CHAPTER 1 - MARKET SUMMARY
Market Overview
The Thailand Oil and Gas Market operates through an integrated demand chain spanning offshore and onshore production, gas separation and transmission, LNG imports, crude refining and petroleum distribution. Commercial primary energy consumption reached 2,046 thousand barrels of oil equivalent per day in 2024, while petroleum-product consumption averaged 140.6 million litres per day. This scale sustains recurring demand for upstream investment, gas infrastructure and refining services.
The Gulf of Thailand is the market's dominant production cluster because it contains the country's principal producing gas fields and established offshore infrastructure. In 2025, assets operated by the national upstream champion accounted for approximately 82% of natural gas produced in Thailand, with major supply coming from Erawan, Bongkot and Arthit. Concentrated offshore production lowers network duplication but increases dependence on mature-field redevelopment and continuous drilling.

Future Outlook
The Thailand Oil and Gas Market is projected to expand from USD 4,500 million in 2025 to USD 6,507 million by 2032, representing a forecast CAGR of 5.41%. The model implies a 2031 market size of USD 6,173 million. Growth should remain concentrated in offshore gas production, brownfield redevelopment, LNG and gas-network services, selective exploration and refinery optimization. The historical market expanded at an estimated CAGR of 5.03% during 2020-2025, supported by post-pandemic mobility recovery, stronger aviation demand and accelerated restoration of Gulf of Thailand gas output.
Through 2032, market growth is expected to become progressively less dependent on simple petroleum-volume expansion and more dependent on asset productivity, reserve replacement, gas security and infrastructure investment. The Gas Plan framework emphasizes supply security, price stability and reduced exposure to imported LNG, while new exploration acreage expands optionality for domestic resources. Mature-field redevelopment, CCS-linked infrastructure and higher refinery conversion efficiency will create differentiated profit pools. Investors should therefore prioritize operators with low-cost brownfield portfolios, resilient gas-linked cash flows, disciplined project execution and access to existing pipelines, terminals and refining systems.

CHAPTER 8 - INDUSTRY ANALYSIS
Growth Drivers, Challenges & Opportunities
Comprehensive analysis of key factors shaping the Thailand Oil and Gas Market, including growth catalysts, operational challenges, and emerging opportunities across production, distribution, and consumer segments.
Growth Drivers
Restoration of Gulf of Thailand Gas Production
- Major producing assets including G1/61, G2/61, Arthit and S1 remain central to the investment program, with the operator allocating substantial development capital to sustaining output and offsetting natural decline. THB 261 billion planned investment (2025, company-wide) reinforces demand for drilling, subsea, engineering and production services.
- Gas retains a critical power-sector role, accounting for approximately 58% of electricity generation (2024, Thailand). Utilities therefore have strong incentives to secure indigenous production and LNG flexibility, supporting upstream, pipeline and gas-processing investment.
- The principal national operator accounted for approximately 82% of domestically produced natural gas (2025, Thailand), making its field-development cadence a major determinant of national gas supply and service-sector spending.
Tourism, Aviation and Mobility Fuel Recovery
- Jet-fuel consumption rose to approximately 16.2 million litres per day (2024, Thailand), up 18.7% year on year, creating higher throughput requirements for refiners, aviation-fuel suppliers and airport logistics operators.
- Overall petroleum-product consumption reached 140.6 million litres per day (2024, Thailand), increasing 1.8%, sustaining crude-import, refining, storage and distribution economics even as transport electrification progresses.
- Diesel demand remained approximately 68.8 million litres per day (2024, Thailand), reinforcing the scale advantage of integrated refiners and national fuel networks serving logistics, commercial fleets and industrial customers.
New Exploration Acreage and Gas Infrastructure
- The 25th bidding round required work commitments and financial guarantees, including a THB 3 million bid security per block (2025, Thailand), screening for capable operators while mobilizing exploration expenditure.
- Thailand's fifth onshore gas-transmission pipeline project had reached approximately 99.11% progress by June 2025, expanding network resilience and strengthening midstream capacity for future gas flows.
- Gas-market liberalization has expanded access to LNG supply infrastructure, with the regulatory framework supporting multiple licensed shippers and third-party access, strengthening competition in marginal gas procurement. 8 licensed shippers were reported in the latest regulatory review.
Market Challenges
High Structural Import Dependence
- Oil and petroleum-liquids production of approximately 393 thousand barrels per day (2024, Thailand) was far below consumption of 1,372 thousand barrels per day, creating a structural liquids deficit requiring imported crude and products.
- The resulting oil deficit was approximately 979 thousand barrels per day (2024, Thailand), making refinery economics sensitive to international crude differentials, freight rates, foreign exchange and geopolitical disruptions.
- The Gas Plan framework explicitly prioritizes reduction of LNG-import exposure and geopolitical risk, demonstrating that imported gas availability and cost remain material energy-security constraints for power producers and industrial buyers. Gas Plan horizon extends to 2037.
Mature Reserves and Continuous Replacement Requirements
- Thailand's proved natural-gas reserves were approximately 4,819.24 Bcf at end-2025; sustaining production requires regular infill drilling and new-resource conversion because Gulf of Thailand reservoirs are relatively small and compartmentalized.
- Domestic oil production decreased from approximately 488.6 kb/d in 2020 to 395.8 kb/d in 2025, illustrating the depletion pressure confronting upstream portfolios even when individual projects stabilize production.
- Mature offshore facilities require additional brownfield capital, and field-life decisions increasingly depend on redevelopment economics, abandonment liabilities and tie-back potential rather than simple greenfield production growth. Wassana redevelopment alone requires approximately USD 120 million of new facilities investment.
Transport Electrification and Downstream Margin Pressure
- Thailand had approximately 3,429 EV charging stations and 11,467 connectors (2024, Thailand), increasing the practical availability of alternatives to gasoline and diesel for passenger transport.
- Refiners must improve conversion efficiency and product flexibility as road-fuel growth moderates. Thai Oil's complex refinery has approximately 275 kb/d nameplate capacity, demonstrating the scale of assets that must continually optimize yield and margins.
- Integrated downstream operators are simultaneously investing in lower-carbon products and operational restructuring, increasing capital-allocation complexity as conventional fuels remain commercially important while demand composition changes. Bangchak targets refinery capacity of approximately 285 kb/d by 2028.
Market Opportunities
Mature-Field Redevelopment and Brownfield Optimization
- The Wassana redevelopment carries approximately USD 120 million facilities capex and management-estimated IRR above 40% at USD 60/bbl Brent, demonstrating monetizable economics for technically disciplined mature-field investors.
- Operators, offshore contractors and equipment suppliers benefit because new processing platforms, drilling slots and satellite tie-backs extend asset lives and create recurring service revenue. Wassana's updated field life extends to approximately 2043.
- The opportunity requires continued seismic reprocessing, infill drilling and disciplined fixed-price contracting; more than 80% of Wassana facility capex was placed under fixed-price commitments, illustrating execution structures that can reduce development risk.
Carbon Capture and Storage Around Producing Gas Assets
- CCS can create new engineering, monitoring, compression, injection and subsurface-services revenue around mature hydrocarbon infrastructure, allowing operators to monetize existing technical capabilities beyond conventional production. The Arthit field supplies approximately 8% of Thailand's domestic natural-gas demand.
- Upstream operators and engineering contractors benefit from reusing offshore knowledge, reservoirs and facilities, while industrial customers gain a potential route to lower-carbon gas-linked operations. The project is scheduled to begin operations in 2028.
- Commercialization requires storage regulation, long-term liability rules, carbon-price signals and transport infrastructure. The project demonstrates early institutional commitment through a consortium involving an existing Arthit participant with a 4.7619% CCS project interest.
LNG Competition and Gas-System Flexibility
- Gas suppliers can capture procurement and portfolio-management value by combining domestic gas, term LNG and spot LNG, while utilities benefit from diversified contracting. Regulatory reporting identifies 8 licensed gas shippers in the evolving market structure.
- Pipeline and terminal utilization can improve as third-party access expands, supporting infrastructure owners while reducing entry barriers for qualified importers. The latest regulatory review notes 6 shippers had imported LNG.
- The opportunity depends on transparent access codes, competitive procurement rules and disciplined infrastructure expansion; Thailand's Gas Plan explicitly targets security of supply, price stability and lower exposure to LNG-import volatility through 2037.
