Deep Underground Science and Engineering, EarlyView.This study demonstrates the feasibility of an underground closed‐loop thermal storage facility at a post‐mining site, intended for seasonal heat energy storage. Its principal design shows water flow directions in winter and summer (1, 2), heat pumps (3), an upper water reservoir (4), and connecting pipes (5).

New brittleness indexes and their application in shale/clay gas reservoir prediction
Petroleum Exploration and Development, 2015 Aiming at the disadvantages of the brittleness index commonly used in oil/gas exploration, this article proposed two new brittleness indexes (elastic brittleness and mineral brittleness) in order to predict brittle shale distribution accurately: the ...

Estimation of the width of microfractures in shale rocks
Nafta-Gaz, 2015 Anomalous results of permeability for rock samples from shale formations have been analysed. It has been concluded that the microfracture systems present in the examined rocks are the reason of the anomalous values of permeability. Dependences of overburden pressure on fracture permeability have been analysed.

Greenhouse Gases: Science and Technology, EarlyView.ABSTRACT Reliable characterization of mineralogical and textural changes in rock samples is essential for understanding fluid–rock interactions, particularly in experimental studies simulating subsurface conditions. This study presents a reproducible protocol for scanning electron microscopy (SEM) analysis of rock surfaces before and after exposure to ...
