One of the most promising approaches in deep drilling field is utilization of electrical plasma. It has lower energy efficiency than some other technologies, but it has several other advantages. Producing boreholes with wide range of diameters or drilling in water environment can be mentioned.
A water resources borehole into the chalk aquifer under the North Downs, England at Albury. Engineers and environmental consultants use the term borehole to collectively describe all of the various types of holes drilled as part of a geotechnical investigation or environmental site assessment (a so-called Phase II ESA).
Deep injection well for disposal of hazardous, industrial and municipal wastewater; a "Class I" well under USEPA regulations. [1]An injection well is a device that places fluid deep underground into porous rock formations, such as sandstone or limestone, or into or below the shallow soil layer.
Borehole Mining (BHM) is a remote operated method of extraction (mining) of mineral resources through boreholes based on in-situ conversion of ores into a mobile form (slurry) by means of high pressure water jetting (hydraulicking). This process is carried-out from a land surface, open pit floor, underground mine or floating vessel through pre ...
Water balance. Groundwater recharge or deep drainage or deep percolation is a hydrologic process, where water moves downward from surface water to groundwater. Recharge is the primary method through which water enters an aquifer. This process usually occurs in the vadose zone below plant roots and is often expressed as a flux to the water table ...
