How does a well drilling rig work?
A well drilling rig is a substantial piece of machinery transported to a site by truck and positioned at the location where the well is to be drilled. There are two main types of drilling rigs : rotary drillers and pounders. Rotary drillers use a circular motion to bore into the earth, employing various bits such as long cable bits or interlocking steel bits that rotate clockwise. As the bit turns, it loosens the soil, and rock is brought to the surface. To prevent the drilling bits from overheating, water or mud is often used to keep them cool. On the other hand, a pounder employs cable drilling, raising and lowering a heavy weight to punch holes into the ground. The objective of well drilling is to access an aquifer or water source located deep beneath the ground. However, the drilling process extends beyond reaching the water source to ensure a plentiful and enduring well. For bedrock wells, the drilling depth typically ranges from 100 to 500 feet, and in some instances, i
