Application of seismic boundary-preserving constrained inversion for delineating reservoir body

Delineating reservoir units is still a challenge for seismic studies. In this paper, we propose to use seismic crosswell inversion with a new boundary-preserving constraint for delineating the ambiguous geometry of a reservoir. The advantage of boundary-preserving constrained inversion is to preserve the geologic boundary of target reservoir. Firstly, we use synthetic examples to verify the methodology in comparison with those of conventional smoothly constrained inversion. Then we apply this boundary-preserving inversion method to field data. We found that the boundary preserving constraints improve image quality by preserving the expected boundaries - top and base of reservoir.
