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.
An underreamer is a device used to enlarge the borehole below an existing casing or restriction, during a well drilling operation. It can be positioned either above the drill bit or above a pilot assembly run inside the existing borehole. Numerous designs exist, in sizes varying from a couple of inches to above 40".
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.
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 ...
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.
Drillers may sink a borehole using a drilling rig or a hand-operated rig. The machinery and techniques to advance a borehole vary considerably according to manufacturer, geological conditions, and the intended purpose. For offshore drilling floating units or platforms supported by the seafloor are used for the drilling rig.
Drilling process for a downhole heat exchanger. Furled tube in the foreground on the left. Bottom end of a downhole heat exchanger Top end of a downhole heat exchanger. A downhole heat exchanger, (DHE) also called a borehole heat exchanger, (BHE) is a heat exchanger installed inside a vertical or inclined borehole. [1]
