Abstract: During drilling of a wellbore, in a predicting state, a drilling parameter is monitored and, based on the monitored drilling parameter, it is determined that the drilling parameter is likely to exceed a drilling parameter setpoint associated with the drilling parameter. In a mitigating state, in response to determining that the drilling parameter is likely to exceed the drilling parameter setpoint, a rate of penetration setpoint is reduced so as to mitigate a likelihood of the drilling parameter exceeding the drilling parameter setpoint. In addition, during the drilling, drilling parameter data is received. A controller is used to generate, based on the drilling parameter data, one or more drilling parameter setpoint recommendations. At least one drilling parameter setpoint recommendation is selected. The selected drilling parameter setpoint is provided to an automated drilling unit that is separate from the controller.

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 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.
