Miscible Carbon Dioxide Flood Imaging – Analysis of 4D Seismic Wavelet Transform Spectral Composites

Subtlety of 4D seismic anomalies, in carbonates, call upon using high-resolution seismic, which require<br>very demanding tighter cross-equalization standards. We present a non-equalization approach utilizing<br>wavelet transform (WT) spectral components of time-frequency-amplitude analysis of 4D seismic data for<br>both, imaging EOR/sequestration Carbon Dioxide flood in a thin (3-5 m thick) Upper Pennsylvanian<br>oomoldic carbonate reservoir in central Kansas-USA, and for helping to identify fluid-flow controls.
