... ABSTRACT: Weakly consolidated sandstone reservoirs generally feature poor cementation, low strength, relatively high porosity and high permeability. Due to the significant effect of poroelasticity, stress redistribution resulting from the pore pressure perturbation around the injection well...

... with identical physico-mechanical properties and representing weakly consolidated sandstone. Using a true-triaxial stress cell (TTSC), the samples were subjected to 3D boundary stresses and radial fluid flow from the boundaries. The fluid flows through the sample uniformly and discharges from a hole drilled...
