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.
