Thailand Oil & Gas Market Intelligence
PTT Group (SET: PTT) anchors Thai oil & gas with FY2024 consolidated revenue ~THB 2.8T spanning upstream (PTTEP), refining (TOP, IRPC), petrochemical (PTTGC), retail (OR). Bangchak (BCP) is the main independent competitor. Thailand imports crude, exports refined products.
Key takeaways
- 1
PTT Group (SET: PTT, FY2024 consolidated revenue ~T) is Thailand's integrated oil & gas holdco, controlled ~ by Ministry of Finance, Vayupak. Group consolidates upstream PTTEP, downstream PTTGC, refiners TOP, IRPC, retail OR, power GPSC. PTT Group alone accounts for ~ of SET total market cap.
- 2
Thai refining capacity is ~1,280 thousand barrels per day (1.28 mbpd) across six refineries: Thai Oil Sriracha ( bpd, TOP), IRPC Rayong ( bpd), Bangchak Bangkok, Sriracha ( bpd combined post-Esso), SPRC Map Ta Phut ( bpd, Chevron-linked), ESSO Sriracha now Bangchak ( bpd acquired 2023), and Fang Northern (small). Thailand is a net importer of crude but net exporter of refined products, petrochemicals.
- 3
Upstream: Gulf of Thailand Bongkot, Erawan fields produce the majority of domestic gas; PTTEP operates both under PSCs (G1/61, G2/61) won in 2018 auction. Production is in managed decline; LNG imports increasingly fill the gap for power, industrial gas demand.
- 4
Retail fuel is dominated by PTT Station (OR, ~2,200 sites, ~ market share), Bangchak (post-Esso acquisition, ~1,800 sites, ~), Shell, Esso brand (remaining via Bangchak), smaller operators. Oil Fuel Fund (OFF) administers diesel, LPG subsidy; persistent deficit since 2022 energy crisis creates cross-subsidy obligations on refiners, retailers.
- 5
Our read: Thai oil & gas is a state-linked integrated platform with PTT as the de-facto national champion; Bangchak the primary independent alternative. Near-term variables: global crude, petchem cycle, Oil Fuel Fund repayment path, Gulf of Thailand field depletion pace. Medium-term: LNG import mix, energy-transition capex (PTTEP clean-energy, PTTGC bio-based, BCP biofuels, solar), regional expansion (PTTEP Mozambique LNG, Oman).
Executive summary
What this report covers, and the thesis in one paragraph
Thailand's oil & gas industry is a state-linked integrated platform anchored on PTT PCL (SET: PTT), the Ministry-of-Finance-controlled holdco whose consolidated FY2024 revenue of approximately T makes it the largest company in Thailand by revenue and approximately of SET total market cap. PTT Group consolidates five listed subsidiaries across the value chain: PTTEP (SET: PTTEP, upstream E&P, FY2024 revenue ~, ~ BOED of sales), PTT Global Chemical (SET: PTTGC, downstream petrochemical, ~), Thai Oil (SET: TOP, largest refiner at bpd, ~), IRPC (SET: IRPC, integrated refiner, petrochemical, ~), and PTT Oil and Retail Business (SET: OR, retail fuel, Cafe Amazon, ~). PTT also anchors power subsidiary Global Power Synergy (SET: GPSC) covered separately.[, , , , , ]
The independent tier is led by Bangchak Corporation (SET: BCP), which materially re-rated in 2023 when it acquired Esso Thailand's Sriracha refinery ( bpd) plus ~700 retail stations plus the Mobil lubricant business from ExxonMobil. Post-acquisition Bangchak operates ~ bpd of refining capacity across Bangchak, Sriracha and runs ~1,800 fuel retail sites β structurally the second-largest retail fuel network after PTT OR. SPRC Map Ta Phut ( bpd, Chevron-linked) is the other material independent refiner but is privately held. Bangkok Aviation Fuel Services (SET: BAFS) is the specialty aviation-fuel operator at Suvarnabhumi, Don Mueang. Together, these operators define the listed-universe coverage of Thai oil & gas.[, , ]
Our thesis: Thai oil & gas is a cycle play with defensive state-backing. Near-term variables are (a) global crude, refining-margin cycle (Singapore complex gross-refining-margin is the key reference); (b) petrochemical-margin cycle (naphtha vs olefin vs polymer spreads); (c) Oil Fuel Fund deficit repayment schedule through 2026-2028; (d) Gulf of Thailand Bongkot, Erawan depletion pace vs LNG import substitution. Medium-term: energy-transition capex (PTTEP clean-energy JVs, PTTGC bio-based, Allnex coatings, BCP biofuels, solar-utility arm), regional expansion (PTTEP Mozambique LNG, Oman Block 61), and Thai domestic fuel-demand trajectory as EV adoption accelerates (see Automotive & EV report).[, , , , ]

Thai Oil (TOP): Refining Margin Cycle and Petrochemical Integration
Thai Oil (SET: TOP) posted FY2024 revenue of THB 455.86B and net income of THB 14.58B against a Singapore complex GRM averaging USD 5.0-6.0/bbl (vs USD 7.1/bbl in 2023). FY2024 EBITDA mix: Petroleum and Lube THB 12.79B (70%), Petchem THB 1.64B (9%), Power THB 1.90B (10%), Others THB 1.90B (10%). The Clean Fuel Project (CFP) β a 275K to 400K bpd capacity expansion plus residue-upgrading unit β is now slated for Q3 2028 commercial operations, with an additional THB 63.03B (USD 1.78B) capex injection plus THB 17.92B in capitalised interest, after the original UJV main-contractor was terminated in April 2025. Petrochemical integration runs through Thai Paraxylene (900,000 tonnes per annum aromatics), benzene, toluene, mixed xylenes, and Top Solvent (Vietnam plus Sak Chaisidhi 80%-owned hydrocarbon solvents).

Thailand Biodiesel & Renewable Diesel Market Intelligence
Thailand consumed roughly 4.4 million litres of B100 methyl ester per day in 2024 (~1.6-2.1 million tonnes per year), absorbing 30-35% of domestic CPO supply through the B7 plus B20 mandate. Bangchak Corporation (SET: BCP) anchors capacity via the BBE Ayutthaya joint venture with UAC and now operates ASEAN's first commercial HEFA SAF unit at Phra Khanong, supported by the Fry to Fly used-cooking-oil collection programme. PTT Group, Thai Oil (SET: TOP), IRPC (SET: IRPC) handle refinery-gate blending; Verasuwan, PA Renewable Energy, Patum Vegetable Oil and other specialty plants hold the long tail. The AEDP 2024-2037 roadmap fixes B7 as the diesel floor, ramps SAF from 1% (January 2026) to 8% (2036), and frames the structural variables: EV diesel-pool erosion, EUDR palm-traceability compliance, and HVO drop-in renewable diesel as the next-leg pivot.

IRPC: Integrated Petrochemical Margin Through the Cycle
IRPC FY2024 net loss THB 5.2B on net sales THB 281.7B (-6% YoY) and crude intake 71.6M barrels (+2% YoY). Singapore complex GRM averaged USD 4.8 per barrel in 9M 2024, down from USD 7.2 in 9M 2023. China PP-naphtha spread hit USD 191 per tonne in early 2024, the lowest since ICIS records began in 2003. PTT owns 45.05% of IRPC; Rayong complex integrates 215K bpd refining with 732 KTA propylene, 931 KTA polyolefins, 383 KTA styrenics (ABS, PS, EPS, SAN). Specialty-tilted product mix is the through-cycle differentiator versus PTTGC and Thai Oil.
