Group Sonangol () is a state-owned enterprise that has traditionally overseen the extraction and production of petroleum and natural gas within Angola. The organization consisted of Sonangol E.P. () along with various subsidiaries, which mainly supported Sonangol E.P. as well as other corporate and private clients. In 2023, Sonangol's daily oil output reached 202,000 barrels, resulting in revenues amounting to US$10.9 billion.

Establishment

Following Angola’s independence from Portugal after the Carnation Revolution in 1976, the company ANGOL (Sociedade de Lubrificantes e Combustíveis SARL), initially created in 1953 as a subsidiary of the Portuguese firm SACOR, was nationalized and divided into two entities: Sonangol U.E.E. and Direcção Nacional de Petróleos. Directive 52/76 formally designated Sonangol as a government-owned corporation responsible for managing Angola’s vast petroleum industry. Utilizing infrastructure previously held by Texaco, Total, Shell, and Mobil, Sonangol obtained technical assistance from Algeria’s Sonatrach and Italy’s Eni.

Growth and Diversification

As Sonangol expanded, it created several subsidiaries to deliver critical services including telecommunications, retail support networks, logistics via trucking and shipping, data administration, as well as scientific research, engineering, and seismic exploration activities. Over time, both the parent company and its affiliates broadened their operational scope.

In 1983, Sonangol inaugurated its first overseas branch, Sonangol Limited, based in London. The year 1992 saw the formation of Sonangol P & P, focusing on exploration and production. By 1999, Sonangol U.E.E. transitioned to the name Sonangol E.P.

In September 2013, Marathon Oil agreed to divest a 10% interest in its offshore Angolan oil field to Sonangol for $590 million. Later that year, Sonangol acquired exploration rights over five onshore oil blocks within Angola, positioning itself strategically for upcoming development projects.

Didier Keller Bribery Scandal

A Swiss court ruling in 2020 determined that Didier Kelley, who served as CEO of SBM Offshore between 2005 and 2008, disbursed US$6.8 million in bribes to officials at Sonangol. Kelley was subsequently fined more than US$500,000. At that time, Manuel Vicente was chairman of Sonangol’s board and also held the position of Vice President of Angola under President José Eduardo dos Santos. Although Vicente was not formally charged with accepting bribes, Swiss investigators believed he had knowledge of the illicit payments.

Dream's Leisure Controversy

From 2006 onwards, Sonangol funded the construction of the Centro de Convenções de Talatona (CCTA), a convention center inaugurated in December 2009 by President dos Santos. The complex included the five-star Hotel de Convenções de Talatona (HCTA) and represented an investment exceeding US$200 million by Sonangol. Despite being the sole financier, Sonangol retained only a 30% ownership share; majority control rested with Simaroco alongside Oil International Supply Services S.A. (OISS) and a Chinese investor. Simaroco was established in 2005 by José Carlos de Castro Paiva, who was then chairman of Sonangol Limited and acted as Sonangol’s representative on the board of the Banco Africano de Investimentos. OISS had partial ownership by Alberto Cardoso Severino Pereira, former financial director at Sonangol, and Domingos de Assunção de Sousa de Lima Viegas, a lawyer employed by Sonangol and member of BAI’s audit committee. This structure effectively transferred millions in public assets into private ownership.

A decade-long contract worth US$12 million for managing the HCTA was granted to Dream's Leisure—a company established only thirteen days prior to receiving this agreement. Ownership of Dream's Leisure included Manuel Vicente (then chairman of Sonangol’s board), Francisco Maria de Lemos (Sonangol’s financial director), and Orlando Veloso (engineering director). The contract obligated Sonangol to absorb any operational losses incurred by Dream's Leisure while managing the hotel and prohibited Sonangol from assigning third-party rights without Dream's Leisure’s consent. Legal analysts criticized this arrangement as fostering inflated expenses and losses designed to facilitate misappropriation of state assets.

Exem Energy and Sindika Dokolo

In 2006, Exem Energy BV acquired a 6% interest in the Portuguese energy firm Galp Energia, valued at approximately US$750 million. This purchase was financed by an US$11 million loan from Sonangol. The ownership was structured through holding entities Amorim Energia—which controlled 33.45% of Galp—and Esperaza, which held 45% of Amorim. Exem Energy BV was 40% owned and effectively managed by Sindika Dokolo, who is married to President dos Santos's daughter, Isabel dos Santos.

A Dutch arbitration panel in Amsterdam, in 2020, deemed the acquisition "marred by illegality," concluding it was executed to secure exceptional financial benefits at the expense of Sonangol and Angola. The tribunal ordered a freeze on Exem’s assets and mandated the restitution of the shares to Sonangol, affirming the corrupt nature of the deal. This ruling followed Sonangol’s legal efforts to reclaim assets tied to Isabel dos Santos’s business network.

Unaccounted-for billions

In December 2011, Human Rights Watch urged the Angolan government to clarify the disappearance of US$32 billion connected to Sonangol. An IMF report from that same period highlighted that funds between 2007 and 2010 were allocated or transferred without proper budgetary documentation. Subsequently, the IMF was reassured that the majority of the $32 billion had been utilized for "legitimate government purposes" and regarded as "accounted for."

Isabel dos Santos

In June 2016, President dos Santos overhauled Sonangol’s entire board, appointing his daughter Isabel as chairwoman with the stated goal of "ensuring transparency and implementing international corporate governance standards." This decision provoked allegations of corruption and nepotism. One year later, reports surfaced that Isabel sought a US$3 billion bailout from the Ministry of Finance to prevent Sonangol’s collapse; however, this request was denied.

Isabel and her management team received salaries described as "excessive," costing Sonangol more than US$13 million over a 14-month span (2016–2017), with her monthly compensation surpassing US$50,000.

On November 15, 2017, Angola’s newly elected President João Lourenço removed Isabel and her board members, appointing Carlos Saturnino Guerra Sousa e Oliveira as chairman. An internal audit exposed that following her dismissal, Isabel transferred US$38 million in company funds to Ironsea (later renamed Matter), a Dubai-based company she co-founded. Ironsea/Matter invoiced Sonangol for over US$130 million.

To evade arrest, Isabel fled to Dubai; in 2022, Interpol issued a red notice for her apprehension. She faces multiple charges including abuse of power, embezzlement, forgery, money laundering, and tax fraud. In June 2023, she was found guilty of embezzling €52.6 million from Sonangol.

Privatization and streamlining

In February 2019, the Angolan government initiated its privatization initiative known as Propriv and created the National Oil, Gas and Biofuel Agency (ANPG) to oversee and promote activities in the petroleum sector, transferring these responsibilities from Sonangol. Currently, ANPG supervises Sonangol and acts as the national concessionaire, managing licensing and contract awards related to oil exploration and production.

In May 2019, Sebastião Gaspar Martins succeeded Carlos e Oliveira as head of Sonangol. Later in July 2019, President Lourenço terminated Dream's Leisure contract, restoring state control over the Talatona hotel.

By April 2020, the Ministry of Finance started divesting Sonangol’s non-core holdings—including interests in aviation, banking, hospitality, and real estate—many of which were established during the dos Santos administration. The company refocused on its primary oil operations and launched a partial privatization plan targeting a sale of 30% of its shares by 2027. These reforms seek to separate Sonangol’s regulatory duties from its production activities by converting it into a corporate entity governed by an independent state agency while preserving majority government ownership.

It maintains a worldwide presence through a broad network of subsidiaries and partnerships spanning upstream, midstream, and downstream segments of the petroleum industry, as well as ventures outside the oil sector across Africa, North America, Latin America, Europe, and Asia.
