Two Flames on the Borneo Coast

   

For half a century, Lumut has helped sustain Brunei’s prosperity. Now, a larger neighbour competes for Asian buyers while regional partnerships promise fresh gas. His Majesty has called for a clear path. Can Brunei turn today’s market opportunity into lasting strength—or will higher prices merely buy a little time?

 

The Gulf War has made Borneo gas strategic. Brunei must now compete with Sarawak and depend on Malaysia at the same time

Since March, a war in the Gulf has redrawn the map of Asian energy security. Brunei sits on the right side of that map, but on a coastline it shares with a far larger supplier.

Iranian attacks on Qatar’s Ras Laffan complex in March damaged two liquefied natural gas (LNG) trains that may take three years to repair. QatarEnergy is now producing very little LNG.

Asian spot LNG for October delivery reached US$27 per million British thermal units in September, a 45-month high. Buyers are paying a premium for gas that avoids the Strait of Hormuz.

Cargoes from Borneo reach Japan, Korea, China and Thailand without crossing Hormuz or the Strait of Malacca. In this crisis, geography has become a commercial asset.

But Borneo has two LNG sellers. Brunei’s plant at Lumut and Malaysia’s complex at Bintulu, in Sarawak, are courting the same anxious buyers at the same moment.

It is against this backdrop that two titah, delivered on consecutive days, deserve a second reading.

On 30 September, His Majesty Sultan Haji Hassanal Bolkiah Mu’izzaddin Waddaulah ibni Al-Marhum Sultan Haji Omar ‘Ali Saifuddien Sa’adul Khairi Waddien, Sultan and Yang Di-Pertuan of Brunei Darussalam, chaired the board meetings of Brunei LNG and Brunei Gas Carriers.

The Prime Minister’s Office reported that His Majesty emphasised a clear path towards each company’s potential and the strategic choices needed for long-term competitiveness.

The following day, chairing the Brunei Shell Petroleum (BSP) and Brunei Shell Marketing boards, His Majesty emphasised safety, performance and closer collaboration across the Brunei Shell Joint Venture companies.

Read against the Gulf crisis, the message is timely. A window has opened for Brunei’s gas. The question is whether Brunei can make full use of it before it narrows.

An old plant in a wartime market

Brunei LNG’s plant at Lumut started in 1972, the first LNG export plant in the western Pacific. It is now the longest-running LNG plant in the world.

The company lists five liquefaction trains and up to 7.7 million tonnes of LNG a year. The Government holds 50 per cent, with Shell and Mitsubishi Corporation holding 25 per cent each.

Gas for processing comes from BSP and the Block B joint venture. Actual output depends on the gas available, on maintenance and on operating reliability, not on installed capacity alone.

Buyers have taken notice. Brunei LNG signed a long-term agreement with Japan’s JAPEX on 31 August 2026, following a second deal with Thailand’s PTT in June and one with PetroChina in 2025.

Higher spot prices, however, cannot be read directly as higher earnings for every Brunei cargo. Contract prices are confidential, and a temporary shortage cannot be assumed to support favourable terms for decades.

The gas comes through Malaysia

Brunei’s future supply carries a geopolitical story of its own. An important part will come from Block CA2, in waters whose development was settled through diplomacy with Malaysia.

In March 2009, Brunei and Malaysia signed the Exchange of Letters. Among its key provisions was a Commercial Arrangement Area for joint oil and gas development, and a mechanism for fields straddling both countries’ waters.

In 2010, Petronas and Brunei’s national petroleum company signed a production sharing agreement for Blocks CA1 and CA2. Petronas became the main operator, and CA2 gas was earmarked for Lumut.

That plan is finally becoming real. Mitsubishi Corporation, which holds 18.75 per cent of the project, announced its final investment decision on 7 November 2025.

Mitsubishi targets commercial production around 2030, at about 390 million standard cubic feet of gas a day. Petronas Carigali Brunei has leased a floating production unit from Malaysia’s MISC, designed to process 450 million.

Consider the irony. The plant competing with Sarawak for Asian buyers will run partly on gas from a Petronas-operated field, processed on a Malaysian-owned floating unit.

This is not a weakness in itself. Interdependence between good neighbours can be a source of stability. But it does mean Brunei’s LNG future is partly negotiated, not simply owned.

There is also a timing problem. The Gulf window is open now, in 2026 and 2027. CA2 gas arrives around 2030. Brunei must win and keep buyers with the gas it has today.

The giant down the coast

Petronas lists nine production trains and 29.3 million tonnes of annual capacity at Bintulu. On the published figures, that is nearly four times Lumut’s capacity.

Its trains are also younger, built in stages from 1983 to 2016. Behind them sits Sarawak, which holds about 60 per cent of Malaysia’s gas reserves, according to research house BMI.

That scale allows costs to be spread across greater volumes. The advantage still depends on how well the plant uses its capacity, controls energy costs and avoids outages.

Sarawak is also changing politically. Since 2024, its state oil company, Petroleum Sarawak Berhad (Petros), has asserted the role of sole gas aggregator within the state.

In May 2025, Prime Minister Anwar Ibrahim and Sarawak Premier Abang Johari signed a joint declaration. Petronas keeps its upstream role, Petros leads domestic gas supply, and existing LNG export agreements stand.

Part of Sarawak’s gas roadmap is a gas hub at Miri, just across our western border. Brunei’s neighbour is no longer one voice in Putrajaya, but two, with Kuching speaking for its own gas.

For Brunei, this matters. Any future cross-border gas arrangement, including fields that straddle the boundary, may now need to satisfy Kuching as well as Putrajaya.

Competition with Bintulu is real, but it is not zero-sum. In a crisis, buyers want more suppliers, not fewer. A contract for Bintulu need not mean a lost customer for Lumut.

The window and its clock

The Gulf window will not stay open forever. Reuters reported on 7 October that Qatar’s first North Field East expansion train could begin LNG production in the first quarter of 2027.

A sustained ramp-up, analysts say, still requires unrestricted passage through Hormuz. QatarEnergy has said normal operations could resume within weeks once the strait reopens.

Brunei should pursue the openings available today while preparing for the return of Gulf supply. The premium on Borneo gas may fade well before CA2 produces its first cargo.

There is also a moral dimension. Brunei has friends in the Gulf as well as customers in North-east Asia. Its true interest lies in an early end to the conflict, not in profiting from it.

What clearer choices require

Closer collaboration across the joint ventures could help coordinate maintenance, share expertise and improve planning. The test will be safer operations, fewer disruptions and stronger financial results.

Efficiency must not come at the cost of dependable delivery. A cheaper operation that suffers avoidable outages would undermine the very reputation on which a long-term supplier depends.

Workforce development also featured in the board discussions. Retaining experienced staff and preparing Bruneian technical workers will sustain the knowledge on which Lumut’s future depends.

Brunei must also decide how much investment Lumut needs for the CA2 era. That requires evidence on equipment condition, maintenance costs and expected gas supply, not on the plant’s age alone.

Processing additional regional gas for a fee may warrant a feasibility study. It would need spare capacity at Lumut and trust across three capitals: Bandar Seri Begawan, Putrajaya and Kuching.

The 2009 Exchange of Letters shows such trust can be built. It turned a difficult boundary question into a shared commercial arrangement that now feeds Lumut’s future.

The stakes are national. Oil and gas made up 45.1 per cent of Brunei’s gross domestic product in the first quarter of 2026, at current prices.

Commercial negotiations require confidentiality. Even so, Bruneians can reasonably expect an explanation of the broad direction, major milestones and national benefits of these investments.

For more than half a century, Lumut has helped sustain Brunei’s prosperity. Bintulu’s scale now reminds us that experience must be backed by investment, secure gas and disciplined execution.

The Gulf war has made Borneo gas strategic. His Majesty’s call for a clear path points to the longer task: keeping Lumut competitive, with Malaysia as both rival and partner, after the crisis passes.
