Nearly 175 community members joined a town forum Nov. 3, held in person and online, to hear updates on the Cornell University Borehole Observatory – known as CUBO. The observatory represents a major s...
Cornell is one step closer to determining the feasibility of using deep geothermal energy to heat the Ithaca campus.
Swelling colloids – mixtures, such as milk and paint, in which particles are suspended in a substance and which can grow up to 100 times larger under certain temperatures – could be used to fix flow p...
Analysis on variation characteristics of geothermal response in Liaoning Province
Average initial formation temperature Average thermal conductivity Formation temperature recovery Thermal response Liaoning Province

Due to energy shortage and increasing environmental awareness, resources in shallow underground space have been rapidly exploited and utilized. So that studying variation characteristics of geothermal...
Research on the fault controlling mechanism of geothermal water in Zhangzhou Basin
faulted structure Hydrothermal activity Geothermal reservoir temperature Circulation depth
2018/3/23
Fault has an important influence on the storage and movement of geothermal water. The Zhangzhou Basin is wholly located in a granodiorite rock mass. Due to the low permeability of granodiorite, faulte...
Clogging mechanism in the process of reinjection of used geothermal water: A simulation research on Xianyang No.2 reinjection well in a super-deep and porous geothermal reservoir
Xianyang Super-deep and porous geothermal reservoir Reinjection Clogging mechanism

CO2 is now considered as a novel heat transmission fluid to extract geothermal energy. It can be used for both energy exploitation and CO2 geological sequestration. Here, a 3-D, “two-spot” pattern wel...
Thermal stresses analysis of casing string used in enhanced geothermal systems wells
Casing deformation and collapse Pre-tension stress cementing Well completion design Pre-stressed cementing
2018/3/23
In the enhanced geothermal systems wells, casing temperature variation produces casing thermal stresses, resulting in casing uplift or bucking. When the induced thermal stresses exceed casing material...
