We present the impact of a contemporary processing and imaging sequence in rejuvenating legacy seismic data, demonstrated on a data set acquired in a geologically complex scenario onshore Colombia, characterized by an intricate multi-survey acquisition layout and severe noise contamination. To extract the maximum value from the available measurements, tailored noise attenuation was coupled with signal enhancement techniques. For the first time, the surveys were merged into a single volume and depth-migrated. Moving from time to depth imaging allows capturing the complexities of the wavefield propagation, ensuring structural fidelity, and significantly improving both imaging quality and accuracy. The results demonstrate that reprocessing and imaging employing recent technologies is a time- and cost-effective strategy for revitalizing existing assets with the ultimate purpose of minimizing the exploration risk and maximizing recovery.
