Alluvial to lacustrine sedimentation in an endorheic basin during the Mio-Pliocene: The Toro Negro Formation, Central Andes of Argentina [PDF]

open access: yes, 2018
A 2400 m-thick sedimentary column belonging to the Toro Negro Formation was recorded along the Quebrada del Yeso, Sierra de Los Colorados (Vinchina Basin), La Rioja province, NW Argentina. The Vinchina basin is a good example of a closed basin surrounded

The Impact of Rock Morphology on Gas Dispersion in Underground Hydrogen Storage

open access: yesEnergies
Fluid dispersion directly influences the transport, mixing, and efficiency of hydrogen storage in depleted gas reservoirs. Pore structure parameters, such as pore size, throat geometry, and connectivity, influence the complexity of flow pathways and the ...

MOBILITY REDUCTION OF CO2 USING CO2 SOLUBLE SURFACTANTS [PDF]

open access: yes, 2012
Addition of slightly CO2-soluble, brine-soluble, surfactants to high pressure CO2 for EOR may facilitate in-situ generation of CO2-in-brine foams for mobility control.

Lattice-Boltzmann and finite-difference simulations for the permeability for three-dimensional porous media

open access: yes, 2002
Numerical micropermeametry is performed on three dimensional porous samples having a linear size of approximately 3 mm and a resolution of 7.5 $\mu$m. One of the samples is a microtomographic image of Fontainebleau sandstone.

Hydrophobization by Means of Nanotechnology on Greek Sandstones Used as Building Facades

open access: yesGeosciences, 2013
Modern sustainable architecture indicates the use of local natural stones for building. Greek sandstones from Epirus (Demati, Greece, EN 12440) used as building facades meet aesthetic and have high mechanical properties, but the inevitable interaction ...

Mechanical Properties of Sandstone Cement-Stabilized Macadam

open access: yesApplied Sciences, 2019
Application of sandstone in cement-stabilized macadam (CSM) is an effective way to utilize sandstone. To determine the feasibility of using sandstone as a CSM aggregate, a series of experimental investigations, such as unconfined compressive strength ...
