It is shown that the key equations of Biot theory can be simplified to storativity equation, based on low … WebIn Biot's theory (Biot 1956a, b), pore fluids are forced to participate in the solid's motion due to inertia and viscosity. The Biot mechanism is described through macroscopic rock properties and based on the macroscopic flow. ... and the isotropic description of the solid/fluid coupling effects developed by Biot . Furthermore, Yang & Zhang ...

WebEDFM is an effective density fluid approximation for the poroelastic model based on the full Biot–Stoll theory. The essence of the approximation is to start by setting the two relatively small frame moduli in Biot–Stoll theory to zero. Then, the effective density can be derived from the equations of motion. WebSep 2, 2024 · Barry et al. used Biot theory and the assumption that material stress is directly proportional to the fluids' frictional forces (i.e., drag) to obtain an analytical solution for the pressure and deformation profiles brought about by a constant point fluid source placed at different depths in the system shown in Figure 9a.
