1 Investment Energy Summit Greece, Cyprus, Israel Re-designing the European energy map March 28 th -29 th, 2012, Athens Energy exploration in Greece: Its significance for Greece s competitiveness and growth The scientific perspective A synoptic view from Ionian Sea, NW Greece, as far as the SE edge of Mediterranean Sea, in Cyprus, is concerned. Avraam Zelilidis, Professor Department of Geology, University of Patras

3 2/7/2012 Katakolo 3-4 mb Patraikos 200mb Ioannina 50-80mb 1/7/ onshore areas Evros, Kavalla, Serres, Thessaloniki, Grevena, Aitoloakarnania, Messenia, Achaia, Kriti, e.t.c.

4 A C B D The Northwestern part (A), with the red, shows the Apulian platform, the Southern part (B), with the deep blue, show the Mediterranean Ridge, the North Aegean sea (C) with green, show the troughs with Prinos and Epanomi hydrocarbon fields, and (D) Levantine basin with huge oil and gas fields of Cyprus and Israel(modified from Chamot-Rooke et al., 2005).

5 WHAT WE SUGGEST FOR THE NORTHWESTERN PART (A) ( ) APULIAN PLATFORM

6 A1 A2 A3 Geological map with proposed gas and oil plays. The red cycles show: Diapontia islands, Kalpaki area in Ioannina Preveza-Lefkada basin Arta area (modified from Zelilidis et al., 2003).

7 A1 5 billion barrels oil Vlora-Elbasan fault Synthetic sketch map showing Italian and Albanian hydrocarbon plays with an attempt for correlation with the northwestern part of Greece (Diapontia islands). Cross-sections AA and BB based on seismic data.

8 The red dashed lines are seismic lines. The yellow line is the coastline. 1. Internal Albanides, 2. Internal Helenides, 3. Pindos zone (Krasta), 4. Gavrovo zone (Kruja), 5a. Internal Ionian zone, 5b. Middle Ionian zone, 5c. External Ionian zone, 6. Apulian platform: 6a. Plateau Rospo, 6b. Gargano promontory, 6c. Murge ridge, 6d. Salento peninsula, 6e. Apulia plateau, 7. Albanian Alps, 8a. Dures basin, 8b. Ionian-Albania basin, 9. Hellenic trench, 10. Mediterranean ridge, 11. Ionian abyssal plain, 12. Africa, 12a. Hyblean plateau, 13. Calabrian arc, 14. South Tyrrhenian sea, 15. South Apennine.

9 B A C Diapontia Islands with the three potential hydrocarbon regions. A) The first region is north to the Borsh-Khardhiqit fault, B) the second area is located westward to the Ionian thrust - the Ionian foreland basin. The seismic line Northern to Kerkira shows the foreland, C) The piggy-back basins of Ionian thrust There is no detailed offshore research, there is no drill project!!!! OR THERE IS? Petroleum companies are interested in this region The numbers on the seismic line are: (1) Pliocene-Quaternary sediments, (2) Middle-Upper Miocene sediments and (3) Lower Miocene and older formations (modified from Monopolis and Bruneton, 1981).

10 Seismic lines from the region around Corfu island. Proposed potential hydrocarbon fields (pink arrows). The red dashed line shows the Ionian thrust. Oil companies are interested in this region

11 A1 A2 A3 This 3D model is divided into four blocks where the Durres basin, the proportional basins in Diapondia Islands and Preveza, are shown (A1, A2, and A3 circles; Zelilidis et al., 2003).

12 A3 GULF OF PATRAS west east F F Pliocene to present clastics Miocene clastics Mesozoic carbonates F 200 million barrels of oil, according to ministry information based on the Triton results? F

13 BUT WHAT WE HAD FROM FOR THE NORTHWESTERN PART (A)

14 1 2 A We show this map for first time on 4/11/ Ministry published on 4/11/2011 a Map with seismic lines and with boreholes WITH DETAILS FOR Area 1: Diapontia islands Area 2: west of Corfu island Area 3: Preveza Area 4: Patraikos gulf

15 Many seismic lines and few boreholes. WHY? Who knows the results? We are talking for our suggested areas BUT The ministry don want our knowledge don t want our participation don t want our results

16 Diapontia islands West of Corfu Maravelis et. al., 2012

17 WHAT WE SUGGEST FOR THE SOUTHERN PART (B) ( ) MEDITERRANEAN RIDGE- BACKSTOP BASINS

18 Southern Part (B) Bathymetric map of Mediterranean Sea, where Mediterranean Ridge with mud volcanoes, backstop and foreland basins are noted, Maravelis et al., 2012). We know the stratigraphy, the geological evolutionary stages and the basins configuration. We believe that there are both GAS (mostly) and OIL (minor) fields.

19 B1 B2 B3 Southern part: Mediterranean Ridge (modified from Chamot- Rooke et al., 2005), separated into three distinct areas. M.R. H.T ,2: Pliocene and Miocene clastics. 3: Mesozoic carbonates, 4: Triassic evaporites AREA B1: Example from seismic line between Cephalonia and Zakynthos Islands (modified from Kokkinou et al., 2005). The red arrows show the possible hydrocarbon fields

20 Detailed block diagrams from Southern Crete, with mud volcanoes from Olympus field on Mediterranean Ridge, Gavdos, Ptolemeus, Pliny and Stravon basins behind the ridge (modified from Huguen et al., 2006). Mediterranean Ridge in Eastern Mediterranean: AREA B2 is the one with the seven backstop basins trenches (Maravelis et al., 2011). (1) Matapan, (2) Gavdos, (3) Gortys, (4) Ptolemeus, (5) Poseidon, (6) Pliny, and (7) Strabon.

21 AREA B2: An example from the six backstop basins southward to Crete Island (Gavdos, Gortys, Poseidon, Ptolemeus, Pliny and Stravon Trenches) where seismic lines show basin geometry and sedimentary configuration with the presence of Messinian evaporites (Maravelis et al., 2012).

22 Structures that affect AREA B2. Anticlines and Plio-Quaternary depocenters, both onshore and offshore, represent possible hydrocarbon plays (Maravelis et al., 2011).

23 Messara Basin Messara Basin is a restricted basin formed in the northern margins of the Cretan Trench, whereas Gavdos Island is the southern margin of this Trench. Messara Basin sediments, up to 2km thick, mostly Tortonian in age, consist of fine grained sediments, rich in organic carbon, could be the sources for the possible hydrocarbon field of Cretan Trench. Within the Messara basin a biogenic gas field was developed MESSARA BASIN TYMPAKI ASTEROYSIA HIGH

24 BUT WHAT WE HAD FROM FOR THE SOUTHERN PART (B)

25 Ministry published on 4/11/2011 maps with seismic lines and with boreholes WITH DETAILS FOR Area 1: Katakolon field Area 2: Strophades area Area 3: Matapan basin Area 4: Gavdos basin Area 5: Stravon and Pliny basins

26 Many seismic lines and boreholes. WHY? Who knows the results? We are talking for our suggested areas BUT The ministry don want our knowledge don t want our participation don t want our results

34 WHAT WE SUUGEST FOR THE NORTH AEGEAN SEA (C) ( ) TROUGH BASINS

35 C: North Aegean Trough 1. PRINOS HYDROCARBON FIELD North Aegean Trough is related with Prinos (1) and Epanomi (2) fields and as we know the Troughs evolution through the time and in relation to Lemnos island (3), in the southern margins of the trough, we could relate this evolution with possible fields in other places e.g. Mpampouras and Zourafa small islands (4 and 5). 2. SOUTHERN MARGINS - LEMNOS ISLAND

36 BUT WHAT WE HAD FROM FOR THE NORTH AEGEAN SEA

37 A Ministry published on 4/11/2011 map with boreholes WITH DETAILS FOR Area 1: Prinos field Area 2: Epanomi field BUT we show this map for first time on 4/11/2011

38 Really there aren t seismic lines for these areas?? Thasos island Orphanos Gulf

39 Central Greece - onshore Mesohellenic Basin What we know and what we have? We know: Basin history - Basin evolution Basin prospectivity We have: Old seismic data Four wells in wrong places What we need? New seismic lines in proposed areas

41 CONCLUSIONS It seems that it is not a dream but the reality There are many areas where hydrocarbon plays with oil and gas could exist What we need 1. Direct delimitation of the Greek EEZ : Diapontia islands Albania, west of Corfu and west of Zakynthos islands Italy S- SW to Crete island Libya SE to Crete in Herodotus basin Cyprus, Egypt Aegean Sea Turkey 2. Promoting and funding scientific research in the country 3. Open minds and open ears to the scientific knowledge available in the country.
