TotalEnergies and Eni Greenlight Cronos Gas Field Development, Cyprus’ First Offshore Gas Project

Strategic Go-Ahead for Cyprus’ First Offshore Gas Development

TotalEnergies SE and Eni have jointly announced the Final Investment Decision for the Cronos gas field development in the Eastern Mediterranean. Discovered in 2022 and appraised in 2024, the Cronos field marks a significant milestone as Cyprus’ first gas development project. Located approximately 185 kilometres southwest of the Cypriot coast in deep offshore waters, the field will be developed through four subsea wells as part of a phased approach to unlock reserves in Block 6.

The project follows the signing of a Host Government Agreement in February 2025, establishing the commercial and contractual framework necessary for development. This approval highlights collaboration among TotalEnergies, Eni, and the governments of Cyprus and Egypt to establish a regional gas hub in the Eastern Mediterranean. TotalEnergies holds a 50% stake while Eni operates the field, reflecting a strategy of engaging in major projects while leveraging experienced operators.

Production Schedule and Capacity for Eastern Mediterranean Gas Supply

Production from the Cronos gas field is expected to start in 2028, reaching a plateau of approximately 500 million cubic feet per day, equivalent to roughly 2.8 million tonnes of LNG annually. TotalEnergies will market half of this output, about 1.4 million tonnes of LNG per year. This timeline supports TotalEnergies’ ambition to grow its global LNG portfolio to 60 million tonnes per annum by 2030, reinforcing its position as the world’s third largest LNG player.

While specific development costs are not disclosed, the 2028 start-up aligns with typical deep-water project schedules in the region. The fast-track development is enabled by leveraging existing Egyptian infrastructure, which also lowers the project’s carbon intensity compared to standalone LNG developments.

Synergistic Integration with Egyptian LNG Facilities

A key aspect of the Cronos project is its integration with existing Egyptian liquefaction and export infrastructure. Gas will be piped subsea from Cypriot waters to Egypt’s Damietta LNG terminal for liquefaction before export to Europe. The project benefits from facilities linked to the Zohr field, creating significant synergies for expedited development. This approach avoids the high capital costs and extended timelines typical of standalone liquefaction infrastructure.

Utilizing existing Egyptian assets aligns with TotalEnergies’ strategic focus on low-cost, low-emission projects. This integration reduces carbon emissions and improves project economics, enhancing returns relative to greenfield LNG developments. The commercial agreements cover use of Zohr offshore facilities, gas transit through Egypt, and liquefaction at Damietta, all finalized prior to the FID.

Enhancing European Energy Security and LNG Supply Diversity

TotalEnergies’ leadership highlighted the Cronos project’s role in bolstering European energy security by diversifying LNG supply sources. Patrick Pouyanné, Chairman and CEO, stated, "this new gas route in the Mediterranean will contribute to Europe's energy security by diversifying its LNG supply sources." The project introduces LNG from a new region, decreasing reliance on existing supply corridors and providers. The FID timing coincides with increased focus on European energy independence.

The Eastern Mediterranean route offers logistical advantages with shorter transit distances to Europe compared to other LNG sources. Connecting Cypriot reserves to Egyptian export infrastructure creates a regional gas hub that may enable further developments. The project could support additional resource development in Block 6 pending appraisal results, potentially increasing LNG output beyond the initial plateau.

TotalEnergies’ Expanding Offshore Portfolio in Cyprus

The Cronos project is part of TotalEnergies’ broader presence in Cypriot offshore waters. The company operates or holds significant stakes in multiple exploration and development blocks: a 50% operating interest in Blocks 11 and 7, and 40% in Block 8. This portfolio establishes TotalEnergies as a key player in Cyprus’ emerging energy sector, with Cronos as the first production-focused project to reach FID.

This multi-block strategy reflects a long-term commitment to exploring and developing Cyprus’ hydrocarbon resources. The success of Cronos may influence exploration in adjacent blocks as operational experience grows. Details on exploration timelines or costs for other blocks are not disclosed, but additional resources in Block 6 will be appraised in upcoming campaigns.

Strategic Growth in Natural Gas and LNG Portfolio

TotalEnergies is strategically shifting towards natural gas and LNG within its energy mix, aiming to increase natural gas sales to nearly 50% by 2030. This aligns with industry trends recognizing natural gas as a transition fuel and growing LNG demand globally. Cronos contributes approximately 1.4 million tonnes of LNG annually to TotalEnergies’ marketing portfolio, supporting the 60 million tonnes per annum target.

As the world’s third largest LNG player, TotalEnergies manages a global portfolio of 44 million tonnes in 2025, with interests in liquefaction plants worldwide. The company’s integrated LNG value chain includes production, transportation, regasification capacity exceeding 20 million tonnes per annum in Europe, trading, and bunkering services. Cronos enhances this integrated position, particularly within European supply routes, while supporting carbon and methane emissions reduction goals through low-carbon infrastructure utilization.

Completion of Commercial Agreements and Contractual Framework

All principal commercial and contractual agreements necessary for Cronos’ development were finalized before the FID approval. These agreements cover access to Zohr offshore facilities, gas transit through Egypt, liquefaction at Damietta, and LNG sales arrangements. The Host Government Agreement signed in February 2025 defines the regulatory and fiscal framework.

Securing these contracts ahead of major capital expenditure reduces execution risk and regulatory uncertainty. While specific commercial terms and pricing details remain undisclosed, the completion of these agreements is a standard prerequisite for major energy companies before committing to FID on large-scale projects.

Prospects for Additional Resource Development in Block 6

The Cronos project may represent an initial phase of resource development in Block 6, with potential for future expansion. TotalEnergies and Eni indicated that upcoming appraisal campaigns will evaluate additional resources in the block. This suggests prospects for incremental LNG production beyond the 2.8 million tonnes per annum plateau from Cronos.

Future development depends on appraisal outcomes and favorable market conditions. No specific details on the size or location of these resources or timelines for appraisal and development decisions were provided. The phased approach allows deferral of capital commitments until uncertainties are clarified and market conditions validated.

Context: Deep-Water Development and Economic Efficiency

The Cronos project exemplifies advanced deep-water gas development in the Eastern Mediterranean, a region with growing exploration activity. Situated 185 kilometres offshore Cyprus, the field employs four subsea wells and long-distance export pipelines, balancing production capacity with capital and operational efficiency. Challenges include extended subsea infrastructure and marine environmental factors.

Leveraging existing Egyptian liquefaction infrastructure avoids costly standalone LNG facilities, improving project economics and reducing risk. This synergy-driven approach is increasingly common in LNG development globally. The fast-track timeline positions Cronos to supply European markets by 2028, supporting TotalEnergies’ growth and European energy security goals.
