A new gas field in the Zeus 1 target was discovered in the Cyprus Exclusive Economic Zone (EEZ) by the an ENI-TotalEnergies consortium drilling rig. In fact, this field is larger than the one discovered by on August 22 in the same block (Block 6) by the joint Italian-French consortium.
Preliminary estimates indicate a deposit of 2-3.5 trillion cubic feet, which, when combined with the deposits of Glafkos (5-8 trillion cubic feet), Cronos 1 (2.5 trillion cubic feet), and Aphrodite (4.2 trillion cubic feet), brings Cyprus’ potential capacity to 13.7-18.2 trillion cubic feet, Kathimerini reported.
The Calypso field’s reserves are estimated to be 6-8 trillion cubic feet of gas, but no target has been confirmed so far.
The new discovery in the Cypriot EEZ, which ENI is expected to announce Wednesday, improves the prospects for the exploitation of not only the Cronos 1 field in the same block but also of Glafkos, which is nearby and could become Cyprus’ largest field under certain conditions.
The combined potential of these three fields, according to analysts, can support the 10 billion cubic metres capacity of the East Med pipeline, if, as they point out, “its route is redesigned to approach them and Egypt’s participation in the project is secured in one way or another.”
In any case, the new field strengthens the South-Eastern Mediterranean region’s prospects as a new source of gas supply for Europe, contributing to the continent’s energy independence.
The suspected fields south and southwest of Crete, where ExxonMobil is conducting seismic surveys, are located in the same geological basin.
According to EDEIP data, the geological structures identified in the Ionian and Cretan regions could potentially host reserves of 70-90 trillion cubic feet of gas, enough to cover 15%-20% of EU consumption.
Turkish threats
The Zeus 1 target is the fifth consecutive discovery in the Cypriot EEZ since 2011 when Noble Energy’s drilling rig discovered the Aphrodite field in Block 12, and it comes just four months after the Cronos 1 discovery.
Block 6, where the new deposit is also located, is one of the locations Turkey has mapped as part of its continental shelf, and when it was licensed five years ago, it even threatened a casus belli.
It was described as “a provocative action by the Greek Cypriot administration to offer permission for hydrocarbon exploration and extraction for the so-called Block 6, which lies partly within the outer limits of the Turkish continental shelf in the Eastern Mediterranean” in a document submitted to the UN on 12 April 2017.
It also noted that Turkey “is committed to protecting its sovereign rights, which derive from international law, and will not allow foreign companies to carry out unauthorized hydrocarbon exploration and extraction activities on its own continental shelf.”
Furthermore, following the discovery of “Cronos 1” in August 2022, Ankara was quick to reiterate that it does not recognize Cyprus’ maritime boundaries with Egypt, Lebanon and Israel.
