TL;DR: In this article, a set of four reactive flow-through experiments at temperature T = 100 degrees C and total pressure P = 12 MPa was performed in limestone reservoir samples, with various ranging from 0.7 to 10 MPa, showing non-uniform dissolution features associated with transport-controlled mass transfer, while reaction-controlled uniform dissolution is observed for P-CO2 = 2.5 MPa.

TL;DR: In this paper, the dynamics of porosity and reactive surface area changes during porous limestone dissolution by CO2-rich water were explored, and the numerical model HYTEC was used to model the change in reactive surface areas during the experiment.

TL;DR: The results are used to validate the power law empirical model relating the reactive surface area to porosity proposed by Luquot and Gouze (2009) and investigate the spatial distribution of the effective hydraulic radius and of the tortuosity, two structural parameters that control permeability, in order to explain the different porosity-permeability relationships observed for heterogeneous and homogeneous dissolution regimes.

TL;DR: In this article, the dissolution of a porous limestone core during CO2-enriched water injection was studied experimentally, and the changes in porosity and permeability arising from modifications of the pore network geometry and the fluid-rock interface were measured.

TL;DR: In this paper, a set of four reactive core-flood experiments reproducing underground conditions (T = 100,^{\circ }\hbox {C}\) and \(P = 12\) MPa) has been conducted for different partial pressures (0.034 < P_{\mathrm{CO}_2}< 3.4
