Abstract 1D geomechanical model based on cross-dipole wideband acoustic logging for unconventional reservoir is calculated. TIV anisotropic zones were highlighted and corresponding anisotropic elastic properties were confirmed by core samples tests. Final minimal stress profile was calibrated on the data set including log and laboratory studies, drilling and hydrofracturing. Calibrated model was used to optimize frac design for multiple hydrofracing in the horizontal wells.
