Brittle structures in porous sandstones, south central Pyrenees, Spain: field characterization and impact for fluid flow
Résumé
In order to better constrain fluids flow circulations in the continental crust, understanding evolution of fault geometry and hydromecanical properties is essential. The knowledge of faulting in analogous reservoirs is particularly important in silicoclastic context. Indeed the high value of natural porosity and the impact of faulting on porosity and permeability will generate potential reservoirs. Depending on the type of faults, deformation in sands and sandstones reservoirs can produces barriers or conduits for fluids.
