How does a cable drilling rig work?

It is a very old technique, slow but steady and only requires one person to operate the rig. A derrick is raised to support the cable tool. The cable tool is a drilling “bit” that is repeatedly raised and dropped in the hole to break up any formation encountered. Then the cable tool is swapped out and a bailer is lowered into the hole.

What is a cable tool rig?

Cable tool rigs were the first drilling rigs used for hydrocarbon wells. They were used in the United States in the second half of the nineteenth century (1800s) to drill shallow hydrocarbon wells in the Appalachian Region. While these rigs are no longer used in modern oil and gas well drilling, they are of historical note.

The cable tool is a drilling “bit” that is repeatedly raised and dropped in the hole to break up any formation encountered.

What is cable tool drilling?

Principles of Cable-Tool Drilling: At its core, cable-tool drilling involves a simple yet ingenious principle: the repetitive percussive action of a heavy drilling bit driven by a suspended cable. The drill bit, often a chisel-shaped tool, breaks the rock formation through a combination of impacts and rotational movement.

What is a cable percussion drilling rig?

Not ready for a quote? A Cable Percussion drilling rig (otherwise known as Shell and Auger drilling rig) is a mobile tripod rig towed by a 4×4 wheeled drive vehicle.

What equipment do you need for a percussion drilling rig?

Support equipment required for this drilling process are basic, a small truck with welding equipment, torches and a small amount of makeup water. A separately mounted deck engine powers the rig. The cable tool uses the percussion cutting action, utilizing a 1,200 pounds real string, and usually a carbide button bit.
