Analysis of the in situ stress contrast impact on a planar hydraulic fracture propagation using the fully coupled poroelastic model

Abstract

In this paper, we use a fully coupled model for 3D planar fracture propagation within a poroelastic reservoir in order to analysis the non-symmetry of the fracture as it develops in a 3-layer reservoir with different compressive stresses in each layer. We demonstrate that the fracture predominantly develops in the layer with the lower compressive stress until it gets arrested due to the equality of the total leakoff to the volume of pumped fluid.
