In August and December 2022, Eni discovered two new gas fields off the country's coast. The first is a reservoir of natural gas under the seabed off Cyprus, thanks to the Cronos-1 exploration well in Block 6, operated by Eni Cyprus with a 50% stake. TotalEnergies is Eni’s partner in the project and holds the remaining 50% stake. The discovery paves the way for the development of new gas resources in the Mediterranean region and is part of Eni's successful efforts to support the supply of additional energy to Europe. Preliminary estimates indicate approximately 2.5 TCF of gas in place, or about 70 billion cubic metres, with significant further potential that will be investigated by drilling an additional exploration well. The second is the result of a discovery made through the Zeus-1 well, which was drilled in Block 6, 162 km off the coast and at a water depth of 2,300 metres. In this case, too, the block is operated by Eni Cyprus, which holds a 50% stake, with TotalEnergies as a partner. Preliminary estimates suggest gas volumes of about 56 to 85 billion cubic metres for the site.

This success was made possible by cutting-edge technology
The discovery of large quantities of gas offshore Cyprus confirms the effectiveness of Eni's exploration strategy, which is based on in-depth knowledge of geological basins and the application of proprietary geophysical technologies, in particular in the field of seismic imaging using the large computing power of the HPC5 supercomputer. The intensive campaign to collect experimental data on the mined material has already shown an overall useful thickness of over 260 metres, with intervals characterised by excellent permeability. Engineering studies for a fast-track development of the project are already under way.

The importance of natural gas in Eni's energy mix
Gas is crucial for energy supply and source diversification. In line with our decarbonisation strategy, its GHG emissions will be progressively reduced.
Natural gas supports the energy transition
Natural gas is important for the security of energy supplies and its Green House Gas emissions will be progressively reduced.
The agreements for the diversification of energy sources
We work closely with producing countries, partners and local institutions to progressively diversify our global portfolio.
Our work in Cyprus
We have been present on the territory since 2013 and hold interests in seven licenses of the country's exclusive economic waters in Blocks 2, 3, 6, 7, 8, 9 and 11, five of which as operators.
