Abstract

The paper describes an efficient approach to simulating hydraulic fracturing in Pseudo3D setting for reservoirs with a low permeable matrix. By reformulating the problem, the authors succeeded in reducing it to two ordinary first-order differential equations instead of a nonlinear second-order partial differential equation, which fundamentally affects the computational complexity. Also, this approach allows a more correct computation of a fracture front and fracturing fluids interface versus a traditional Cell-Based Pseudo3D model. Nowadays the main limitation of the developed software module is the absence of matrix leak-off.
