US oil and gas corporation ExxonMobil has been conducting seismic surveys under complete secrecy and at a rapid pace over the past week or so at two offshore block licenses, west and southwest of Crete, held with Helleniq Energy, formerly named ELPE, as its junior partner.

The two blocks share similar geological traits with Egypt’s giant offshore Zohr gas field and, according to early estimates, may contain rich natural gas quantities.

American presence is being assured, through ExxonMobil, in the southeast Mediterranean region at a particularly critical geopolitical period, both because of the Russian invasion of Ukraine and Turkey’s provocative moves against Greece (aggressive rhetoric and the Libya pact), political analysts told energypress.

ExxonMobil acted swiftly to increase its stake in a consortium holding licenses for the two offshore Cretan blocks following a recent  decision by France’s TotalEnergies to withdraw. ExxonMobil acquired TotalEnergies’ share to now hold a 70 percent share in the consortium as the venture’s operator.

The ExxonMobil-led seismic surveys off Crete, which began on October 24, are being conducted by Norway’s PGS and the company’s Sanco Swift seismic vessel. It is conducting 3D surveys, meaning ExxonMobil is focusing on specific areas for possible natural gas deposits.
