The geothermal resources in sedimentary basin are affected by many factors because the characteristic of geothermal reservoirs is very complex, so the heat storage capacities are hard to calculate. This paper took Dunhuang Basin as an example to analyze the geological structure, stratigraphic structure and the formation mechanism of geothermal water based on the formation characteristics of the...

the south khorasan province is located in eastern iran. identifying potential geothermal zones is a pre-requisite for any thermal power plant and recreation center project. geothermal exploration involves a high degree of uncertainty and financial risk, and requires reliable exploration data to constrain development decisions. the present study focuses on identifying the potential zones of geot...

Geothermal investors need to be confident with the methods and results of exploration programs. Also cutting the upfront cost of geothermal exploration will further encourage investors to consider investment in this emerging clean energy field. Hence, it is of paramount importance to improve prospecting techniques in order to explore where economic concentrations of geothermal energy are to be ...

geothermal energy serves as a renewable and clean energy. thanks to its great advantages such as relatively harmless, low costs and environmental friendly, it may be a good substitute for fossil fuels. in the present study, a geothermal survey is conducted in an area prone geothermal ferdows of south khorasan province in eastern iran using etm+ data landsat 7 geo-referenced to topography map in...

Geothermal areas are long recognized to be susceptible to remote earthquake triggering, probably due to the high seismicity rates and presence of geothermal fluids. However, anthropogenic injection and extraction activity may alter the stress state and fluid flow within the geothermal fields. Here we examine the remote triggering phenomena in the Coso geothermal field and its surrounding areas ...

Geothermal energy is one of the cleanest sources of energy which is gaining importance as an alternative to hydrocarbons. Geothermal energy reserves in China are enormous and it has a huge potential for exploitation and utilization. However, the development of the geothermal industry in China lags far behind other renewable energy sources because of the lack of fiscal and taxation policy suppor...

Based on the analysis of geothermal research and utilization, this paper lists the most main challenges of geothermal exploration and exploitation at present in Beijing which is including the lack of regional reconnaissance, the undeveloped of prospecting techniques, the shortened of service life in those geothermal fields which are exploited unreasonably, the unsystematic of dynamic monitoring...

This paper documents the approach used to update the U.S. geothermal supply curve. The geothermal supply curve analysis undertaken in this study estimates the supply of electricity generation potential from geothermal resources in the United States and the levelized cost of electricity (LCOE), capital costs, and operating and maintenance costs associated with developing these geothermal resourc...

Concept of the deep-seated geothermal resources Deep-seated geothermal resources is defined as the depth of 3000-4000m at temperature of approximately 350 degrees C. And it is considered that those deep-seated geothermal resources exist below shallow geothermal reservoirs whch already exploited. 580,000 KW. And it is indispensable to explore geothermal resources " to increase it rapidly. In Jap...

Geothermal energy has many advantages over solar and other renewables. These advantages include: 1) weather-proof; 2) base-load power; 3) high stability and reliability with a capacity factor over 90% in many cases; 4) less land usage and less ecological effect; 5) high thermal efficiency. The total installed capacity of geothermal electricity, however, is much smaller than those of solar energ...
