Adapting the explicit time integration scheme for modeling of the hydraulic fracturing within the Planar3D approach

Abstract

This work is devoted to the model of hydraulic fracture propagation in a layered medium based on the Planar3D approach. The key features of the proposed model are to reduce the system of partial differential equations to a dynamic system, as well as apply universal asymptotes for determining the position of the crack front. We compare calculations with published results of ILSA and EP3D models and discuss methods for accelerating calculations and the possibility of taking into account additional effects (proppant transfer, elastic modulus contrast).
