Abstract
Summary
New field work observations from Zakynthos Island (Ionian Sea, Western Greece) are integrated with modern interpretation of wells drilled on and around the island to better constrain the Cretaceous-Paleoegene carbonate platform.
The exposed Cretaceous shallow water carbonate platform exposed in Zakynthos evidences an assemblage of moderate-sized reefs connected both laterally and vertically by larger lagoonal domains with variable facies. The exposed Paleogene section appear more detrital, with no in-place reef, but with presence of very proximal facies throughout.
The Agios Leon-1 well drilled on top of the Vrachionas anticline onshore Zalynthos drilled through a continuous section of shallow water carbonate from the Cretaceous to the Middle Jurassic. The carbonate fabric is impacted by heavy dolomitization, reducing significanly the porosity as this location. Early observations suggest that this does not impact the Cretaceous shallow water platform found in nearby wells.
More analysis on the wells samples are underway to better constrain the carbonate system.
