It is a common misconception that drilling for water wells is an easy task. In reality, it can be a complicated and time-consuming process. There are many steps involved in the process of drilling a well, and there are several different methods to choose from as well. To help you figure out which method will work best for your needs, we have provided a comprehensive guide on all the different options available to you.

Drilling With Cable Tool Drilling

Most people are familiar with the traditional water well drilling technique using a cable tool. This process is much like you would expect. A drill bit attached to a cable is dropped down the well, and the entire string of pipe containing both the drill bit and additional tools used on-site (i.e., mud pump) is hand-powered to the bottom of your well. Once drilled below ground level, what was once known as an open hole must be cased off to prevent outside contaminants from entering your water source.

Also known as a cable-tool rig or cable tool rig, a cable-tool drilling system uses a length of heavy drill pipe to which a “string” of accessories is attached. The bit assembly on the end of this string includes a cutting shoe and one or more bits with carbide teeth whose rotation is powered by an engine.

Drilling With Air Rotary Drilling

Air rotary drilling uses compressed air rather than cable tool drilling techniques. The drill bit used on this machine runs on an engine that runs pressurized air, which then turns the drill bit (much like how you would get turned around by spinning yourself fast). This process eliminates many of the steps needed to get a well up and running, but it does have its cons. Although there is no need for a cable or casing, setting up an air rotary drilling system can be much more costly.

Drilling With Directional Drilling

Directional drilling has recently become popular because it helps in situations where cable tool drilling or air rotary drilling are not practical. This process uses the same cable used for cable tool well drilling. Still, it also requires the use of a motorized vehicle (usually an ATV) to run the drill bit forward underground, where crews can then install your casing and pump like they would with other options.
