Eni S.p.A. (originally Ente Nazionale Idrocarburi, “National Hydrocarbons Board”) is an Italian multinational energy company headquartered in Rome. The company is one of the world’s “supermajor” oil and gas producers—ranked alongside ExxonMobil, Shell, BP, Chevron, and TotalEnergies—with operations across the entire energy value chain: exploration and production, refining and marketing, gas and power, chemicals, and increasingly renewable energy and mobility solutions.
The Italian government established Eni by law on February 10, 1953, consolidating existing state energy assets including Agip (Azienda Generale Italiana Petroli), which had been founded in 1926 under Mussolini’s fascist government. The driving force behind Eni’s creation and early success was Enrico Mattei, a former resistance fighter appointed chairman in 1953. Mattei transformed the company from a near-bankrupt entity he was supposed to liquidate into a powerful state oil company that challenged the dominance of the “Seven Sisters”—the Anglo-American oil cartel that controlled the global petroleum industry.
Mattei pioneered the “Mattei formula,” offering oil-producing nations a 75-25 profit split (versus the standard 50-50), which secured crucial concessions across North Africa and the Middle East. His mysterious death in a 1962 plane crash—later confirmed as assassination—remains one of Italy’s most enduring political mysteries. Under successive leadership, Eni expanded through the 1973 oil crisis, built major pipeline networks including the Trans-Mediterranean and Blue Stream, and was privatized beginning in 1992 (listed on the Milan and New York exchanges in 1995). Today, the Italian government retains a 30.5% “golden share,” with CEO Claudio Descalzi leading the company since 2014 through a strategy balancing upstream oil and gas operations with investments in renewables and decarbonization.
Eni History
1926–1952
Agip Origins
Agip (Azienda Generale Italiana Petroli) is established in 1926 under Italy’s fascist government to explore for oil and reduce dependence on foreign petroleum. After World War II, Enrico Mattei—a former partisan commander—is appointed commissioner of Agip for northern Italy in 1945, ostensibly to liquidate the company. Instead, Mattei directs expanded exploration in the Po River valley, discovering major natural gas reserves that establish the case for state-led energy development. In 1952, Eni adopts its famous six-legged dog logo (the “cane a sei zampe”), symbolizing the four wheels of a car plus two legs of its driver.
1953–1962
Mattei Era
On February 10, 1953, the Italian parliament establishes Eni (Ente Nazionale Idrocarburi) as the national hydrocarbons company, with Enrico Mattei as chairman. In 1954, Eni secures exploration rights in North Africa through an agreement with Egypt’s Nasser government, pioneering joint ventures that give producing countries an active role. In 1957, Mattei introduces the “Mattei formula”—offering Iran a 75-25 profit split versus the industry-standard 50-50—directly challenging the “Seven Sisters” oil cartel. In 1960, Eni signs a groundbreaking agreement with the Soviet Union for crude imports at favorable prices. Mattei dies on October 27, 1962, when his private jet crashes near Bascapè; initially ruled an accident, his death is later confirmed as murder.
1963–1973
Post-Mattei Expansion
Following Mattei’s death, Eni decentralizes management and continues expansion. In 1963, Eni acquires a majority stake in Italgas (Italian gas distribution). Joint ventures with foreign companies secure crude supplies from Egypt, Iran, Libya, and Tunisia. In 1972, Eni makes two major oil discoveries in the British North Sea. By the early 1970s, Eni operates one of the largest international petroleum distribution networks, with Agip service stations, motels, and restaurants across Europe and Africa.
1973–1989
Oil Crisis & Pipeline Infrastructure
The October 1973 OPEC oil embargo following the Yom Kippur War pushes Eni to diversify supply sources. In 1974, Eni signs agreements with Libya, Egypt, Nigeria, and Tunisia. The company builds extensive natural gas pipeline infrastructure across Europe and the Mediterranean, including the Trans-Mediterranean Pipeline connecting Algeria to Sicily via Tunisia (inaugurated 1983). Eni also develops the Boùri oilfield, the largest in the central Mediterranean, through an agreement with Libya.
1992–1998
Privatization
In 1992, Eni becomes a joint-stock company (S.p.A.) by law decree. The company lists on the Milan and New York Stock Exchanges in 1995. Between 1995 and 1998, Eni conducts four successful share offerings, selling 70% of its capital to private shareholders while the Italian government retains a 30% “golden share.” The 1998 oil price collapse triggers industry consolidation; Eni responds with mergers, acquisitions, and new exploration.
2000–2012
Global Megaprojects
In 2000, Eni begins developing the Kashagan oilfield in Kazakhstan’s Caspian Sea—one of the world’s largest offshore oil discoveries. In 2005, the Blue Stream pipeline (a joint venture with Russia’s Gazprom) begins delivering Russian gas to Turkey beneath the Black Sea. In 2007, Eni signs a feasibility study with Gazprom for the South Stream pipeline to transport Russian gas to Europe. In 2010, Eni achieves production milestones at Iraq’s Zubair oilfield. Between 2011 and 2012, major natural gas discoveries in Mozambique’s Area 4 (Mamba South, Mamba North, Coral 1) establish one of the largest gas finds in the world.
2014–2019
Descalzi Era Begins
Claudio Descalzi becomes CEO in May 2014. In 2015, Eni discovers Zohr, one of the largest natural gas fields ever found in the Mediterranean, offshore Egypt. In 2016, Descalzi launches “Progetto Italia” for zero-emission energy production. The company opens biorefineries (Venice 2014, Gela 2019) converting traditional refineries to biofuel production. In 2018, Eni participates in MIT’s magnetic confinement fusion project with Commonwealth Fusion Systems. The company divests Eastern European refining assets to focus on higher-margin operations.
2020–2025
Energy Transition & Satellite Model
In 2021, Eni launches a new strategy combining traditional oil and gas with decarbonization, creating Plenitude (renewables and retail energy) and Enilive (mobility and biofuels) as separate business units. The Coral Sul FLNG project in Mozambique delivers first cargo in 2022. In 2023, Eni’s Baleine Phase 1 offshore Côte d’Ivoire begins production—billed as the world’s first net-zero upstream project for Scope 1 and 2 emissions. Baleine Phase 2 starts production in December 2024. In 2025, Eni launches a carbon capture and storage (CCS) satellite company, with BlackRock’s GIP taking a stake. Revenue reaches €91.2 billion (2024), with production of approximately 1.7 million barrels of oil equivalent per day.
Founder
Enrico Mattei (1906–1962)
Enrico Mattei was born on April 29, 1906, in Acqualagna, Marche, Italy. After working as an industrial manager in the private sector, he became a commander in the Italian resistance during World War II, organizing an anti-fascist force of 82,000 in northern Italy. His wartime service led to prominence in the Christian Democratic Party after liberation.
In 1945, Mattei was appointed commissioner of Agip for northern Italy with instructions to liquidate the near-bankrupt state oil company. Instead, recognizing the potential of domestic hydrocarbon reserves, he directed expanded exploration in the Po River valley, discovering major natural gas deposits that saved Italy millions of lire on imports. These successes led the Italian parliament to establish Eni in February 1953, with Mattei as chairman.
Mattei transformed Eni from a national utility into a global oil company that challenged the dominance of the “Seven Sisters”—the Anglo-American oil cartel (predecessors of ExxonMobil, Chevron, Shell, and BP). He coined the derisive term “Seven Sisters” himself. His “Mattei formula” (75-25 profit splits favoring producing nations) secured crucial concessions in Egypt, Iran, and other countries, making Eni a model for national oil companies worldwide.
On October 27, 1962, Mattei’s private jet crashed near Bascapè while flying from Sicily to Milan. Initially ruled an accident, investigations decades later confirmed the crash was an assassination—likely involving the Sicilian Mafia and foreign intelligence services protecting established oil interests. His death inspired the 1972 film “Il Caso Mattei” by Francesco Rosi. Today, Eni’s headquarters sits on Piazzale Enrico Mattei in Rome.

Eni Revenue
Eni operates through multiple segments: Exploration & Production (the largest contributor), Global Gas & LNG Portfolio, Refining & Chemicals, Enilive (mobility and biofuels), and Plenitude (renewables and retail energy). Revenue peaked at €132.5 billion in 2022 due to the energy price surge following Russia’s invasion of Ukraine, then declined as prices normalized.
Note: 2022 revenue spike reflects post-Ukraine energy price surge. The Italian government holds a 30.5% “golden share” in Eni (1.99% Ministry of Economy and Finance, 28.5% Cassa Depositi e Prestiti).
Eni Competitors
Eni competes with the other “supermajor” oil and gas companies—integrated multinationals that operate across exploration, production, refining, and marketing. It is typically considered the smallest of the supermajors by revenue but has differentiated through exploration success, particularly in Africa and the Mediterranean.

FAQs
What does Eni stand for?
Eni originally stood for “Ente Nazionale Idrocarburi” (National Hydrocarbons Board), the Italian state agency established by law on February 10, 1953. When Eni was privatized in the 1990s, the acronym ceased to have legal meaning, but the company retained the name. Today, “Eni” is simply used as a brand name and is no longer considered an acronym.
Who was Enrico Mattei and how did he die?
Enrico Mattei (1906–1962) was the founding chairman of Eni who transformed the company from a near-bankrupt state entity into a global oil power that challenged the “Seven Sisters” oil cartel. He pioneered the “Mattei formula”—offering producing nations a 75-25 profit split—which secured crucial concessions in Egypt, Iran, and other countries. Mattei died on October 27, 1962, when his private jet crashed near Bascapè, Italy. Initially ruled an accident, later investigations confirmed the crash was an assassination, likely involving organized crime and foreign interests threatened by Mattei’s challenge to established oil industry power structures.
Is Eni state-owned?
Eni is partially state-owned. The Italian government holds a 30.5% “golden share”—approximately 1.99% through the Ministry of Economy and Finance and 28.5% through Cassa Depositi e Prestiti (CDP), Italy’s state investment bank. The remaining approximately 70% is publicly traded on the Milan Stock Exchange (BIT: ENI) and New York Stock Exchange (NYSE: E). Eni was fully state-owned from its founding in 1953 until privatization began in 1992, with the company listing publicly in 1995.
What is the six-legged dog logo?
Eni’s iconic logo—the “cane a sei zampe” (six-legged dog)—was designed in 1952 by Luigi Broggini and selected through a public competition. The imaginary animal symbolizes the combination of a car’s four wheels plus the two legs of its driver, representing the link between automobiles and petroleum products. The six-legged dog became one of Italy’s most recognized corporate symbols, appearing on Agip gas stations throughout Europe and Africa. While Eni has modernized its brand in recent years, the six-legged dog remains associated with the company’s service stations.
What is the difference between Eni and Agip?
Agip (Azienda Generale Italiana Petroli) was the original Italian state oil company, founded in 1926 under the fascist government. When Eni was established in 1953, Agip became a subsidiary focused on exploration, production, refining, and fuel retail marketing. The Agip brand was primarily used for service stations and lubricants, while Eni served as the parent holding company. Following Eni’s reorganization in the 2000s, the company began transitioning service stations from the Agip brand to the Eni brand. Today, Agip descendants form Eni’s exploration/production and refining/marketing divisions, though the Agip brand is being phased out in favor of the unified Eni identity.
