Abstract

The study of seismic anisotropy and the different effects associated with it is the subject of advanced research for geophysicists engaged in unconventional and fractured reservoirs. Seismic anisotropy can be caused by various geological reasons, often the reason for this is the presence of the fracture interval or differences in the horizontal stresses in particular geological section. Indeed, in both cases, taking into account the causes of seismic anisotropy will have a significant impact on exploration drilling, field development optimization plans, etc. This paper presents the possibility of using the results of the interpretation of the azimuthal inversion to optimize development plans for low-permeability reservoirs. The elastic properties delivered by the anisotropic inversion are very useful to update the results of reservoir characterization. Predicted azimuth of maximum horizontal stress is valuable information for the planning of horizontal wells. For successful implementation of fracking in horizontal wells wellbore must have a direction perpendicular to the azimuth of maximum horizontal stress. Overall anisotropy parameters are key factors in identifying perspective areas and setting of horizontal wells
