This paper introduces a prototype design model for deep low-enthalpy hydrothermal systems. The model predicts, empirically, the lifetime of a hydrothermal system as a function of reservoir porosity, discharge rate, well spacing, average initial temperature of the reservoir, and injection...

The geothermal potential of the Valley of Mexico has not been addressed in the past, although volcaniclastic settings in other parts of the world contain promising target reservoir formations. An outcrop analogue study of the thermophysical rock properties of the Neogene rocks within the Valley...

Geothermal exploration involves a high degree of uncertainty and financial risk, and requires reliable exploration data to constrain development decisions. Geothermal potentials are usually in relation to several parameters such as acidic volcanic and intrusive rocks, volcanoes, faults, hot...

Saudi Arabia is enriched by many geothermal resources that are located along the western coastal part of the Red Sea, in the form of a number of hot springs and many volcanic eruptions. Wadi Al-Lith is considered one of the most promising geothermal targets that encounter many hot springs with a...

The exergy cost structure of the geothermal district heating system (GDHS) is investigated by using an exergoeconomic method called as the modified productive structure analysis (MOPSA). A parametric study is also conducted to show how exergy cost flow rates change with the reference state...

Current situation and trends in geothermal water utilization in Croatia have been analyzed based on data gathering and observations in a period of 16 years with special attention devoted to their use for tourism purposes. Early 2014 geothermal water was utilized at 26 locations (15 springs and...

Sustainable development calls for the use of sustainable energy systems. However, the way in which a geothermal resource is utilized will ultimately determine whether or not the utilization is sustainable. Energy usage is set to increase worldwide, and geothermal energy usage for both...

As the global economy grows, so does the demand for energy. Investment in clean energy projects is increasingly important to help meet these growing energy needs. Clean energy projects are also important for environmental reasons and as part of the battle against climate change. Many clean...

Once all available energy resources of Romania are inventoried, the scientific and business communities must support each other in attaining their common goals to raise the living condition for both themselves, and for the indigenous population, by making the catchment, production and supply of...

Turkey is one of the countries with significant potential in geothermal energy. It is estimated that if Turkey utilizes all of her geothermal potential, she can meet 14% of her total energy need (heat and electricity) from geothermal sources. Therefore, today geothermal energy is an attractive...
