Summary We present the application of contemporary processing and imaging algorithms to rejuvenate legacy seismic, with application to a challenging data set from onshore Colombia, characterized by an intricate multi-survey acquisition layout and severe noise contamination in a geologically complex scenario. Implementing tailored noise attenuation and signal enhancement techniques, followed by the first-time merge of the surveys in the area, maximizes the information extracted from the existing seismic data sets. The step forward from time to depth imaging represents a significant, albeit mandatory, improvement towards ensuring structural fidelity and outperforming the available benchmarks in both imaging quality and reliability. As demonstrated by the results achieved by this project, high-end reprocessing and imaging is confirmed as a time- and budget-effective strategy for revitalizing existing assets with the ultimate purpose of minimizing the exploration risk and maximizing recovery.
