How deep can a cable tool drill?

In water well drilling, the depth capability for cable tool rigs ranges from 300 to 5000 feet.

What is a cable tool?

1. n. [Drilling] A method of drilling whereby an impact tool or bit, suspended in the well from a steel cable, is dropped repeatedly on the bottom of the hole to crush the rock. The tool is usually fitted with some sort of cuttings basket to trap the cuttings along the side of the tool.

What is the difference between cable tool drilling and rotary drilling?

Although it is a slower drilling method, the cable tool is less costly and simpler to operate than a rotary drill rig and is suitable for most geologic conditions. The cable tool operates by raising and dropping a heavy drill string in the drillhole.

How drilling method is done?

Drilling is a cutting process that uses a drill bit to cut a hole of circular cross-section in solid materials. The drill bit is usually a rotary cutting tool, often multi-point. The bit is pressed against the work-piece and rotated at rates from hundreds to thousands of revolutions per minute.

What is a Spudder rig?

Our Atlas Copco spudder rig, which is designed specifically for drilling surface intervals and running surface casing, helped these clients to save approximately 35 – 40% of their wellbore expenses, enabling them to meet their reduced budget.

What is rotary drilling method?

Rotary drilling is used to form a deep observation borehole or for obtaining representative samples of rock. The drilling method involves a powered rotary cutting head on the end of a shaft, driven into the ground as it rotates.

Is top hammer drilling vs down the hole drilling?

The primary difference between the top hammer and down-the-hole drilling methods is where the hammer is attached. The hammer in the industrial equipment makes contact with the bit during the down-the-hole drilling method. The top hammer drilling method’s activity is concentrated at the very top of the drill string.

What is rotatory system?

The rotary system on a drilling rig is the system that causes the drill bit rotate at the bottom of wellbore.

What is a down-the-hole hammer?

A down-the-hole hammer (DTH hammer) is a tool that can be attached to the end of a drill string and inserted into a bore. It’s a small jack hammer used to break hard rock into small particles that can be flushed away by the DTH hammer’s air exhaust.
