PGS acquired MultiClient 2D data in Western and Southern Greece for the Hellenic Republic Ministry of Environment, Energy and Climate Change. The program comprised of 12,500km new data acquisition using GeoStreamer with GeoSource and combines re-processing of 9,000km and matching of 13,000km of legacy data into a regional interpretation. The objectives are to improve understanding of regional structure and depositional basins and to identify petroleum systems for the 2nd International Licensing Round, 13 November 2014 to 14 July 2015.
There has been a 15 years break in hydrocarbon exploration in Greece. Most seismic data acquisition and drilling occurred between 1977 and 1987. This activity identified some plays, drilling made one discovery and several wells with shows, but nothing commercial was revealed and the area has been overlooked - until now.
In addition to some long offset and long record-length lines that extend out onto the abyssal plain, the main focus is on three areas.
The northern area is a grid of lines in the Ionian Sea over the Pre-Apulian zone. This zone is an extension of the Southern Adriatic carbonate platform with Late Cretaceous to Eocene basal carbonates overlain by an Oligocene shale seal. These are analogous to the productive fractured carbonate reservoirs of the central Adriatic to the north offshore Italy and Albania.
Further south, offshore western Peloponnese, there is a loose grid of lines around the Katakolon discovery. This area is in the Ionian zone that is analogous to the oilfields onshore Albania. Drilling throughout this zone stopped at or before the Triassic evaporates, these are overlain by thick Mesozoic carbonates and tertiary clastics. Imaging here focus on the Eocene Cretaceous analogs for Katakolon and the Triassic evaporates that hold potential with halite, gypsum and anhydrite interbedded with dolomites and thin organic rich shales.
South of Crete the grid of lines reveals the pre- Messinian accretionary wedge that forms the Mediterranean ridge and the extent of Messinian evaporate coverage.
The full dataset is now available and will be a key asset for evaluation of the offshore prospectivity for the 2nd International Licensing Round (13 November 2014 to 14 July 2015).
Was mich anbelangt, geht es dich nicht an
Aber hoff doch mal, die Geistererscheinung ab und an.
