-bit (WOB) target.

Abstract: Methods, systems, and techniques for performing automated drilling of a wellbore. The wellbore is drilled in response to a first drilling parameter target (such as weight on bit) that includes a first drilling parameter offset modified by a first drilling parameter perturbation signal. A first drilling performance metric (such as rate of penetration) is measured and is indicative of a response of the drilling to the first drilling parameter target. An output of a first objective function is determined using the measured first drilling performance metric. A first correlation between the output of the first objective function and the first drilling parameter perturbation signal, and an integral of the first correlation, are determined. The first drilling parameter target is updated using the integral modified by the first drilling parameter perturbation signal. The wellbore is drilled in response to the updated first drilling parameter target.
