In the first couple of months of 2021, the consortium comprising Total, ExxonMobil and Hellenic Petroleum will begin offshore geophysical surveys for hydrocarbons in the blocks to the south and southwest of Crete, according to the formal update it submitted during a video conference with the Regional Authority of Crete last Wednesday.
The winter season is considered preferable for exploration as the reproduction of maritime mammals will be less affected then.
The two blocks, titled “West of Crete” and “Southwest of Crete,” were conceded to the consortium through an international tender announced in 2017 after the companies themselves expressed an interest. The concession contracts were ratified by Parliament last October.
The offshore areas to be surveyed cover a total of 40,000 square kilometers. According to the contracts, the surveying phase will last for eight years and be split into three stages, the last of which will include exploratory drilling.
The first stage concerns geophysical studies and obtaining 3,250 sq.m. of two-dimensional seismic data on the two offshore blocks. That will be followed by the collection of three-dimensional seismic data, and the final stage provides for drilling up to 4 kilometers below the waves.
During the exploratory process the state revenues are estimated at 1.5 million euros in a signature bonus payment and another €2.5 million in surface fees.
The maritime area off Crete is considered a hopeful target for the discovery of hydrocarbons as it has similar geological features to other areas in the Eastern Mediterranean (Cyprus, Israel) where significant natural gas reserves have been discovered. However, due to the great depth, experts say it will take the discovery of considerable quantities of mineral wealth (equal to over 500 million barrels) for its extraction to be financial sustainable.
Before the surveying starts, an environmental management plan will be drafted concerning the application of environmental protection measures, the monitoring process and the drafting of reports. The government must also issue a ministerial decision for the creation of the Regional Observatory of Crete for the Environment and the Safety of the Exploration for and the Utilization of Hydrocarbons.
