Top 10 Questions for Cable Tool Driller Interview

1. What are the different types of cable tool drilling rigs?

There are three main types of cable tool drilling rigs: standard, rotary, and combination.

• Standard cable tool drilling rigs use a heavy bit attached to a cable to drill the hole. The bit is raised and dropped repeatedly to break up the rock.
• Rotary cable tool drilling rigs use a rotating bit to drill the hole. The bit is attached to a drill pipe which is rotated by a motor.
• Combination cable tool drilling rigs can be used for both standard and rotary drilling. They have a rotating table that can be used to rotate the drill pipe or the cable.

2. What are the main components of a cable tool drilling rig?

• The derrick is a tall, A-shaped structure that supports the drilling equipment.
• The drawworks are a winch that raises and lowers the drilling tools.
• The drilling tools consist of the bit, the drilling stem, and the casing.
• The mud pump circulates drilling fluid through the hole to cool and lubricate the bit and to remove cuttings.

3. What are the different methods of operating a cable tool drilling rig?

• Spudding in is the process of starting the hole. The bit is lowered into the ground and rotated until it drills a hole that is large enough to accommodate the casing.
• Drilling is the process of continuing the hole. The bit is raised and dropped repeatedly to break up the rock and the cuttings are removed by the drilling fluid.
• Casing is the process of lining the hole with pipe to prevent the walls from collapsing.
• Pulling out is the process of removing the drilling tools from the hole.

4. What are the safety hazards associated with cable tool drilling?

• Falling objects can cause serious injury or death.
• Rotating equipment can catch clothing or body parts and cause serious injury.
• Drilling fluid can be hazardous if it is ingested or comes into contact with the skin.
• Noise from the drilling rig can cause hearing loss.
• Vibration from the drilling rig can cause fatigue and other health problems.

5. What are the precautions that should be taken when operating a cable tool drilling rig?
