A well-logging system includes a downhole tool coupled to a cable. The downhole tool may measure physical parameters of a wellbore via a first plurality of sensors. The well-logging system may include wellbore equipment including a winch. The winch may traverse the downhole tool through the wellbore by spooling or unspooling the cable. The well-logging system may also include a second plurality of sensors that may measure operational parameters of the wellbore equipment. The well-logging system may further include an automation controller that is communicatively coupled to the first plurality of sensors and the second plurality of sensors. A set of defined operating instructions may be prepared during the assembly of the job. The automation controller may control the wellbore equipment based at least in part on feedback from the first plurality of sensors, feedback from the second plurality of sensors, and the defined operating instructions.

Wireline automation systems and methods

Methods and related apparatus pertaining to downhole and surface telemetry, such as a method in which a telemetry system is provided with a communication path formed with an electrically conductive transport medium coupled across a plurality of downhole nodes. Such method includes operating on the communication path with a multi-drop system that provides telemetry to the downhole nodes in a wellbore, including employing modulation in a master-slave arrangement using binary differential phase shift keying or differential quadrature phase shift keying.
