Regional Evaluation of the Entire Gulf of Mexico Basin—Analysis and Observations

Abstract

Integration of regional 2D seismic and legacy seismic data spanning US and Mexican Gulf of Mexico (GoM) have been merged, reprocessed, repositioned, depth imaged and integrated into a regional basin-wide program. These data provide unique coverage of the entire Gulf of Mexico Basin and its margins imaging the deeper Mesozoic strata and underlying basement over across the basin. Stratal horizons tied to well control in US waters are mapped into Mexican waters, providing an internally consistent stratigraphic correlation of multiple reservoir intervals into unexplored areas of the basin. The mapping and evaluation of seismic character in Tertiary and Mesozoic depositional systems from onshore US Gulf Coast southward to the Bay of Campeche provide the dataset for basin-wide modelling and analysis of different petroleum systems. These data also constrain the position of the continent-ocean transitions in several areas, including the Yucatan rifted margin and the East Mexican transform margin. This analysis forms the basis of a calibrated regional correlation and creates a framework for integration and analysis of other seismic data from the GoM. A number of regional seismic lines and maps are presented highlighting the depositional and structure features and trends for exploration potential in the US and Mexican sectors.
