Reconstruction of the Past Climate in Southern Portugal from Geothermal Data [PDF]

open access: yes, 2009
The study of the past climate in the territory of mainland Portugal using geothermal data started in 1996. From an initial set of about 90 temperature logs obtained Portugal, eight were chosen as good for estimating ground surface temperature (GST) in ...

Copper precipitation as consequence of steel corrosion in a flow-through experiment mimicking a geothermal production well

open access: yesGeothermal Energy, 2017
Decreasing production rates and massive precipitation of native copper (Cu(0)) were observed in the production well at the geothermal research facility Groß Schönebeck (Germany). The Cu precipitates filling up the well are a product of an electrochemical

New Geothermal Prospect in North-Eastern Morocco [PDF]

open access: yes, 2010
Geothermal data has been indicating promising potentialities in the north-eastern Morocco. This paperpresents new temperature data, recently recorded in water borehole located in the Berkane and Oujda areas.

Ranking the geothermal potential of radiothermal granites in Scotland: are any others as hot as the Cairngorms? [PDF]

open access: yes, 2017
Prior investigations concur that the granite plutons in Scotland which are most likely to prove favourable for geothermal exploration are the Ballater, Bennachie, Cairngorm and Mount Battock plutons, all of which have heat production values greater than ...

Geothermal Casimir phenomena [PDF]

open access: yesJournal of Physics A: Mathematical and Theoretical, 2008
We present first worldline analytical and numerical results for the nontrivial interplay between geometry and temperature dependencies of the Casimir effect. We show that the temperature dependence of the Casimir force can be significantly larger for open geometries (e.g., perpendicular plates) than for closed geometries (e.g., parallel plates).

Preliminary studies for an integrated assessment of the hydrothermal potential of the Pechelbronn Group in the northern Upper Rhine Graben [PDF]

open access: yesAdvances in Geosciences, 2018
The northern Upper Rhine Graben is due to its tectonic setting and the positive geothermal anomaly a key region for geothermal heat and power production in Europe. In this area the Upper Eocene to Lower Oligocene Pechelbronn Group reaches depths of up

Proposal of a consistent framework to integrate geothermal potential classification with energy extraction [PDF]

open access: yes, 2015
The classification of geothermal resources is dependent on the estimate of their corresponding geothermal potential, so adopting a common assessment methodology would greatly benefit operators, investors, government regulators and consumers.

Modeling of freezing processes by an one-dimensional thermal conductivity equation with fractional differentiation operators

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2017
We have studied the Stefan problem with Caputo fractional order time derivatives. The difference scheme is built. The algorithm and the program for a numerical solution of the Stefan problem with fractional differentiation operator are created.

Impact of operational temperature changes and freeze–thaw cycles on the hydraulic conductivity of borehole heat exchangers

open access: yesGeothermal Energy, 2021
A large share of the primary energy is consumed to provide space heating. Geothermal energy offers a regenerative alternative. For reasons of efficiency and environmental protection, it is important to ensure the system integrity of a borehole heat ...
