Oil continues to occupy a complicated but essential place in Colombia’s economy. The country is an established producer with mature fields, extensive pipeline infrastructure, two major refineries and a national oil company that operates across the entire petroleum value chain. Crude exports also provide foreign currency and government revenue that cannot be replaced quickly.
At the same time, Colombia has a relatively short reserve horizon. Production depends heavily on extracting more oil from existing fields, developing discoveries made under current contracts and maintaining infrastructure across difficult terrain. The government’s decision to stop awarding new exploration contracts has added a new strategic question: how long can Colombia sustain production while it attempts to reduce its dependence on fossil fuels?
The Llanos Basin remains the centre of Colombian oil production
Colombia’s oil industry is spread across several sedimentary basins, but the Llanos Orientales region has become the country’s most important production centre. The basin extends across the eastern plains and includes major operations in the departments of Meta, Casanare and Arauca.
Fields such as Rubiales, Castilla, Chichimene and Caño Sur have helped establish Meta as Colombia’s leading oil-producing department. Ecopetrol and private operators continue to invest in drilling, water management, enhanced recovery and surface facilities in this region. These investments are important because many Colombian fields are mature and require continuous work simply to maintain output.
Colombian production is dominated by medium and heavy crude grades. Heavy oil can remain commercially valuable, but it creates additional transportation and refining requirements. Some crude must be blended with lighter products before it can move efficiently through pipelines. This raises operating costs and makes dependable transport infrastructure especially important.
National crude production averaged approximately 773,000 barrels per day in 2024. Production during the first months of 2026 was lower, at roughly 741,000 barrels per day. The decline does not represent the disappearance of Colombia’s petroleum industry, but it shows how natural field depletion, operational interruptions and limited additions from large new developments can gradually reduce national output.
Ecopetrol remains the central company in the sector. The Colombian state holds a controlling interest, while the company also has private shareholders. Through Ecopetrol and its subsidiaries, the country participates in exploration, production, pipelines, refining, petrochemicals, fuel distribution and other energy businesses.
Private and international companies also operate under contracts administered by the National Hydrocarbons Agency. Their role is particularly important in smaller fields and in areas where specialized production techniques, exploration experience or additional capital are required.
Pipelines connect inland fields with refineries and export terminals
Colombia’s geography makes oil transportation a major part of the industry. Much of the crude is produced east of the Andes, while the principal refineries, population centres and export terminals are located farther west or along the Caribbean coast.
The Ocensa pipeline is one of the most important parts of this system. It moves crude from the Llanos region across the country to the Caribbean export terminal at Coveñas. The Caño Limón–Coveñas pipeline connects fields in Arauca with the same coastal area, while additional systems serve Meta, Casanare, the Magdalena Valley and other producing regions.
These pipelines allow Colombia to export crude even though most production occurs far inland. They also expose the industry to landslides, flooding, illegal connections, security incidents and local blockades. Interruptions can force producers to reduce output when storage capacity fills or transport routes become unavailable.
Coveñas is the country’s principal crude-export terminal. Colombian oil is sold to several international markets, including refineries in the United States and Asia that can process heavier crude grades. Export destinations change with refinery demand, freight costs, price discounts and competition from similar barrels produced elsewhere in the Americas.
The domestic refining industry is centred on the Barrancabermeja and Cartagena refineries. Barrancabermeja developed alongside Colombia’s early petroleum industry and remains a major inland refining and petrochemical complex. The modernized Cartagena refinery gives the country a large processing centre on the Caribbean coast, close to maritime import and export routes.
Together, the two refineries convert domestic and imported crude into gasoline, diesel, jet fuel, liquefied petroleum gas and industrial products. Their operation reduces Colombia’s dependence on finished-fuel imports, although the country still imports petroleum products when domestic output, refinery availability or fuel quality requirements create a supply gap.
A short reserve horizon shapes the national oil debate
Colombia reported approximately 2.04 billion barrels of proved oil reserves at the end of 2024. The country replaced about 105% of the oil produced during that year, allowing reserves to increase slightly rather than decline.
The reserve-to-production ratio nevertheless remained only 7.2 years. This figure does not mean Colombia will suddenly run out of oil after seven years. Companies regularly convert resources into proved reserves by drilling wells, expanding fields, improving recovery rates and completing technical studies. However, the ratio shows that Colombia has less room for long periods of weak exploration than producers with several decades of proved reserves.
Recent reserve additions have come largely from improved management of existing fields and previously discovered resources. Operators have extended field boundaries, increased recovery from known reservoirs and moved contingent resources into commercial categories. This approach can maintain production, but it may not provide the same long-term security as repeated discoveries of large new fields.
No new petroleum exploration contracts have been signed since 2022. Existing contracts remain valid, and companies can continue drilling, evaluating discoveries and developing commercial projects within those areas. The policy therefore limits the expansion of the exploration portfolio without immediately ending upstream activity.
Supporters of this direction view it as part of Colombia’s transition toward a more diversified and lower-emission economy. They argue that public policy should encourage renewable electricity, cleaner transport, energy efficiency and new export industries rather than deepen long-term dependence on petroleum.
The oil industry and producing regions focus on a different risk. A rapid production decline could reduce export earnings, royalties, tax revenue and funding for regional governments before replacement industries are fully developed. Colombia may also need to import more crude or refined fuel if domestic production falls faster than national demand.
Oil revenue still supports the wider Colombian economy
Petroleum remains one of Colombia’s most important export industries. Its influence extends beyond the value of crude shipments. Oil companies purchase transportation, engineering, construction, maintenance, security and professional services. Producing regions receive royalties, while the national government collects taxes and dividends from Ecopetrol.
This economic role makes the petroleum transition difficult to manage. Colombia can reduce its long-term dependence on oil, but it must also consider the public finances and employment supported by the existing industry. A disorderly decline would affect government revenue and the trade balance as well as oil-producing companies.
Oil also remains central to domestic energy consumption. Transport continues to depend heavily on gasoline, diesel and aviation fuel. Electric vehicles, public transport investment and alternative fuels may reduce this demand over time, but replacing the national vehicle fleet and supporting infrastructure will take many years.
Ecopetrol has responded by developing a broader energy portfolio. The group remains focused on hydrocarbons while investing in renewable electricity, power transmission, low-carbon fuels, hydrogen and emissions reduction. This allows the company to use petroleum income and technical capability to enter businesses that may become more important as the energy system changes.
Colombia’s oil future depends on managing decline rather than ending production suddenly
Colombia is likely to remain an oil producer and exporter for years, but the industry’s future will depend increasingly on assets that are already known. Development drilling, enhanced recovery and reliable pipelines will be needed to slow natural decline in the Llanos and other mature basins.
The central issue is not whether petroleum disappears immediately. It is whether reserve replacement and investment can remain strong enough to prevent a sharp fall in production while the economy develops new sources of exports and public revenue.
Existing discoveries and contracts provide Colombia with options, but the short reserve horizon leaves limited room for delays. The country’s energy transition will therefore be judged partly by its ability to reduce structural dependence on oil without creating a premature supply, fiscal or trade imbalance.
