Geologic model building for optimized depth imaging in the presence of Sinú mud volcanoes​

This presentation by TBI and Hocol S.A. outlines an iterative seismic processing and geologic modeling workflow developed to improve subsurface depth imaging beneath onshore mud volcanoes in Colombia’s Sinú fold belt. Because surface mud features create low near-surface coverage, high noise, and severe geologic complexity, the team combined updated near-surface weathering corrections (using ToModel) with iterative Pre-Stack Depth Migration (PSDM). By testing alternative fault interpretations and scanning lower seismic velocities for the subsurface mud body, they eliminated false pull-up structures and significantly enhanced the clarity of underlying Neogene hydrocarbon plays and structural strata compared to legacy 2018 data.
