Thailand Oil And Gas Upstream Market: Market Size & Forecast 2026

Thailand's oil and gas upstream market encompasses exploration, field development, and production activities across onshore and offshore basins, with the majority of operations concentrated in the Gulf of Thailand. The market was valued at approximately $4.33 billion in 2025, reflecting steady demand for domestic energy resources and sustained production from mature fields. With crude oil and condensate production averaging roughly 244,000 barrels per day in 2025, Thailand maintains its position as a notable producer within Southeast Asia, though the country still relies on imports to meet a significant portion of its total energy demand.

• •Market valued at approximately $4.33 billion in 2025 with a 4.4% CAGR growth trajectory
• •Current production stands at roughly 244,000 barrels per day, projected to reach 274,000 barrels per day by 2030
• •Import growth rate declined by approximately 2.82% between 2023 and 2024, signaling a move toward greater domestic supply

The primary driver of market expansion is Thailand's national energy security agenda, which prioritizes maximizing domestic hydrocarbon production to reduce reliance on imported energy. Government policies supporting upstream investment, including production-sharing contracts and favorable fiscal terms, have encouraged both state-owned and international operators to maintain and expand exploration activities. Additionally, ongoing advances in enhanced oil recovery techniques and the development of marginal fields are extending the productive life of existing reserves, contributing to incremental output growth.

• •National energy self-sufficiency goals driving policy support for domestic exploration and production
• •Declining import dependency, reflected in a negative growth rate for oil and gas imports, reinforcing focus on local output
• •Mature field development and enhanced recovery projects extending production from established Gulf of Thailand assets

The Thai upstream market is predominantly offshore, with the Gulf of Thailand serving as the core producing region containing the majority of the country's proven reserves. Conventional resources dominate the resource base, while unconventional exploration remains limited compared to regional neighbors. Within the broader Asia-Pacific upstream context, Thailand represents a mature but strategically important market, positioned between fast-growing Southeast Asian producers and established energy hubs like Australia and Indonesia.

• •Offshore operations in the Gulf of Thailand account for the bulk of upstream activity and reserves
• •Conventional oil and gas resources form the foundation of the market, with limited unconventional development
• •Thailand's production profile and import trends place it as a stabilizing force within the Southeast Asian energy mix

What are the recent trends and outlook?

Looking ahead, Thailand's upstream market is expected to benefit from targeted exploration in deeper water zones and the progressive development of stranded or underutilized gas reserves. Digitalization and advanced reservoir management technologies are being increasingly adopted to optimize output from mature fields. However, the market must also navigate challenges including declining discovery rates in mature basins, evolving environmental regulations, and global energy transition pressures that may influence long-term investment priorities.

• •Deepwater exploration and marginal field development represent near-term opportunities for reserve growth
• •Digital oilfield technologies and enhanced recovery methods improving operational efficiency in mature assets
• •Global energy transition dynamics creating both headwinds for fossil fuel investment and opportunities for natural gas as a transition fuel
