Mechanical Compaction of Porous Sandstone: An Experimental Study Using Acoustic Emission (AE) Monitoring
AE Monitoring during Compaction of Sandstone
In some reservoirs, large deformations occur during oil or gas production because of the effective stress change. For very porous rocks, these production operations can be sufficient to cause inelastic deformation and irreversible damage. Rock formations can undergo deformation by different mechanisms, including dilatancy or pore collapse. In the laboratory, the spatial evolution of damage as well as the source mechanism can be followed using the acoustic emissions. In this paper, we present three different laboratory axisymmetric compression experiments. Indeed, when subjected to an overall compressive loading, a porous rock may fail by shear localisation, compaction localization, or by cataclastic flow.
