Abstract

The observation of a seismic profile in the offshore of South East Italy outlined the presence of a clear reflector, about 10 km long with prominent negative amplitude and gentle anticlinalic shape: probably it represents a bright spot, connected with the presence of a gas level in the Plio-Quaternary sequence. Below this series the Eastern Apulia carbonate platform margin was interpreted; it represents an important feature for the migration and the accumulation of fluids in the covering sediments. There are not boreholes reaching the bright spot, so we decided to re-process the seismic profile in order to better classify the real origin of this reflector. The AVO technique was used for pore fluids identification and the results were integrated with other seismic attributes analysis, such as instantaneous seismic attributes, and with spectral decomposition analysis. The results confirm the possibility that the considered bright spot may represent a gas saturated level, so we followed this horizon along the public seismic lines of the surrounding region. The mapping of the reflector evidenced the presence of a wide possible gas-reservoir developing toward the inner sector of the Apulia platform, so it could be taken into account for a dedicated survey.
