There is a photograph in the PETRONAS Twin Towers gallery that shows the signing ceremony for Malaysia’s first LNG sale-and-purchase agreement with Tokyo Electric Power Company in 1972. The deal — pioneering at the time, modest by today’s standards — committed Malaysian LNG to Japanese buyers before a single liquefaction train had been built at Bintulu.
That sale preceded Malaysian LNG production by seven years. The first cargo didn’t leave Bintulu until 1983. What the gap between signing and first delivery represents is the structure on which the global LNG industry was built: long-dated supply commitments, anchored by sovereign credit on both sides, with development finance bridging the capital requirement in between.
PETRONAS has operated in that framework for more than five decades. The company’s LNG strategy in 2025 is shaped by that history — and by the ways in which the market has moved beyond it.
What PETRONAS actually produces
The Malaysia LNG complex at Bintulu, Sarawak, is one of the largest single-site LNG export operations in the world. MLNG (Malaysia LNG Sdn Bhd) operates nine liquefaction trains across three phases of development:
- MLNG Satu (Phase 1): Three trains, commissioned 1983–1984, original capacity approximately 8 MTPA
- MLNG Dua (Phase 2): Three trains, commissioned 1994–1995, approximately 8 MTPA
- MLNG Tiga (Phase 3): Three trains, commissioned 2003, approximately 7.8 MTPA
Total nameplate capacity at the Bintulu complex is approximately 29.3 MTPA. In practice, actual production runs below nameplate due to gas feed availability from upstream Sarawak fields, planned and unplanned maintenance, and optimisation across the train portfolio.
The Bintulu complex is supplied primarily by gas from Sarawak offshore fields operated by PETRONAS Carigali and its joint venture partners. The gas supply infrastructure — subsea pipelines, onshore processing, compression — represents decades of upstream capital investment. The challenge PETRONAS faces is that the major Sarawak gas fields underpinning MLNG production are mature. PETRONAS’s Annual Report 2024 confirmed ongoing reserve replacement activity in deepwater Sarawak, but production rates from legacy fields continue their natural decline curves.
Gas supply management: the upstream constraint
Reserve replacement at MLNG’s supply fields is not a crisis — but it is a continuous challenge that shapes PETRONAS’s commercial decisions in ways that external observers sometimes underestimate.
PETRONAS has pursued several strategies to sustain gas supply to Bintulu:
Deepwater Sarawak development — The Rotan, Kasawari, and Jerun gas fields in deepwater Sarawak are among the most significant new supply additions. The Kasawari gas development, first gas expected around 2024–2025, is notable not just for its supply volumes but for its associated carbon capture and storage component — a first for Malaysian upstream and a response to the growing sustainability scrutiny on LNG exports.
Sabah gas integration — Sabah’s offshore gas resources, historically constrained by limited monetisation infrastructure, are being progressively connected to the national gas system. The Sabah-Sarawak Gas Pipeline provides the physical connection; the commercial question of how Sabah gas is priced and allocated between domestic power, LNG export, and industrial uses remains a live policy discussion within Malaysia.
Partial LNG imports — This is the structural shift that few outside Malaysia fully appreciate. PETRONAS operates regasification terminals at Melaka and Pengerang, importing LNG into Peninsular Malaysia where domestic gas production from the Malay Basin cannot fully meet demand. The company is, simultaneously, among the world’s largest LNG exporters and a growing LNG importer. Managing these two sides of the ledger requires a sophisticated trading and logistics capability that PETRONAS has built up significantly over the past decade.
Trading capability and portfolio evolution
PETRONAS Global Trading (PGT), based in Kuala Lumpur with operations in London, has grown its spot and portfolio trading activity substantially since 2018. The company now participates actively in spot LNG tender markets across Asia and, increasingly, in Atlantic basin trading.
This is a significant departure from the company’s historical posture as a long-term contract seller that left trading to others. The evolution reflects several pressures:
- Long-term Bintulu supply contracts with Japanese and Korean buyers contain volume tolerance bands and diversion clauses that create residual volumes for PETRONAS to manage commercially
- Domestic gas demand in Malaysia is growing, but not in lockstep with Bintulu production — surplus above domestic and contracted volumes needs a market
- PETRONAS’s credit quality allows it to participate in markets that require strong counterparty standing
For Asian sovereign buyers conducting spot or short-term LNG tenders, PETRONAS is now a regular bidder. For project developers seeking PETRONAS as a potential off-take partner for new LNG infrastructure, the company’s commercial appetite and creditworthiness make it a viable anchor counterparty — but the negotiation requires understanding PETRONAS’s dual position and the constraints it creates.
The Sarawak CO₂ question
Kasawari’s CCS component reflects a challenge that applies to MLNG’s entire production portfolio. Sarawak’s gas contains elevated CO₂ concentrations in several fields — historically stripped and vented, which creates a significant carbon intensity problem for LNG sold to buyers under pressure to decarbonise their gas supply chains.
The Kasawari CCS project proposes to store stripped CO₂ offshore in the same geological formations from which gas is produced. If it works at commercial scale and cost, it provides a template for addressing the carbon intensity of Sarawak LNG more broadly. If it encounters geological, regulatory, or commercial obstacles, the carbon intensity issue remains unresolved.
Japanese buyers in particular — several of whom have public commitments to net-zero supply chains — are watching Kasawari closely. The same applies to European utilities that have signed Malaysian supply agreements and face growing pressure from investors and regulators on supply-chain emissions.
Pengerang: Malaysia’s LNG hub ambitions
The Pengerang Integrated Complex in southern Johor is PETRONAS’s most strategically ambitious infrastructure project of the past decade. Originally conceived primarily as a petroleum refining and petrochemical complex — RAPID (Refinery and Petrochemical Integrated Development) — the complex includes the Pengerang Regasification Terminal, which has capacity to receive and distribute LNG into the Peninsular Malaysian grid.
Pengerang’s location adjacent to Singapore, its access to the Strait of Malacca shipping lane, and its integrated downstream facilities create the potential for a regional LNG hub function: a terminal that does more than just regasify, but serves as a transshipment, trading, and price discovery centre for regional LNG trade.
Singapore’s existing role as a regional LNG hub is well-established through Singapore LNG Corporation’s terminal on Jurong Island. Pengerang does not directly compete — it serves a different geographic and regulatory context — but the proximity creates interesting questions about complementarity and competition in regional LNG infrastructure.
Social media pulse
Kasawari CCS is one of the most important LNG decarbonisation projects globally right now. If PETRONAS can make offshore CO2 storage work at scale in Sarawak, it changes the carbon intensity narrative for the entire Southeast Asian LNG export sector. Watching closely.

PETRONAS's dual role as major LNG exporter AND growing importer is an underreported story. The company managing both sides of a national gas balance — exporting from Sarawak, importing into Peninsula — while trading actively in spot markets is operationally complex in ways that simpler NOC models aren't.

What this means for buyers and developers
For sovereign LNG buyers in Asia sourcing from PETRONAS: the company is a reliable long-term counterparty with decades of delivery performance. The risk factors to assess are upstream gas supply longevity, carbon intensity (especially for buyers with decarbonisation commitments), and PETRONAS’s own domestic obligations that take priority over export volumes in gas supply stress scenarios.
For LNG infrastructure project developers seeking PETRONAS as an equity partner or off-take anchor: the company has appetite for well-structured regional projects that align with its portfolio trading strategy. The commercial case needs to connect to PETRONAS’s actual business priorities — supply diversity, trading optionality, regional market access — rather than presenting generic infrastructure investment terms.
The company that signed its first LNG deal in 1972 and received first cargo in 1983 understands how to take a long view. That patience, when aligned with a credible project, is one of the most valuable attributes an LNG infrastructure project developer in this region can access.
