Fuel oil consumption in Indonesia continues to increase every year. The Indonesian Petroleum Association (IPA) reports that Indonesia’s fuel consumption reached an average of 232,417 kiloliters per day, or around 1.46 million barrels per day in 2025.
Meanwhile, domestic production capacity is only around 605,300 barrels per day. This condition shows that Indonesia still needs to rely on imports to meet domestic energy demand.
The large gap between consumption and production raises concerns about the sustainability of national energy supply in the future. With continuously rising fuel demand and many industrial sectors still dependent on oil, is Indonesia’s oil reserve still safe for the next 10 years?
How Large Are Indonesia’s Oil Reserves in 2025?
| Oil Reserves Category | Barrels (billion) |
| Proven Reserves | 2.326 |
| Potential Reserves | 2.098 |
The Ministry of Energy and Mineral Resources classifies Indonesia’s oil reserves into two categories:
- Proven Reserves: Oil volumes with a high degree of certainty based on geological data that can be economically produced.
- Potential Reserves: Estimated oil resources that may be economically viable for production in the future.
According to the 2025 Performance Report of the Directorate General of Oil and Gas, Indonesia’s total oil reserves are approximately 4.4 billion barrels, consisting of:
- 2.32 billion barrels of proven reserves
- 2.09 billion barrels of potential reserves
Over the past five years (2021–2025), Indonesia’s oil reserves have remained relatively stable. Compared to 2024, total reserves in 2025 recorded a slight increase.
Indonesia also still holds significant untapped potential. Out of 128 sedimentary basins, 68 remain unexplored. However, converting these into commercial reserves requires substantial investment and long development timelines.

Are Indonesia’s Oil Reserves Enough for the Next 10 Years?
Technically, Indonesia’s oil reserves are sufficient for around 10 years. However, these reserves are not enough to fully meet national consumption without imports.
Based on 2025 data, Indonesia has 2.326 billion barrels of proven reserves. With current production levels of 605,300 barrels per day, Indonesia’s Reserve-to-Production (R/P) ratio stands at around 10.5 years.
This means that if production remains constant and no new reserves are discovered, existing proven reserves could last until around 2035.
However, the picture changes when viewed from the demand side. Indonesia’s oil consumption in 2025 reached around 1.46 million barrels per day, or about 2.4 times higher than domestic production. In other words, domestic production only meets around 41% of national demand.
As a result, Indonesia must import around 854,700 barrels of oil per day, or approximately 312 million barrels per year, to meet domestic needs.
If all national consumption had to be covered solely by domestic reserves (without imports), Indonesia’s proven reserves would only last around 4.4 years.
This indicates that Indonesia is still not fully secure in terms of energy supply. For energy-intensive industries such as smelters, power plants, mining, and heavy manufacturing, this is a critical issue.
Companies that delay energy diversification risk facing supply challenges and volatile cost pressures. On the other hand, businesses that begin planning energy substitution strategies early, such as shifting to LNG (Liquefied Natural Gas), will be better positioned to maintain energy resilience and cost stability in the future.

LNG as a Future Energy Substitution Solution for Cleaner Energy
Amid rising national energy consumption and limited oil reserves, LNG has emerged as a strong alternative for the industrial sector.
LNG is natural gas cooled to approximately -162°C, reducing its volume and making it easier to store and transport.
Compared to oil-based fuels, LNG produces lower carbon emissions and cleaner combustion. By using LNG, companies can improve energy efficiency while supporting emission reduction goals.
LNG also plays an important role in strengthening national energy security. Indonesia has larger natural gas reserves compared to oil reserves.
Therefore, LNG utilization can reduce dependence on fuel oil imports and provide a more reliable energy alternative for industries such as smelters, manufacturing, mining, and power generation.
Integrating LNG into corporate energy strategies early allows industries to better prepare for future energy supply dynamics and fuel price volatility.
This is why PGN LNG Indonesia is here to help ensure LNG energy availability for your industrial operations. As part of Indonesia’s national gas ecosystem, PGN LNG Indonesia provides reliable and integrated LNG solutions to support energy needs across various industrial sectors.
