In-situ cosmogenic 36Cl denudation rates of carbonates in Guizhou karst area [PDF]

open access: yes, 2013
This study quantifies surface denudation of carbonate rocks by the first application of in-situ cosmogenic <sup>36</sup>Cl in China. Concentrations of natural Cl and in-situ cosmogenic <sup>36</sup>Cl in bare carbonates from ...

Pore Type and Porosity Distribution of Carbonate Reservoir Based on 3D Seismic Inversion in “P” Field Salawati Basin [PDF]

open access: yesE3S Web of Conferences, 2019
Overall, carbonate rock has complex and more heterogeneous physical characteristic, compared to siliciclastic sedimentary rock. One parameter, which distinguishes carbonate rock and siliciclastic is pore structure/pore type.

Applying rock mass classifications to carbonate rocks for engineering purposes with a new approach using the rock engineering system

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2017
Classical rock mass classification systems are not applicable to carbonate rocks, especially when these are affected by karst processes. Their applications to such settings could therefore result in outcomes not representative of the real stress–strain ...

A model study of enhanced oil recovery by flooding with aqueous surfactant solution and comparison with theory [PDF]

open access: yes, 2015
With the aim of elucidating the details of enhanced oil recovery by surfactant solution flooding, we have determined the detailed behavior of model systems consisting of a packed column of calcium carbonate particles as the porous rock, n-decane as the ...
