The European Bank for Reconstruction and Development (EBRD) signed a $20 million loan deal with Greece's privately-owned Energean Oil & Gas, the country's sole oil producer, to support existing and new projects, it said.

Energean, 45% owned by U.S. hedge fund Third Point, has an output of more than 4,000 barrels per day (Mbbl/d) from two oil fields in the Prinos Basin off of the northern Greek island of Thassos.

Energean said there are an estimated 30 MMbbl of proven and probable oil reserves in the Prinos Field. Under the same license, it has 28 MMbbl of contingent resources where significant exploration potential was identified in 3-D seismic surveys in 2015.

The EBRD said the financing follows a $75 million loan, agreed with Energean earlier this year, related to investment and development of the Prinos Field.

The new loan will also support the introduction of new technology, investments to avoid gas flaring, and several resource efficiency investments to optimize the supply and use of energy, the EBRD said in a news release.

Energean said there is also potential from ongoing exploration activity in the onshore Ioannina and offshore Katakolon blocks in western Greece, and from a 2-D seismic survey conducted in Egypt earlier this year.

The EBRD started investing in Greece in 2015.
