The improving of seismic images with low illumination is possible a trough the new seismic acquisitions planned using seismic modeling and specific objectives to illuminate in areas where it has “low illumination” -- This work is focused to development a theory to improve the illumination of the subsurface, based in the ray tracing and it having into account the anisotropy effect that both, overburden and geological unit can to print to seismic wave registered -- In the first chapters, we try to rebuild the anisotropic effect increasingly complex analysis to have a geological model representative of a prospective field, which is affected by intense fracturing and this affects the quality of the currently acquired seismic, so we have created a seismic model with HTI anisotropy to evaluate the possibility of improving the quality of a new seismic design that can be added to the existing seismic through a processing flow -- Results show that to use a ray tracer methodology in “ghost zones”, is possible to find a new geometry in surface that really adds the illumination in Problem areas with interest in fracture reservoirs
