South Africa has one of Africa’s largest fuel markets, but it produces very little conventional crude oil. Its petroleum economy has traditionally depended on imported crude processed in local refineries, imported finished fuels and synthetic liquids made from coal. That balance has changed sharply as several refineries have closed or stopped processing crude.
The country now imports around three-quarters of the liquid fuel it needs. This dependence is not only a trade issue. Petrol, diesel, jet fuel and other petroleum products support road freight, mining, farming, aviation and daily transport across a large territory. A disruption at a port, terminal, pipeline or remaining refinery can therefore affect much more than service stations.
South Africa imported about 138,000 barrels per day of crude oil and condensate in 2023, with Nigeria, Saudi Arabia and the United States among the main sources. However, crude-import figures no longer describe the full market because the country increasingly buys refined products directly. The central question is no longer how much crude South Africa can process, but how reliably it can secure and distribute finished fuel.
Durban’s Refinery Closures Changed the Supply Map
For decades, Durban was the centre of South African refining. The city combined marine import facilities, crude storage, refineries and pipeline links to the inland economic region around Johannesburg. The shutdown of the Engen refinery in 2020 and the suspension of refining at SAPREF in 2022 removed two of the country’s largest crude-processing plants.
SAPREF had capacity of roughly 180,000 barrels per day before it stopped refining. Flood damage in KwaZulu-Natal added to the challenge of returning the site to operation. Its current role is centred on the Island View terminal, which receives imported petroleum products. Infrastructure once designed to bring in crude for domestic processing is increasingly being used to import finished fuels.
The loss of Durban refining capacity has increased dependence on foreign refineries and international product markets. When regional or global supply is tight, South African buyers compete for cargoes of diesel, petrol and jet fuel that meet local specifications. Importing finished fuel can be rational when domestic plants are old or expensive to upgrade, but it increases exposure to shipping delays, port congestion, currency movements and limited strategic stocks.
Astron and Natref Carry a Smaller Refining Base
Two conventional crude refineries remain central to domestic supply. Astron Energy operates a refinery near Cape Town with capacity of about 100,000 barrels per day. The facility returned to operation in 2023 after a long shutdown following a 2020 explosion.
Astron is investing up to R6 billion to meet South Africa’s Clean Fuels II standards. These rules are scheduled to require petrol and diesel with sulphur levels of 10 parts per million from July 2027. The investment demonstrates that at least one major operator sees value in retaining and upgrading local refining.
Natref, located at Sasolburg, is the country’s only inland crude refinery. It can process about 108,500 barrels per day and is operated by Sasol, which holds the majority interest. Crude reaches the plant through infrastructure connected to the Durban import system. Its location near South Africa’s main economic market is valuable, but inland refining depends heavily on reliable pipelines and electricity.
The ownership of Natref’s minority stake is unsettled. Prax Group acquired the interest previously held by TotalEnergies, but the stake returned to the market after Prax entered administration in 2025. In 2026, Trafigura and two South African companies were reported to be among the bidders. The outcome matters because Natref needs a financially strong partner able to support maintenance, cleaner-fuel investment and long-term crude supply.
Sasol’s Synthetic Fuels Provide a Strategic Buffer
South Africa’s fuel system is unusual because Sasol produces liquid fuels from coal at Secunda. The coal-to-liquids complex supplies petrol, diesel, jet-fuel components and chemical feedstocks without using conventional crude oil. It provides a domestic buffer and supports fuel availability in the inland market.
Synthetic fuel does not make South Africa oil-independent. Secunda cannot meet total demand, and its production depends on large coal, water, electricity and industrial systems. It is also highly carbon-intensive. Even so, the facility remains strategically important because replacing its output would require additional imported fuel and expanded terminal, storage and pipeline capacity.
The combination of Natref and Secunda gives Sasol a major position in the national liquid-fuels market. Operational disruptions at either site can quickly increase the need for imports, making maintenance performance a national supply-security issue.
SAPREF Has Become a Test of State Petroleum Strategy
The government’s acquisition of SAPREF assets reflects concern about the loss of domestic refining. The Central Energy Fund bought the former refinery assets from BP and Shell, and they now sit within a wider effort to strengthen state participation in petroleum.
The South African National Petroleum Company began operating in May 2025 through the integration of PetroSA, iGas and the Strategic Fuel Fund. Its mandate includes petroleum assets, strategic stocks, infrastructure and participation in upstream and downstream projects. SAPREF gives the state a major coastal site, but ownership alone does not restore refining capacity.
Returning the old refinery to service would require extensive repairs, environmental work, modern fuel-quality equipment and a credible commercial plan. Government proposals have included a much larger future refinery at the site, but such an expansion would demand very large capital investment and secure crude supply. The more immediate value may lie in import terminals, storage, marine access and distribution infrastructure.
South Africa therefore faces a practical choice. It can invest heavily to rebuild domestic refining, or accept greater product imports while strengthening terminals, pipelines and strategic reserves. A mixed approach is more likely, with selective refinery upgrades combined with a larger import system.
Offshore Potential Has Not Yet Changed the Market
South Africa introduced a separate legal framework for upstream petroleum development through the Upstream Petroleum Resources Development Act of 2024. The aim is to provide clearer rules for exploration, production rights and state participation.
The country has offshore geological potential, but exploration has faced regulatory delays, environmental challenges, high costs and uncertainty over commercial discoveries. Domestic crude production remains too small to support the national market or transform refinery economics. New discoveries could reduce import dependence over time, but they are not a near-term answer to fuel supply.
For now, oil security depends much more on infrastructure than geology. Durban’s marine facilities, pipelines to the interior, Cape Town’s refinery and terminals, Saldanha Bay storage and inland distribution networks matter more to current supply than unproduced offshore prospects.
Reliability Matters More Than Self-Sufficiency
South Africa is unlikely to regain full petroleum self-sufficiency. Its market is too large, domestic crude production is too limited and much of its refining fleet requires expensive renewal. The realistic objective is a resilient balance among local refining, synthetic fuels, imports and strategic storage.
Astron’s clean-fuels investment and the future ownership of Natref will determine how much conventional refining remains viable. The handling of SAPREF will show whether the state can convert an acquired industrial site into dependable supply infrastructure. At the same time, ports, terminals and pipelines must manage a larger flow of imported products.
The country’s oil outlook rests on execution. Stable supply will require reliable plants, sufficient stocks, efficient ports, clear regulation and financially credible investment. South Africa may process less crude than it once did, but petroleum will remain essential to transport and industry. The strongest system will be the one that can absorb disruptions without leaving the economy short of fuel.
