Oil remains one of Ecuador’s most important export industries, yet the sector is no longer defined by rapid expansion. The country has substantial reserves, an established state oil company and direct access to Pacific shipping routes, but production has remained within a relatively narrow range for many years. Mature fields, limited investment, pipeline disruptions and disputes over development in the Amazon have prevented Ecuador from converting its resource base into sustained output growth.
National crude production stood at approximately 456,000 barrels per day in April 2026. EP Petroecuador supplied nearly 359,000 barrels per day, leaving private operators responsible for slightly more than one-fifth of production. This balance reflects the state’s dominant position across exploration, production, pipelines, refining and fuel distribution.
Ecuador therefore enters the next stage of its oil history with two competing priorities. The government wants additional production and investment to support public finances, while environmental rulings, Indigenous rights and the result of the Yasuní referendum are reducing the area available for development.
Ecuador’s Oil Industry Is Concentrated in the Amazon
Most Ecuadorian crude is produced in the Oriente Basin, east of the Andes. The main operating areas are located in the provinces of Sucumbíos, Orellana and Napo, where oil development has shaped local infrastructure and the national economy since large-scale exports began in the 1970s.
Ecuador held an estimated 8.27 billion barrels of proved oil reserves at the end of 2022. This is a significant resource base for a country producing less than half a million barrels per day, although the total does not mean that every barrel can be developed economically or politically. Much of the remaining resource is located in environmentally sensitive parts of the Amazon, while several established fields require continued drilling and enhanced recovery simply to offset natural decline.
Petroecuador operates many of the country’s most productive assets. These include the Sacha, Auca, Shushufindi-Libertador, Cuyabeno and Eden-Yuturi areas. In April 2026, Sacha was producing roughly 70,600 barrels per day, Shushufindi-Libertador approximately 71,300 barrels per day and Auca about 59,000 barrels per day. Their continuing importance shows why field maintenance, workovers, water management and secondary recovery are central to Ecuador’s production outlook.
Private companies provide a smaller but still important share of national output. Operators have included Andes Petroleum, PetroOriental, ENAP Sipetrol, Gran Tierra Energy, Pluspetrol and several smaller companies. Private investment is particularly valuable because the state faces competing budget demands and Petroecuador must finance activity across the entire petroleum chain.
Ecuador produces both Oriente and Napo crude. Oriente is generally the more valuable of the two export grades, while Napo is heavier and normally trades at a larger discount to international benchmarks. Crude quality affects refinery compatibility, transport arrangements and the final price received by the country.
The Yasuní Vote Changed the Direction of Ecuadorian Oil
No issue better represents the tension inside Ecuador’s oil sector than Block 43-ITT. The Ishpingo, Tambococha and Tiputini fields are located in Yasuní National Park, an area known for exceptional biodiversity and for the presence of Indigenous communities, including peoples living in voluntary isolation.
Block 43 became one of Petroecuador’s largest producing assets after commercial operations began in 2016. However, Ecuadorian voters decided in a 2023 national referendum that the oil should remain underground. The result required the government to end production and remove the associated infrastructure.
The first well was closed in August 2024, but the shutdown has proceeded much more slowly than the original one-year timetable established through the referendum and Constitutional Court process. The government developed a longer closure plan under which wells would be taken offline in stages, with the complete removal of infrastructure extending toward the end of the decade.
Production records show that Block 43 remained active in 2026. It supplied approximately 41,000 barrels per day in mid-April, making it responsible for close to nine percent of national output. Closing the block therefore has direct consequences for Petroecuador’s production, export revenue and ability to finance other investments.
Replacing these barrels will not be simple. Production gains from mature fields normally require repeated drilling and technical intervention, while opening new Amazonian areas can face lengthy environmental, social and legal processes. The country must also fund the safe closure of wells, the removal of infrastructure and the restoration of affected sites.
Yasuní has consequently changed the central question facing the industry. Ecuador is no longer deciding only how to increase production. It must determine which resources can still be developed, under what environmental conditions and with what level of public and Indigenous approval.
Pipelines Across the Andes Remain a Strategic Weakness
Ecuador’s oil is produced east of the Andes but exported and largely refined on the Pacific coast. This geography makes pipelines essential to the entire industry.
The state-operated Sistema de Oleoducto Transecuatoriano, commonly known as SOTE, carries crude from the Amazon toward the Balao terminal near Esmeraldas. The Oleoducto de Crudos Pesados, or OCP, was developed to provide additional capacity for heavier crude. Together, the two systems connect inland fields with refineries, storage facilities and international markets.
Their importance creates a major concentration of risk. Landslides, earthquakes, heavy rainfall and river erosion can interrupt both pipelines and force producers to close wells when storage capacity becomes limited. The erosion advancing around the Coca River has become particularly serious, requiring temporary bypasses and plans for permanent rerouting.
A rupture of the SOTE pipeline in March 2025 spilled more than 25,000 barrels of oil after a landslide. The incident affected rivers, beaches, agricultural land and nearby communities, while the pipeline remained closed for several days. In July of the same year, heavy rain and erosion threats led both SOTE and OCP to suspend pumping. Petroecuador declared force majeure and national production fell by approximately 133,000 barrels per day during the disruption.
These events demonstrate that Ecuador’s production capacity cannot be considered separately from transport reliability. Additional wells will produce limited economic value if the country cannot move their crude safely and consistently across the Andes.
Pipeline investment is therefore as important as upstream drilling. Route changes, slope monitoring, river management, emergency storage and faster response systems will determine whether Ecuador can reduce the frequency and cost of future shutdowns.
Refining Problems Keep Ecuador Dependent on Imported Fuels
Ecuador exports crude oil while importing substantial volumes of gasoline, diesel, liquefied petroleum gas and other refined products. This apparent contradiction results from the size, configuration and reliability of the domestic refining system.
Petroecuador operates three commercial refineries with combined nameplate capacity of approximately 175,000 barrels per day. The 110,000-barrel-per-day Esmeraldas refinery is the largest, followed by La Libertad and the smaller Shushufindi facility.
Esmeraldas is essential to domestic fuel supply, but repeated maintenance problems and operational interruptions have limited its performance. An earthquake in April 2025 damaged parts of the refinery and forced a temporary shutdown. A fire interrupted operations the following month, while another fire affected the facility in March 2026. Each outage increases the need for contingency imports and places additional pressure on public finances.
The refineries also cannot always convert Ecuador’s crude slate into the exact mix and quality of fuels required by the domestic market. Heavy crude and older processing units can produce large volumes of fuel oil while the economy needs cleaner gasoline, diesel and aviation fuel. Ecuador can therefore export crude and lower-value products while purchasing more expensive finished fuels.
The government’s 2025–2029 hydrocarbons investment plan includes a proposed high-conversion refinery project at La Libertad, with a stated capacity increase of 75,000 barrels per day. A successful project could reduce import dependence, but financing, construction costs, technology selection and long-term crude availability will determine whether the proposal advances beyond planning.
Ecuador Must Replace Declining Barrels Without Repeating Past Expansion
The government’s investment plan identifies upstream, offshore and Intracampos projects that it says could eventually add more than 336,000 barrels per day. This figure describes potential rather than assured production. New output would require major capital commitments, successful exploration, commercially attractive contracts and dependable transport infrastructure.
The more immediate path is likely to involve smaller gains from mature fields, private investment in existing blocks and better recovery from known reservoirs. These additions may offset natural decline, but they are unlikely to transform production quickly.
Ecuador’s oil outlook will be determined by whether it can maintain older fields, protect its pipeline network, improve refinery performance and attract investment under stable contractual conditions. At the same time, the Yasuní decision places a clear limit on development in one of the country’s most sensitive regions.
Oil will remain important to exports and government revenue, but the future industry is likely to be more selective. Growth will depend less on ambitious national targets and more on the ability to develop approved resources reliably, finance essential infrastructure and operate within the environmental and political boundaries established by Ecuadorian society.
