CONCLUSIONS

This pilot study indicates that prestack impedance inversion produces P and S impedance information which correlates with the presence of a known gas producing reservoir, at least in a qualitative sense. There is clear potential for mapping spatial changes in reservoir rock properties and pore-fluid constituents from 3-D surface seismic data, which may in turn help production geophysicists and engineers better characterize and understand a given reservoir. Obviously a more quantitative test would need to include detailed well control, reservoir geology and reservoir production data, as is part of my ongoing research.
