Seismic Characterization of the First 3d Surveys Offshore Cyprus and Lebanon

The first 3D seismic data in the deep water offshore Cyprus and Lebanon have been acquired, processed and interpreted. Pre-stack time migration was applied and the 3D data sets have high signal to noise-ratio and very high reflectivity at both shallow and deep levels. Despite the lack of exploration well data a consistent chronostratigraphic framework has been built across Cyprus and Lebanon and implications for prospectivity assessed. Several petroleum systems were identified, and potential prospect types include four-way dip closure structures and stratigraphic traps. Direct hydrocarbon indicators including amplitude and frequency anomalies are associated with many of the identified prospects. Amplitude maps have been extracted on offset stacks, and a good correlation between amplitude anomalies and the closures was found. The recent 3D seismic is considered to reduce the exploration risk in this unexplored frontier area.
