Objectives :
Measure the effect of the alteration on the petrophysical properties, in well-constrained conditions.

Description of planned work :
Prior and posterior to each experiment, X-ray CT scans and petrophysical characterization will be performed (see WP1). Mineralogical analysis of the pre and- post-mortem samples will allow to evaluate the minerals prior and posterior to the reactions of alteration, and to identify the reaction at stake in the alteration process. Acquisition will be performed on both Montpellier and ISTerre post-mortem samples. The comparison of the 2 datasets acquired in parallel will highlight the difference of advancement of alteration between the 2 stress configurations.
