The ADS utilizes the control capabilities of a PLC with an integrated HMI screen. The result is a powerful system which is both safe and easily operated. ADS controls the drilling tool speed and location based on input from an encoder coupled to the draw works. Input from a dead line transducer is used to control and monitor block load and weight on bit. Input from a mud pressure transducer can be used to control mud motor pressure delta as a drilling parameter. The system includes dual limits for alarm and shut down which operate independently of the function control set points.

The ADS control functions include:

• Weight on bit
• Rate of penetration
• Mud motor pressure delta

We are manufacturer and exporter of driller consoles for our customers. The console is located on the drill floor and contains the control switches for the SCR assignments, rotary table torque limit control and draw works or rotary table reversing.
