Abstract:
A novel hydraulic fracture scattering simulation method in the hydrocarbon diagnosis is developed in this article. The traditional thin dielectric structure-based surface integral equation (TDS-SIE) is adopted for accurate and stable fracture scattering analysis. To improve the low simulation efficiency of conventional TDS-SIE, a higher order TDS-SIE (HO-TDS-SIE) is developed in this article. The junction vector bases are defined to extend TDS-SIE for the branched fractures. Moreover, the matrix normalization method is adopted to improve the conditioning of impedance matrices and accelerate the convergence rate. The excellent performance of this new HO-TDS-SIE solver for complex hydraulic fracture and network is validated by numerical experiments. To best of our knowledge, this is the first time to extend TDS-SIE into higher order scheme for accurate fracture scattering simulation.
