Heterogeneity and poor connectivity of fractures make it difficult to characterize fracture networks and predict flow behavior on them. Previous studies have introduced inversion models integrating the observed pressure data to describe flow patterns. However, they could not consider the statistical properties of fractures because the models are based on regular lattice or continuum approaches. A new inverse fracture model, which simultaneously integrates fracture characteristics, fluid flow, and solute transport data, is proposed. Discretization for the fracture-occurrence points makes it possible to incorporate fracture properties in the inversion. Fluid flow is implemented by the cubic law, and a semi-analytical method is used to include the solute transport data due to its efficient performance. The model can interpret the characteristics of the geometry and conductivity between wells within fractured reservoirs, since the inverse fracture network not only has the same fracture characteristics as observed data, but also reproduces the fluid flow and solute transport data. It is demonstrated that the fracture network that is developed makes responses for additional flow and transport predicted within a reasonable error range.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
