Well Drilling is the process of drilling a hole in the ground for the extraction of a natural resource such as ground water, natural gas, or petroleum. Water well drillers sink wells into the surface of the earth in order to gain access to natural water supplies. Types of water wells include agricultural wells used for irrigation, commercial or industrial wells for manufacturing or other business process needs, and wells that provide a drinking water supply for homes which are not connected to a municipal water system.
The development of well drilling techniques
The earliest water wells were shallow pits dug by hand in suitable areas where the water table was relatively close to the earth’s surface. These wells were normally lined with rocks or wood to prevent collapse. Modern well drilling techniques use long drill shafts that create much narrower and deeper passages than possible by digging. As the well drilling shaft bores beneath the surface into the ground, the shaft is usually lined nowadays with steel or plastic pipe to prevent collapse.
The process of well drilling usually requires the hiring of a workforce crew made up of well driller helpers and pump service rig operators and helpers. They set up a truck-mounted or foundation-mounted derrick (rig) with the drilling apparatus and other required equipment. Various rig sizes are manufactured for different hole sizes and depths. Many of the water well drillers are also drilling geothermal heating and cooling wells.
Well drilling for your project
Recent innovations have led to a specialized form of well drilling using HDDW’s that provides the possibility to simultaneously filter and extract water from underground sources, which greatly simplifies the process. HDDW’s result in a substantial cost savings over conventional well drilling, requiring fewer water pumps and conveyance pipes. They can be used for a variety of groundwater extraction applications, such as for drinking water, industrial needs or purification as part of a soil remediation strategy. Another advantage is that HDDW’s require less space for installation and therefore can be used to extract water under a greater range of geographical and geological conditions.
