Examination of Hydrocarbon Prospectivity within the Late Tertiary Clastic Section in Offshore Western Greece

Shallow to deep-water carbonates have long been considered as the main reservoir level in the exploration activities in Western Greece. Although, thick (> 1m), good quality sandstone beds do occur within the Oligocene and Miocene clastic section, this interval has only been considered so far in terms of top seal integrity. The identification of several structural and stratigraphic traps within the late Tertiary clastic section in the newly acquired 2D and 3D seismic data from the North Ionian and Kyparissiakos blocks has created the need for the understanding of their reservoir quality and distribution. A comparison between seismic data and outcrop observations is presented in this work, in order to assess the potentiality of these formations to contain adequate reservoir levels.
