Isabel Dos Santos
Isabel Dos Santos was appointed as chairwoman of Sonangol in June 2016 by her father, President dos Santos. He claimed it was to "ensure transparency and apply global corporate-governance standards", but many accused him of nepotism.
Her monthly salary was set at over $50,000, and she was paid exorbitant renumerations, costing Sonangol over $13 million in 14 months between 2016 and 2017. She demanded the Ministry of Finance inject $3 billion into the company, claiming it was necessary to rescue Sonangol from bankruptcy.
Isabel and her inner circle's salaries were described as "exorbidant renumerations", costing Sonangol over $13 million in 14 months between 2016 and 2017. Isabel was dismissed as chairwoman in November 2017, along with the entire board of directors under her.
She transferred $38 million of the company's funds to the Dubai-based company Ironsea (later renamed Matter), which was created by herself and her friend earlier that year. Ironsea/Matter charged Sonangol more than $130 million.
Isabel fled to Dubai to avoid arrest in Angola, and in 2022, Interpol issued a red notice towards her. She is accused of crimes including abuse of power, abuse of trust, embezzlement, forgery of documents, influence peddling, money laundering, and tax fraud.

Expansion and Development
Sonangol has been expanding its operations and services over the years. The company created subsidiaries to meet its growing needs, such as telecommunications services, retail network support, trucking, shipping, data management, scientific, engineering, seismic, and others.
Sonangol's international presence began in 1983 with the opening of its first international subsidiary, Sonangol Limited, in London. This marked the company's entry into the global market.
In 2013, Sonangol made significant deals, including a 10% stake in Marathon Oil's offshore Angolan oilfield and the acquisition of exploration rights to five onshore oil blocks in Angola.
Here are some key milestones in Sonangol's expansion and development:
- 1983: Sonangol Limited established in London
- 1992: Sonangol P & P founded as a prospection and production subsidiary
- 1999: Sonangol U.E.E. became Sonangol E.P.
- 2013: Acquired exploration rights to five onshore oil blocks in Angola
- 2023: Awarded a contract to China National Chemical Engineering Co. Ltd. (CNCEC) for EPC on the Lobito refinery
Sonangol's ongoing development projects, such as the Lobito refinery, demonstrate the company's commitment to growth and expansion.
Ongoing Lobito Development
The Lobito refinery project has seen significant developments in recent years. Sonangol has confirmed renewed activities on the project, including updating an earlier-executed FEED study for the refinery.
The FEED update works included preparing technical deliverables, defining the proposed refinery's 3D model, and preparing the project's early-FEED book. Sonangol also prepared an official preliminary project cost estimate and an invitation-to-bid package for a main EPC contractor.
Sonangol began unidentified structural works at the proposed refinery's site during 2022. The company also signed contracts with OECI SA and Dar Al-Handasah Consultants Shair and Partners Holdings Ltd. for preliminary EPC works.
In June 2023, Sonangol awarded a formal contract to China National Chemical Engineering Co. Ltd. (CNCEC) for delivery of EPC on the refinery. This contract is expected to take 40 months to complete from the start of construction.
As of February 2023, physical execution works on the Lobito refinery had reached 2%. Sonangol is also in the process of consolidating technical studies for possible integration of petrochemicals at the project.

Sonadiets (Until 2022)
Sonadiets Limitada and Sonadiets Services Limitada were Luanda-based joint ventures between Sonangol and international energy firm Dietsmann.
They provided operational and maintenance support for the petrochemical industry, as well as workforce training. Their clients included Sonangol subsidiaries, as well as Total, ExxonMobil, and Eni.
Sonangol sold its 30% stake in Sonadiets Limitada and 51% in Sonadiets Services in 2022.
Privatization and Restructuring
In February 2019, the Angolan government launched its Propriv privatization program, creating the National Oil, Gas and Biofuel Agency (ANPG) to regulate and promote the petroleum industry.
ANPG took over regulation and promotion from Sonangol, and was given the power to supervise Sonangol, becoming the new national concessionaire.
In May 2019, Carlos e Oliveira was replaced by Sebastião Gaspar Martins as head of the company.
Sonangol will refocus on its core business: the petroleum industry, and will sell its peripheral businesses such as aviation, banking, hotels, and real estate, many of which were built during the regime of the dos Santos family.
By 2027, Sonangol will undergo a partial privatization, making 30% of its shares available for purchase.
Here are some of the businesses that Sonangol is selling:
- Centro de Convenções de Talatona (CCTA) convention center
- Hotel da Base do Kwanda
- Hotel de Convenções de Talatona (HCTA) five-star hotel
- Hotel Florença three-star hotel in Luanda
- Hotel Rio Mar hotel in Benguela
- Hotel Suíte Maianga hotel in Luanda
Privatization and Streamlining
In February 2019, the Angolan government launched the Propriv privatization program, which aimed to transform the state-owned oil company Sonangol.
The program created the National Oil, Gas and Biofuel Agency (ANPG) to regulate and promote the Angolan petroleum industry, taking over from Sonangol.
ANPG now controls who wins licenses to explore for petroleum and awards contracts for production.
Carlos e Oliveira was sacked as head of Sonangol in May 2019 and replaced by Sebastião Gaspar Martins.
The Ministry of Finance began conducting a pruning of Sonangol's other functions in April 2020, including the sale of peripheral businesses such as aviation, banking, hotels, and real estate ventures.
Sonangol will refocus on its core business: the petroleum industry.
A partial privatization of Sonangol is planned, with 30% of its shares available for purchase by 2027.

The reforms aim to transform Sonangol from a regulating body and oil producer into a corporate entity overseen by a separate state entity.
Here are some of the hotels and other businesses that will be sold:
- Centro de Convenções de Talatona (CCTA) convention center
- Hotel da Base do Kwanda
- Hotel de Convenções de Talatona (HCTA) five-star hotel
- Hotel Florença three-star hotel in Luanda
- Hotel Rio Mar hotel in Benguela

Privatization and Restructuring
Sonangol, the Angolan state-owned oil company, has been involved in a series of privatization and restructuring efforts that have led to significant financial losses for the state.
Between 2005 and 2008, Didier Keller, the CEO of SBM Offshore, paid key Sonangol officials a total of US$ 6.8 million in bribes.
The construction of the Centro de Convenções de Talatona (CCTA), a convention center in Angola, was financed solely by Sonangol but resulted in a 30% stake being held by private companies, including Simaroco and Oil International Supply Services S.A.
A ten-year, US$ 12 million contract for the management of the Hotel de Convenções de Talatona (HCTA) was awarded to Dream's Leisure, a company created 13 days prior to the contract, owned by Manuel Vicente, then chairman of the board of directors of Sonangol.
Worth a look: US Airways
The contract stipulated that Sonangol would compensate Dream's Leisure for any net losses incurred through management of the hotel, which encouraged Dream's Leisure to inflate costs and declare losses.
In July 2019, President Lourenço canceled the contract, returning control of the Talatona hotel to the state.
Between 2007 and 2010, the government of Angola spent or transferred US$32 billion from government funds linked to Sonangol without proper documentation in the budget.
The International Monetary Fund (IMF) was assured that most of the US$32 billion was being used for "legitimate government reasons" and considered to be "found".
