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.
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 ...
Murray & Roberts Holdings Ltd. is a South African-based engineering and mining contractor.It is listed on the JSE Securities Exchange. [3] The Group delivers its capabilities into three global primary market sectors the resources, industrial, energy, water and specialised infrastructure market sectors.
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.
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.
Geothermal Fluid - Gas, vapor and water found within the reservoir; Recharge Area - Area surrounding the reservoir that rehydrates the geothermal system. Exploration involves not only identifying hot geothermal bodies, but also low-density, cost effective regions to drill and already constituted plumbing systems inherent within the subsurface. [3]
Before drilling, the underground geology needs to be understood, and drillers need to be prepared to seal the borehole, including preventing penetration of water between strata. The unfortunate example is a geothermal heating project in Staufen im Breisgau , Germany which seems the cause of considerable damage to historical buildings there.
