Formation temperature is an important parameter in geothermal drilling since it affects drilling fluid, operations and equipment, through mud temperatures. In this study formation temperatures of the five geothermal wells in Germencik-Omerbeyli field were estimated by using mud inlet and outlet temperatures obtained during drilling. GTEMP wellbore thermal simulation model was used to estimate t...

It presents a systematic methodology to evaluate the reservoir characteristics of ChipilapaAhuachapan geothermal field through the highly diluted natural manifestations (springs and domestic wells) in its surroundings. The manifestations are classified in three main groups according to their mechanism of formation: high salinity water (HSW), medium salinity water (MSW), and Sulfated Water (SW)....

There are more than 3000 natural geothermal outcrops in China. The two high temperature geothermal areas in China include the Taiwan geothermal zone and the Himalayan geothermal zone. Low temperature geothermal areas are widely distributed in the vast area of Chinese mainland. The distribution of hot springs, geothermal wells and heat flow are controlled by geological structure. Taking the Ordo...

Poro-mechanical, thermal, and chemical processes can play a significant role when developing enhanced geothermal systems. These processes occur on various time scales and the significance of their interaction varies with the problem of interest. Of particular importance is the thermo-mechanical coupling during injection operations (time scale of months/years). In fact, the phenomena of the vari...

A full-stress, thermomechanically coupled, numerical model is used to explore the interaction between basal thermal conditions and motion of a terrestrially terminating section of the west Greenland ice sheet. The model domain is a two-dimensional flowline profile extending from the ice divide to the margin. We use data-assimilation techniques based on the adjoint model in order to optimize the...

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...

In an effort to tap the vast geothermal resources of the western United States, Secretary of Energy Bill Richardson and U.S. Senator Harry Reid of Nevada recently announced a DOE initiative to expand the production and use of energy generated from heat within the earth. The new initiative is known as GeoPowering the West. During a news conference on Capitol Hill, Secretary Richardson also annou...
