Where the Gas Went: Fixing Leaks to Boost Savings and Energy Security in Indonesia

STORY HIGHLIGHTS

  • 80% of methane emissions from oil and gas operations in ASEAN can be reduced at zero net cost and often at a profit.
  • A survey of over 21,000 components at PT Badak LNG cost less than US$50,000, and the gas recovered is expected to generate roughly three times that in revenue, with a payback period of just four months.
  • The Badak LNG pilot found 247 leaks in under two weeks. Replicating this approach across Pertamina's full asset base could capture an additional 4,000 tonnes of methane annually.

Where the Gas Went: Fixing Leaks to Boost Revenue and Energy Security in Indonesia

Every year, around 500 million cubic meters of natural gas silently escape from oil and gas operations across ASEAN (The Association of Southeast Asian Nations) countries. At local prices, this is enough gas to power 1.5 million households, potentially generating $90 million in annual revenue.

Most of this lost gas is methane, one of the most potent greenhouse gases. Methane is nearly 30 times more potent than carbon dioxide at trapping heat.

The good news is that most of this wasted gas and the associated harmful emissions are preventable. More than 80 percent of methane emissions from oil and gas operations in ASEAN countries can be reduced at zero net cost, and often at a profit. That means more gas available to boost energy security, while also providing a safer operating environment for workers and reducing emissions.

In Indonesia, oil and gas revenues remain critical to financing the country’s economic development. Every cubic meter of gas that escapes into the atmosphere represents a lost opportunity to enhance efficiency while generating additional revenue. Across Southeast Asia, where energy demand is rising quickly, capturing gas rather than letting it escape into the air also reduces the need for additional production or imports.

Leaks are also a safety concern. Even small releases from valves or seals increase the risk of accidents. Fixing them improves safety, especially when done through routine leak detection and repair (LDAR) programs.

Capturing the opportunity

Methane survey at gas facility
The World Bank’s Global Flaring and Methane Reduction (GFMR) Partnership helps developing countries turn the currently wasted gas into opportunity by identifying and accelerating solutions for gas flaring, venting, and methane reduction. Our work program includes targeted grant funding, technical assistance, policy and regulatory advisory support, and finance mobilization.

In December 2025, GFMR partnered with Indonesia’s state-owned operator, Pertamina, to carry out an intensive LDAR campaign at the PT Badak NGL (Natural Gas Liquefaction) plant, one of the country’s largest and oldest facilities; its last train was built in 1998.

In less than two weeks, the team found over 247 significant leaks. Around 100 were repaired on the spot, and a further 80 leaks were addressed in the last few months. The remaining leaks have been logged for follow-up during more comprehensive maintenance.

From invisible losses to measurable savings

Methane survey
The impact was immediate. On-the-spot and follow-up repairs reduced methane emissions by an estimated 145 tonnes per year at a single facility. Once the remaining leaks are fixed, annual reductions are expected to reach nearly 200 tonnes. Upon completion of all repairs, the program is expected to achieve an abatement cost of about $9 per tonne of CO2e reduced over just one year, making it one of the lowest-cost emissions-reduction options available at this speed and scale.

The economic benefits are just as compelling. The entire survey cost less than US$50,000. The gas saved is expected to generate revenue worth roughly three times the cost of the survey, with a payback period of just four months.

Scaling regional impact

Looking across Indonesia, Pertamina’s broader portfolio offers significant opportunities to identify and repair leaks, especially in many older facilities, thereby further increasing gas savings and reducing emissions.

By replicating this approach across its broader asset base in 2026, Pertamina could capture an additional 4,000 tonnes of methane, avoiding roughly US$3 million in lost gas each year.

Applied across all ASEAN, the cumulative impact on boosting government revenues and energy security, while also reducing emissions, would be significant.

The lesson from the collaboration at PT Badak NGL is simple and needs to be shared widely with governments industry around the world: at a time when many countries are seeking affordable and reliable energy, LDAR programs are often a quick and inexpensive solution.. They now need to be developed and deployed at scale, in a long-term, programmatic manner, not just in Indonesia but also across the wider ASEAN region and anywhere oil and gas is produced around the world.
