Hellenic Petroleum (ELPE) and Energean have decided to withdraw from their Gulf of Patras license in western Greece, the two companies have informed EDEY, the Greek Hydrocarbon Management Company.

The Gulf of Patras area’s hydrocarbon quantity, believed to measure at least 100 million barrels, will now remain unconfirmed, following this latest development.

In January, 2020, the consortium had applied for an 18-month extension to complete second-phase work at the Gulf of Patras license. At the time, the consortium had cited insufficient port facilities for entry of the project’s drilling facility and other equipment.

The consortium would have had to conduct a first round of drilling this winter or abandon the project. It opted for the latter.

The Gulf of Patras license was originally granted to ELPE through an open-door tender launched in 2012 and completed in 2014.

Italy’s Edison was also a partner but it withdrew and was replaced by Energean.

The project area covers 1,900 square kilometers. Its estimated hydrocarbon reserves, estimated at between 100 and 140 million barrels, had the potential to offer annual turnover of roughly 200 million euros.
