Estimation of cement thermal properties through the three-phase model with application to geothermal wells [PDF]

open access: yes, 2018
Geothermal energy has been used by mankind since ancient times. Given the limited geographical distribution of the most favorable resources, exploration efforts have more recently focused on unconventional geothermal systems targeting greater depths to ...

Technological Advancements and Challenges of Geothermal Energy Systems: A Comprehensive Review

open access: yesEnergies, 2022
Geothermal is a renewable energy source, but this is not as often seen as other renewable energy sources, such as solar, wind, hydro, etc. Several applications could be implemented through geothermal energy, and heating & cooling systems are one of them.

Workshop “Geothermal fluids in saline systems”

open access: yesGeothermal Energy, 2017
Earth’s crust offers a vast resource of heat that can be used and converted into energy both for electricity and heating/cooling purposes. The utilization of this geothermal energy can make an important contribution to meet the targets of the envisaged ...

Cap rock efficiency of geothermal systems in fold-and-thrust belts: Evidence from paleo-thermal and structural analyses in Rosario de La Frontera geothermal area (NW Argentina) [PDF]

open access: yes, 2016
Cap rock characterization of geothermal systems is often neglected despite fracturing may reduce its efficiency and favours fluid migration. We investigated the siliciclastic cap rock of Rosario de La Frontera geothermal system (NW Argentina) in order to

The Carbon Dioxide Emission as Indicator of the Geothermal Heat Flow: Review of Local and Regional Applications with a Special Focus on Italy

open access: yesEnergies, 2021
We review the methods based on the measurement of CO2 emissions for the computation of geothermal heat flow, both at a local (hydrothermal sites, a few km2) and regional scale (hundreds km2).

2014 JRC Geothermal Energy Status Report [PDF]

open access: yes, 2014
Geothermal energy resources have been used by mankind in some form for thousands of years. Depending on the temperature of the resource, it may be used for power production, supply of heat or a combination of both. This report presents the current status

Lassen geothermal system [PDF]

open access: yes, 1982
The Lassen geothermal system consists of a central vapor-dominated reservoir underlain by hot water that discharges peripherally at lower elevations. The major thermal upflow at Bumpass Hell (elevation 2500 m) displays numerour superheated fumaroles, one of which in 1976 was 159/sup 0/C.

Injection-Triggered Occlusion of Flow Pathways in Geothermal Operations

open access: yesGeofluids, 2018
Reasons for injectivity decline were investigated in a low-enthalpy geothermal aquifer in Klaipeda (Lithuania). It is one of the study sites within the DESTRESS project, which demonstrates different stimulation techniques in geothermal reservoirs. Due to
