Seismic modelling of outcrop carbonate systems: an application to the Cretaceous platform-to-basin system of the Maiella Mountain (central Apennines, Italy)

Abstract

AbstractForward seismic models of outcrop analogues are used in hydrocarbon exploration to generate more coherent geological–geophysical models that provide an important scale link between outcrops and seismic survey data. Exploration within slope carbonate plays can be problematic with uncertainties about the reservoir geometries, distribution and volumes owing to complex seismic imaging and lack of closely spaced wells. This seismic modelling study provides a synthetic seismic characterization of the carbonate platform-to-slope-to-basin transition exposed across the Maiella Mountain, central Italy. This outcrop represents an analogue for exploration in carbonate slope strata in the Adriatic offshore area. Integration of original and previously published data allows 2D and 3D geological modelling, providing a better characterization of relationships between the palaeoescarpment and resedimented deposits. The seismic response of the various geological features of this transitional carbonate system is simulated via synthetic seismic modelling using innovative, modern techniques. The seismic simulation was performed in both post-stack-time- and pre-stack-depth-migrated domains. These synthetic seismic models help in understanding and predicting the seismic architecture and character of the palaeoescarpment and resedimented slope deposits.
