Water Drilling: information on water drilling and methods

WATER DRILLING Information on Water Drilling and Methods Every year hundreds of thousands of wells are created in the U.S. Although often unnoticed by the public, most of these wells are used towards supplying public drinking water. To create these wells a complicated process of water drilling is implemented, in order to gain access to the hidden water supplies. Over 15 million homes in America have their own water well. DRILLING TECHNIQUES 50% More than fifty percent of wells go towards drinking water. Rotary Drilling Rotary drilling involves attaching a drill bit, made up of tough metals, to a drill pipe. This drill bit is used to crush rocks beneath the ground by rotating as it goes down. Rock cuttings are washed back up the hole by drilling fluids, used to keep the hole from filling in. Down-Hill Air Hammer Down-hill air hammer is a technique which uses compressed air to dig through rocks. It is sometimes preferred when drilling into heavier rocks, and the compressed air also has the added benefit of pushing chunks of loose rock up to the surface. Cable Tool Drilling A third technique is known as cable tool drilling. A heavy drill bit is attached to a wire cable, and then raised and dropped repeatedly to smash the rocks below it. This technique is efficient for the job, but less preferred.
