Indonesia still produces crude oil domestically, including Duri Crude from the Duri Field, which has relatively heavy crude characteristics. However, domestic oil production is not sufficient to meet all of the country’s refinery and energy needs.
As a result, Pertamina uses a combination of domestic and imported crude oil as refinery feedstock. Pertamina explains that its refineries process blended crude, with crude selection determined by the capabilities and configuration of each refinery. Pertamina Kilang Internasional — Our Business

For bitumen production, crude characteristics and refinery configuration are important because heavy products such as vacuum residue can serve as feedstock or a component in bitumen production. Pertamina’s product documentation lists both asphalt and vacuum residue among its products. Pertamina One Solution — Bitumen Product Documentation
Meanwhile, Indonesia’s Energy Minister stated in March 2026 that around 20–25% of Indonesia’s crude oil imports were sourced from regions associated with the Strait of Hormuz supply route.
For Road Knowledge Hub ID, understanding the relationship between crude supply, refinery configuration, heavy residue, and bitumen is important for understanding the material supply chain behind road construction.
Does Indonesia Have Its Own Crude Oil?
Yes.
Indonesia still produces crude oil domestically from several fields.
One example is the Duri Field in the Rokan Block, which produces Duri Crude, a relatively heavy crude. Indonesia’s Ministry of Energy and Mineral Resources identifies Duri as heavy crude and has described the use of steam-flood technology to support production from the field. Indonesia Ministry of Energy and Mineral Resources — Duri Field
Data from the Indonesian Petroleum Association also lists Duri Crude at around 22° API gravity, indicating relatively heavy crude characteristics. Indonesian Petroleum Association — Review of Steamflooding in Duri Field
So Indonesia is not completely dependent on imported oil.
The issue is that domestic production volumes and crude characteristics do not always match the country’s overall refinery and market requirements.
Why Does Indonesia Still Import Crude Oil?
One reason is that domestic crude production is not enough to meet total refinery requirements.
But volume is not the only consideration.
Crude characteristics also matter.
Not all crude oils are the same.
Some are relatively light, while others are heavier and have different sulfur levels and hydrocarbon distributions.
Refineries therefore need to select or blend crude according to their processing capabilities.
Pertamina explains that its refineries use a Crude Acceptance Matrix (CAM) to evaluate crude feedstocks, including their technical characteristics, impact on final products, efficiency, reliability, and economics. Pertamina Kilang Internasional — Our Business
This means:
It is not simply about whether Indonesia has oil. It is also about whether the available crude is suitable for the refinery.
What Does Heavy Crude Have to Do With Bitumen?
Bitumen is associated with the heavy fractions produced during petroleum refining.
During crude oil processing, the crude is separated into different fractions. Very heavy material can be processed further, including through vacuum distillation, to produce vacuum residue.
Vacuum residue is one of the heavy products generated during petroleum processing and can be used as a feedstock or component in bitumen production, depending on the process and required specification. Technical literature from the Asphalt Institute describes vacuum-distillation residue as a material used in bitumen production. Asphalt Institute — The Bitumen Industry: A Global Perspective
Therefore, the characteristics of the crude entering a refinery can influence the type and quantity of heavy products available for further processing.
Does Heavy Crude Automatically Produce More Bitumen?
Not necessarily.
This distinction is important.
Heavy crude generally contains a larger proportion of heavy fractions than lighter crude. However, the quantity and quality of vacuum residue or bitumen that can ultimately be produced still depend on:
- Crude characteristics.
- Refinery configuration.
- Operating conditions.
- Available processing units.
- Target product specifications.
- Crude blending.
The more accurate relationship is:
Crude Characteristics → Refinery Processing → Heavy Residue → Further Processing / Blending → Bitumen
Not:
Heavy Crude → Directly Becomes Asphalt
Why Might Imported Crude Be Needed by Refineries?
Because refineries may require a combination of crude characteristics.
Pertamina states that its refineries process blended crude and use a Crude Acceptance Matrix to determine the suitability and processing limits of particular crude types. Pertamina Kilang Internasional — Our Business
Domestic and imported crude can therefore be used together to achieve a feedstock combination that is appropriate for refinery operations.
This also helps explain why Indonesia can continue importing crude even while producing crude domestically.
What Does the Strait of Hormuz Have to Do With It?
This is where geopolitics enters the picture.
A portion of Indonesia’s imported crude comes from the Middle East.
According to Indonesia’s Energy Minister in March 2026, approximately 20–25% of Indonesia’s total crude imports came from regions associated with the Strait of Hormuz supply route.
The Strait of Hormuz is one of the world’s most strategically important energy shipping routes.
When disruption or geopolitical risk increases in the area, the impact is not limited to potential physical shipping delays.
Global markets can also respond through:
- Crude oil prices.
- Freight costs.
- Marine insurance.
- Tanker availability.
- Shipping route changes.
- Risk premiums.
Pertamina stated in March 2026 that it was also seeking alternative import sources in response to distribution dynamics around the Strait of Hormuz. Pertamina Seeks Alternative Import Sources During Strait of Hormuz Disruptions
Can Crude From Other Regions Still Be Affected?
Yes.
This is one of the most important concepts in understanding the global oil market.
Suppose Indonesia purchases crude from a country outside the Middle East.
That crude is still part of the global oil market.
If a major disruption occurs along an important energy trade route, global oil prices and transportation costs can change.
As a result, crude from other sources can also become more expensive or more costly to transport.
The impact does not necessarily have to be:
“Indonesia’s crude must physically pass through the Strait of Hormuz.”
It can also happen through:
Hormuz Disruption → Higher Global Supply Risk → Crude Price Changes → Higher Freight & Insurance → Higher Refinery Feedstock Cost
💡 Field Note
Indonesia has its own crude oil, but that does not mean Indonesia is isolated from the global oil market. To understand bitumen pricing and availability, look at the chain: Crude Oil → Refinery → Heavy Residue / Vacuum Residue → Bitumen → Logistics → Asphalt Market
Field Note
Why Does This Matter to the Road Construction Industry?
Bitumen is one of the key materials used to produce asphalt mixtures.
If refinery feedstock costs or availability change, the impact can move through the following chain:
Crude → Refinery → Bitumen → Hot Mix → Paving → Project Cost
For road projects requiring large quantities of bitumen, even relatively small changes in material prices can have a meaningful impact on total project costs.
This is why bitumen procurement should not focus only on:
“What is Supplier A’s price?”
It should also consider:
“Where does the feedstock come from, and how exposed is the supply chain to disruption?”
🎯 Key Takeaway
Indonesia has domestic crude oil production, including heavy crude such as Duri Crude. However, refinery requirements and crude characteristics mean Indonesia continues to use a combination of domestic and imported crude.
For bitumen, crude characteristics and refinery configuration determine how heavy fractions such as vacuum residue can be utilized in bitumen production.
Because some Indonesian crude imports are sourced from regions connected to the Strait of Hormuz supply route, geopolitical disruption in the Middle East can affect prices, logistics costs, and supply risks, even when the crude itself comes from another country.
The relationship between geopolitics and asphalt prices is therefore not direct.
It is better understood as:
Geopolitics → Crude Market → Refinery Feedstock → Bitumen Supply → Logistics → Asphalt Price

Does Indonesia produce its own crude oil?
Why does Indonesia still import crude oil?
Is Duri Crude considered heavy crude?
What is the relationship between vacuum residue and bitumen?
