Hungary, like other eastern European countries, has suffered from an energy deficit for the past several years. Energy consumption exceeds energy production, and the country remains dependent on mostly imported fossil fuels such as oil and gas. Renewable energy usage is mostly limited to hydro and solar power generation. Government, industry and academia have paid relatively little attention to geothermal energy as a source of heat and power generation. This study aims to identify and examine the feasibility of ha...

The base of the Northern Bohemian region is made up of the kratogen (old block) of the ?Bohemian Massif? that belongs to the so-called Hercynian (Variscan) province. Its development was tectonically terminated by hercynian orogenesis, which means by orogeny in the Palaeozoic Era (Carbon). Such regions are not very promising for the occurrence of geothermal energy, unlike geologically younger areas. But the heat flow is significant in some parts and consequently the area is called the ?Czech geothermal heat flow an...

With the rapid development of Turkey?s petroleum industry, oil production, the way of burning crude oil to produce steam, need to change. Heavy oil reservoir with thin layer or edge water is unsuitable for thermal recovery. Electric heating leads to considerable electrical consumption. Low injection water temperature decreases reservoir temperature and increased crude oil viscosity. The prolonged temperature difference break up reservoir pore throat cement and framework minerals. To improve high-capacity channel c...
