Removing source wavelet and residual non-uniform absorption (Q) effects can enhance the spatial resolution of seismic images after de-ghosting and amplitude attenuation compensation. In this abstract we propose a new resolution enhancement method that incorporates structural conformity constraints and sparse regularization into an inversion-based deconvolution. The method was applied to field data and compared with an inversion-based approach without sparse regularization and structural conformity constraints. The new method provides a resolution-enhanced broader bandwidth image with improved signal-to-noise ratio and geological coherence. Acoustic impedance inversion was carried out after resolution enhancement, and a more detailed and coherent impedance volume was obtained.
