Well drillers use heavy equipment to drill wells for groundwater, oil, or natural gas. They may also work with existing wells and use sonar equipment to locate groundwater. Certification and licensing are often required, and some drillers specialize in deepening existing wells.
Well drillers are professionals who deal with the process of drilling wells that can be developed in various types of wells. A well driller may be hired to drill in a particular location in order to tap a groundwater supply or as a means of extracting oil or natural gas from an underground chamber. In some cases, a well driller works with an existing well that appears to have stopped working properly.
Drilling water wells is not uncommon on farms, ranches, and sometimes even in small towns or communities. With this application, the drilling specialist hopes to obtain a water supply that is not currently being utilized. Today, sonar equipment is often used to identify the position of groundwater reserves, making well drilling much easier to determine the most beneficial location for the well to be drilled or sunk.
Although pit diggers primarily worked by digging pits by hand, this is no longer the case. These days, well drilling jobs include training on using heavy drilling equipment that can be moved into position and used to drill a straight shaft into the ground. Using heavy equipment also makes it possible to create holes that are narrower than manually dug, which is sometimes considered an excellent safety measure.
In terms of training, many well drillers are required to have completed a basic general education in addition to being certified in the use of equipment involved in the trade. Today, many drillers are also certified contractors. However, there are still drillers who learn the trade by learning from an established driller, eventually taking over the existing business or leaving to establish a new drilling business.
As with many professions, well drillers often need to be licensed and bonded before they can offer their services to the general public. Since the early years of the 20th century, national and local associations have sprung up in many countries, enabling well drillers to set standards for their profession and also create training programs that help ensure the proficiency of those entering the field.
There are well drillers who specialize in dealing with existing wells that appear to have gone dry. Often the driller is called upon to deepen the well in hopes of finding another underground vein of water, gas or oil. By employing longer drill axes, it is possible to break the bottom of the existing well and hopefully exploit new resources that will allow the old well to continue functioning.
