    Abstract: Methods, systems, and techniques for controlling the rate of penetration of a drill bit are described. In particular, an operate control loop is evaluated by: determining a travelling block acceleration of a travelling block; determining an acceleration error measurement between the travelling block acceleration and a target travelling block acceleration; determining, based on the acceleration error measurement, a brake control signal; and using the brake control signal to control a braking mechanism configured to apply a variable braking force to the travelling block.

    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: 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.

    Abstract: There is described a method for automatically controlling a drilling operation. The method comprises obtaining a recording of one or more controlled drilling parameters adjusted, during a first drilling operation, in response to one or more controlling drilling parameters. The method further comprises, during a second drilling operation subsequent to the first drilling operation, monitoring the one or more controlling drilling parameters. The method further comprises, during the second drilling operation, automatically adjusting the one or more controlled drilling parameters in response to the monitored one or more controlling drilling parameters by using the recording of the one or more controlled drilling parameters. Thus, by recording a driller's instructions once (during a recording phase) and automatically replaying them during successive playback phases, drilling is made more efficient and simpler.
