Well drilling is a massive project that involves the use of heavy-duty equipment to excavate a deep enough hole for the well. A drilling specialist uses a variety of techniques to achieve the desired results. Although each method results in similar outcomes, there are some differences that make each unique. Here are a few tools used for well drilling explained.

3 Methods Used in Water Well Drilling

1. Air Core Drilling

This method uses hollow drill bits that dig into the ground. Compressed air is blown down into the hole forcing drill cuttings back to the surface. While it is an effective drilling method, the blades aren’t strong enough to penetrate rocky soil. 

2. Percussion Rotary Air Blast Drilling

For rugged, rocky terrain, rotary air blasting performs best. A pneumatic hammer with an attached drill bit is slammed into the ground, breaking up the soil and rocks. Air or foam is then used to lift the cuttings out of the hole and push them to the surface. Because rotary blasting drills to extreme depths, it can sometimes hit water, which can flood the hole with dirt and debris. 

3. Auger Drilling

The auger method of well drilling uses a screw-like bit that rotates and pushes its way through the soil. The unique shape of the bit pushes the earth to the surface as the auger drills deeper into the hole. Auger drilling is preferred in softer soil because it does a better job of keeping the hole open as it digs.

Regardless of equipment used, at the end of the process you’ll have a hole ready and awaiting the installation of your well.
