Indonesia Has 20 Oil and Gas Basins with Potential for Carbon Storage

ASIATODAY.ID, JAKARTA – Indonesia’s upstream oil and gas has very promising carbon storage potential. This was revealed from the results of research by a team from the LEMIGAS Oil and Gas Testing Center, Ministry of Energy and Mineral Resources.

“From the LEMIGAS team’s research, data was obtained on the large potential for carbon storage in saline aquifers of 572.77 giga tonnes, then the potential for depleted oil & gas reservoirs of 4.85 giga tonnes,” said the Director General of Oil and Gas, Ministry of Energy and Mineral Resources, Tutuka. Ariadji in Jakarta, quoted Friday, February 23 2024.

This figure is still within the range of research submitted by other institutions. It seems bigger when compared to the results of research conducted by Rystad Energy with a potential of 400 giga tons. And it is still smaller when compared to other institutions’ calculations.

Furthermore, Tutuka explained that this figure was obtained based on research results in 20 producing oil and gas basins in Indonesia, both in saline aquifers and depleted oil and gas reservoirs.

“Of course this data will develop and it will be our concern to continue to update data regarding carbon storage potential,” he added.

Of course, the potential for carbon storage in Indonesia is still very large, considering that currently Indonesia has 128 oil and gas basins, and only 20 basins that have been researched are producing.

“Of the 128 basins, there are still 27 discovery basins and the rest are prospective basins that have not been explored,” said Tutuka.

The potential for carbon storage in the saline aquifer is in the following basins:

1. North East Java Basin amounting to 100.83 giga tons;
2. Tarakan 91.92 giga tons;
3. North Sumatra 53.34 giga tons;
4. Makassar Strait 50.7 giga tonnes;
5. Central Sumatra 43.54 giga tonnes;
6. Kutai 43 giga tonnes;
7. Banggai 40.31 giga tons;
8. South Sumatra 39.69 giga tons;
9. Kendeng 30.64 giga tons;
10. West Natuna 13.15 giga tonnes;
11. Barito 12.05 giga tonnes;
12. Seram 11.58 giga tons;
13. Sand 10.36 giga tons;
14. Salawati 8.75 giga tonnes;
15. West Java 7.22 giga tonnes;
16. Sunda Asri 6.52 giga tons;
17. Sengkang 4.31 giga tonnes;
18. Bintuni 2.13 giga tonnes;
19. North Serayu 1.55 giga tons;
20. Bawean 1.16 giga tonnes.

Along with the issuance of Presidential Regulation Number 14 of 2024 concerning the Implementation of Carbon Capture and Storage Activities, it is possible for cross-border carbon to occur.

Tutuka explained that domestic capacity for carbon storage remains a top priority, accounting for 70% of national carbon storage capacity. Meanwhile, the remaining capacity, or 30%, is intended for cross border carbon.

However, in the cross border carbon scheme, there are conditions that must be met.

“The first thing to do is to have an MoU between countries, or bilateral first, then there is a derivative of Business to Business cooperation. Then it is also regulated that carbon producing emitters who will store their emissions in Indonesia must have investments or be affiliated with investments in Indonesia,” he concluded. (AT Network)
