Abstract
The peri-platform carbonate clastics extend along the entire Dinarides carbonate platform as slope deposits from Istria offshore in northwest to the offshore Dubrovnik in southeast. These sediments are good potential reservoir rocks of regional extension. This is the first attempt to estimate their hydrocarbon potential.
The mentioned peri-platform deposits extend over 550 - 600 km. Assessment of their reservoir capacity is based on petroleum-geological interpretation of 12 seismic lines crossing transition zone of the Dinarides platform/Adriatic basin. In the studied zone, Tertiary clastics overlay peri-platform slope deposits as regional cap rock while Ladinian-Carnian shales of the Vlasta-1 type represent underlying source rocks, potentially mature in depocenters.
Recent commercial oil discovery in neighboring Rovesti structure at the base of Apulia carbonate platform additionally inspired the authors to make this assessment in the slope zone of the Croatian part of the Dinarides platform. It should be emphasized that our assessment will be in future, most likely corrected by additional interpretation of more cross lines and selected parallel seismic lines.
