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.
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.
As of 2007 plant construction and well drilling cost about €2–5 million per MW of electrical capacity, while the break-even price was 0.04–0.10 € per kW·h. [10] Enhanced geothermal systems tend to be on the high side of these ranges, with capital costs above $4 million per MW and break-even above $0.054 per kW·h. [42]

As the depth of the holes varied, the drilling of a single well could last nearly one full decade. [4] It was not up until the 19th century that Europe and the West would catch up and rival ancient Chinese borehole drilling technology. [10] [5] For many years, the world's longest borehole was the Kola Superdeep Borehole in Russia.
