WebConsolidation theory describes the transient process, where pore pressure equilibrium is re-established after a change in the stress state. This process involves a flow of the pore fluid through the porous rock. Viscous flow in porous rocks is described by Darcy's law, which states that the fluid flow rate Q → (fluid volume per unit time flowing through a …
