Indonesia Oil And Gas Market: Market Size & Forecast 2026

Indonesia's oil and gas market encompasses upstream exploration and production, midstream processing and transport, and downstream refining and retail distribution across an archipelago of more than 17,000 islands. Valued at $13.88 billion in 2025, the market is forecast to reach $14.6 billion in 2026, with longer-term projections extending toward $864.6 million in certain segment valuations by 2034, reflecting modest but steady growth. The upstream segment alone accounted for approximately $10.01 billion or 72.10% of total market revenue in 2025, underscoring the critical role of exploration and production activities in the national energy portfolio.

• •Market valued at $13.88 billion in 2025, projected to reach $14.6 billion in 2026
• •Upstream segment dominates at ~72% of total market revenue ($10.01 billion)
• •Current production stands at approximately 637,000 barrels of oil per day

Rising domestic energy demand is the single largest growth catalyst, as Indonesia's expanding economy and growing population continue to push electricity and fuel consumption higher. The Indonesian government has implemented a range of fiscal and regulatory incentives designed to attract foreign investment into underexplored basins and aging fields requiring enhanced recovery techniques. National energy security priorities also drive continued state involvement through Pertamina, the national oil company, which partners with international majors on major production and infrastructure projects.

• •Domestic demand for oil and natural gas is the primary demand-side driver
• •Government incentives and production-sharing contracts attract foreign direct investment
• •Energy security objectives sustain state-led investment through Pertamina

The market is broadly segmented into upstream, midstream, and downstream activities, with upstream exploration and production commanding the largest share of revenue at approximately 72% in 2025. Geographically, conventional oil and gas operations are concentrated in established basins including Sumatra, Kalimantan, and the Natuna Sea, while newer frontier areas such as East Indonesia and the Masela Block draw increasing investor attention. Deepwater and frontier exploration represents a growing sub-segment as onshore reserves mature and technology improvements make previously uneconomical fields viable.

• •Upstream, midstream, and downstream form the three primary market segments
• •Key producing regions include Sumatra, Kalimantan, and the Natuna Sea
• •Deepwater and frontier exploration is an emerging investment area

What are the recent trends and outlook?

Indonesia is pursuing a measured energy transition alongside continued fossil fuel development, with government policies encouraging both upstream investment and the gradual expansion of natural gas and renewable energy capacity. Enhanced oil recovery techniques, digitalization of field operations, and the development of liquefied natural gas infrastructure are expected to sustain output from mature fields. The International Energy Agency's Oil 2025 report underscores the importance of continued investment in Southeast Asia's energy systems to meet rising demand while managing carbon intensity, positioning Indonesia as a key player in the region's evolving energy landscape through 2030 and beyond.

• •Government policies balance upstream oil and gas investment with renewable energy expansion
• •Natural gas and LNG infrastructure development is a near-term priority
• •IEA forecasts sustained regional energy demand growth requiring continued investment through 2030
