Producing boreholes with wide range of diameters or drilling in water environment can be mentioned. The research team from Slovakia has developed drilling concept based on utilization of electrical plasma. The core of the research is held in Research Centre for Deep Drilling which was opened in the premises of Slovak Academy of Sciences.
A downhole heat exchanger, (DHE) also called a borehole heat exchanger, (BHE) is a heat exchanger installed inside a vertical or inclined borehole. [1] It is used to capture or dissipate heat to or from the ground. DHT's are used for geothermal heating, sometimes with the help of a geothermal heat pump.
Quaise, Inc was founded in 2018 to develop a millimeter-wave drilling system for converting existing power stations to use superdeep geothermal energy. [1] The system would repurpose existing gyrotron technology to drill 20 kilometers beneath the surface, where temperatures exceed 400°C.
Plasma deep drilling technology is one of several drilling technologies that may be able to replace conventional, contact-based rotary systems. These new technologies include plasma deep drilling, water jet, hydrothermal spallation and laser. Companies that embrace plasma-drilling method include GA Drilling, headquartered in Bratislava, Slovakia.

R&D network. GA Drilling has created or is a co-founder of the network of technology organizations in the European Union, mainly in the Central European region. [5] Its partner network consists of Slovak (Slovak University of Technology, University of Zilina, Comenius University, institutes of the Slovak Academy of Sciences) and European organisations (Weatherford UK Ltd, [6] Imerys, [7] EGS ...
Geothermal drilling is the process of creating boreholes in the earth to extract the earth's heat. Pages in category "Geothermal drilling" The following 6 pages are in this category, out of 6 total.
The space between the wall of the borehole and the U-shaped tubes is usually grouted completely with grouting material or, in some cases, partially filled with groundwater. [15] For illustration, a detached house needing 10 kW (3 ton) of heating capacity might need three boreholes 80 to 110 m (260 to 360 ft) deep. [16] Radial or directional ...
