Boosting Indonesia’s energy resilience through advanced technology

As Indonesia’s energy needs grow, we’re developing new ways to continue supporting the country and its people’s development.

This includes taking innovative steps and leveraging advanced technology to improve oil production at our Banyu Urip operations, part of Indonesia’s vast Cepu Block oil field. Two key methods we’re using — Low Dosage Acid (LDA) and Gas Shut Off (GSO) — help unlock more barrels from underground while keeping operations safe and cost-effective.

Low Dosage Acid (LDA)
A safe and controlled process where we inject a small amount of acid into rocks, creating a chemical reaction partially dissolving scale and blockages, reopening oil flow paths.

Gas Shut Off (GSO)
Sometimes, gas begins flowing into wells earlier than expected, which can reduce oil production. GSO uses chemicals to isolate the gas flow and redirect it, allowing more oil to enter the well.

These are ExxonMobil’s first-of-their-kind technologies, applied for the first time in Indonesia. This demonstrates how we leverage our global technology and wells organisations to identify solutions that can deliver real value.

Raising Indonesia’s energy resilience

The Cepu Block currently accounts for almost a third of the country’s total oil output, having produced more than 700 million barrels — nearly double its original target of 450 million barrels — with the potential to exceed 1 billion barrels over its lifetime. Since production began, it has contributed about US$35 billion, or roughly Rp 586 trillion, to Indonesia’s economy.

Through innovation, collaboration, and applying advanced technology, we’ll continue to maximize oil production from the Cepu Block and strengthen Indonesia’s energy resilience.
