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.

Disclosed are a method and an apparatus for decoding a signal sent from a measurement-while-drilling tool. In order to decode the signal, a decoder implementation that is communicative according to a decoder implementation protocol and that is configured to decode the signal into a decoded signal is instantiated. The decoder implementation protocol is then conformed to a transmission protocol. The signal is sent to the decoder implementation according to the transmission protocol. Because the decoder implementation protocol has been conformed to the transmission protocol, the decoder implementation can receive the signal and can decode it. One way in which the decoder implementation protocol can be conformed to the transmission protocol is through the use of a translation layer between the module that sends the signal to be decoded and the decoder implementation.

A system for directing the drilling of a well at a drill-site includes an instructing unit, an instructed unit, and a central unit. The instructed unit receives drilling instruction from an instructing driller, sends drilling instructions to the central unit, and presents to the instructing driller drilling instructions and instruction confirmations received from the central unit. The instructed unit receives instruction confirmations from an instructed driller, sends instruction confirmations to the central unit, and presents to the instructed driller drilling instructions received from the central unit. The central unit stores and forwards drilling instructions and instruction confirmations to the instructing unit and instructed unit, and generates and stores slide sheet information from the drilling instructions.
