1. 3D geological modeling
This stage includes 3D modeling of the structural framework, facial three-dimensional modeling, modeling of petrophysical properties, reserves / resources estimation. Experts of various disciplines are involved to choose the most correct methods for creating models that can be used both in reserves / resources estimation and in planning well programs. Conceptual models, 2D/3D seismic trends, and regional data are used to achieve the result. If necessary, a 3-dimensional DFN fracture model is generated and optimized for the subsequent hydrodynamic modeling. Priority in the work is given to the methods of stochastic modeling, which allows to evaluate various scenarios.
