E21B44/08 - CPC Classification

Classification description:

Automatic control systems specially adapted for drilling operations, i.e. self-operating systems which function to carry out or modify a drilling operation without intervention of a human operator, e.g. computer-controlled drilling systems ; Systems specially adapted for monitoring a plurality of drilling variables or conditions; Automatic control of the tool feed in response to the amplitude of the movement of the percussion tool, e.g. jump or recoil
