This paper presents a new workflow comprised of using hydraulic fracture modeling outputs (effective length, height, and conductivity) for the next step - a discrete fracture flow model which visualizes the drainage pattern in 3D based on history matched production data. The first part of the paper is designated to fracture forward modeling and prediction of the proppant placement geometry and conductivity of hydraulic fractures in a multistage horizontal well. The influence of wellbore deviations and other local initial conditions are all taken into account and explain localized fracture initiation, fracture asymmetry, and propagation, as well as proppant placement efficiency. The primary model focus is on the creation of fracture conductivity maps, one for each transverse fracture. The second part of this study shows the process of import and conversion of 2D fracture conductivity maps for further use in fluid flow allocation to the individual fractures.
