The Research centre was officially opened on 10 October 2010 as a result of long-term activities whose aim is to support the geothermal technology research and development in Slovakia. In October 2012, GA Drilling officially moved from Research Center for Deep Drilling to newly founded GA Drilling Technology Center. High-energetic electrical plasma High-energetic electrical plasma is a promising technology which is currently being developed in deep drilling applications. It has lower energy efficiency than some of the other technologies, but has several other advantages.

Plasma Deep Drilling Technology
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. High-energy plasma High-energy plasma is a technology that targets deep drilling applications. It addresses issues related to drilling in water environments or boreholes with varying diameters. Physical principle of electrical plasma An electric arc is a breakdown of a gas that produces a plasma discharge, resulting from a current flowing through normally nonconductive media such as air or another gas. An arc discharge is characterized by a lower voltage than a glow discharge, and relies on thermionic emission of electrons from the electrodes supporting the arc. The electric arc is influenced by factors such as: the gas flow, inner ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geothermal Anywhere
GA Drilling (formerly ''Geothermal Anywhere'') is a drilling and geothermal energy company in Bratislava, Slovakia with branches in Bristol (UK), Abu Dhabi (UAE), and headquartered in Houston (US). The company was founded in 1994 and rebranded as GA Drilling in August 2013. GA Drilling is also active within the drilling community through participation in several industry events. Technology Plasmabit Plasmabit is a pulsed plasma drilling system. A rotating plasma torch uses ionized gas at 6,000 °C (10,800 °F) to crack and weaken the rock, while high-pressure water mechanically removes rock chips and flushes them to the surface. Anchorbit Anchorbit progressively moves the borehead deeper into the well. It consists of two stacked collar sections behind the drill bit. Each section has four ranks of pistons that can extend and grip the bore shaft. The sections can move independently. While one section grips the bore, the other moves closer to the drill bit. Then the moving se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slovak Academy Of Sciences
The Slovak Academy of Sciences ( sk, Slovenská akadémia vied, or SAV) is the main scientific and research institution in Slovakia fostering basic and strategic basic research. It was founded in 1942, closed after World War II, and then reestablished in 1953. Its primary mission is to acquire new knowledge of nature, society and technology, specifically targeted at ensuring scientific basis for the advancement in Slovakia. It comprises 58 scientific institutes and 13 ancillary institutions. The SAV edits 44 scientific and scholarly journals and 100–120 monographs per annum. Moreover, 41 scientific and scholarly societies, which associate scientists and scholars from various disciplines, are affiliated with SAV. History The commencement of modern science in the 16th and 17th centuries resulted in the establishment of new institutions that supplemented classical universities and created a broader forum for fostering science communication. These institutions, which were bui ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plasma (physics)
Plasma ()πλάσμα , Henry George Liddell, Robert Scott, ''A Greek English Lexicon'', on Perseus is one of the four fundamental states of matter. It contains a significant portion of charged particles – ions and/or s. The presence of these charged particles is what primarily sets plasma apart from the other fundamental states of matter.

Enhanced Geothermal System
An enhanced geothermal system (EGS) generates geothermal electricity without the need for natural convective hydrothermal resources. Until recently, geothermal power systems have exploited only resources where naturally occurring heat, water, and rock permeability are sufficient to allow energy extraction. However, by far the most geothermal energy within reach of conventional techniques is in dry and impermeable rock. EGS technologies enhance and/or create geothermal resources in this hot dry rock (HDR) through a variety of stimulation methods, including 'hydraulic stimulation'. Overview When natural cracks and pores do not allow economic flow rates, the permeability can be enhanced by pumping high-pressure cold water down an injection well into the rock. The injection increases the fluid pressure in the naturally fractured rock, triggering shear events that enhance the system's permeability. As long as the injection pressure is maintained, a high matrix permeability is n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New Drilling Technologies
The latest study of Massachusetts Institute of Technology "The Future of Geothermal Energy – Impact of Enhanced Geothermal Systems (EGS) on the United States in the 21st Century" (2006) points out the essential importance of developing an economical deep geothermal boring technology. With current boring technologies, bore price rises exponentially with depth. Thus, finding a boring technology with which the bore price rise would be approximately linear with increasing bore depth is an important challenge. New drilling technologies requirements This MIT study characterizes the requirements on new fast and ultra-deep boring technology as follows: *the price of boring rises linearly with depth *bore axis with neutral floating *the possibility to make vertical or inclined bores up to 10 km deep *the possibility to make large diameter bores – even 5 times larger than on the ground compared to today drilling technologies *casing formed on site in the borehole Examples There a ...

Drilling Technology
Drilling is a cutting process where a drill bit is spun to cut a hole of circular cross-section in solid materials. The drill bit is usually a rotary cutting tool, often multi-point. The bit is pressed against the work-piece and rotated at rates from hundreds to thousands of revolutions per minute. This forces the cutting edge against the work-piece, cutting off chips (swarf) from the hole as it is drilled. In rock drilling, the hole is usually not made through a circular cutting motion, though the bit is usually rotated. Instead, the hole is usually made by hammering a drill bit into the hole with quickly repeated short movements. The hammering action can be performed from outside the hole ( top-hammer drill) or within the hole ( down-the-hole drill, DTH). Drills used for horizontal drilling are called drifter drills. In rare cases, specially-shaped bits are used to cut holes of non-circular cross-section; a square cross-section is possible. Process Drilled holes are ...

Geothermal Drilling
A ground source heat pump (also geothermal heat pump) is a heating/cooling system for buildings that uses a type of heat pump to transfer heat to or from the ground, taking advantage of the relative constancy of temperatures of the earth through the seasons. Ground source heat pumps (GSHPs) – or geothermal heat pumps (GHP) as they are commonly termed in North America – are among the most energy-efficient technologies for providing HVAC and water heating, using far less energy than can be achieved by burning a fuel in a boiler/furnace or by use of resistive electric heaters. Efficiency is given as a coefficient of performance (CoP) which is typically in the range 3 – 6, meaning that the devices provide 3 – 6 units of heat for each unit of electricity used. Setup costs are higher than for other heating systems due to the requirement to install ground loops over large areas or drill bore holes, and for this reason air source heat pumps are often used instead.
