The work starts from the analysis of the literature data of the Teapot Dome field in order to determine the fracture mechanisms induced the fracturing. The Cooper and Lorenz, 2011, theory was used as a basis of major fracture dips and azimuth. For the theory proving, the analysis of well with formation microimager (FMI), 48-x-28, was done. This well confirms the theory and the data from previous research (B.C Schwartz) can be used for discrete fracture model construction. As the major STOIIP is included in the matrix, the global geo-cellular matrix model was constructed first Then the several 3D grid sizes were created and the matrix properties were upscaled into the grids. For each grid size model the same discrete fracture model was constructed. The obtained fracture network parameters were upscaled into each grid by means of two methods Oda and Oda gold.
