Press Release
    Supporting National Energy Resilience, Elnusa Completes
                  Lisaman 3D Seismic Survey
Jakarta, 12 March 2025 – PT Elnusa Tbk (Elnusa, IDX: ELSA), a subsidiary of PT Pertamina Hulu Energi (PHE) under Pertamina’s
Upstream Subholding, has successfully completed the Lisaman 3D Seismic Survey Project in Riau Province. The six-month
project covered three regencies: Kampar, Siak, and Bengkalis.

The Lisaman 3D Seismic Survey was conducted to obtain more accurate geological data to identify potential oil and gas
reserves in the region. Spanning a survey area of 358 km² with a total of 20,332 shot points, this project represents a strategic
step in supporting exploration and national energy development.

Vice President of Exploration Technical Excellence & Coordination at PT Pertamina Hulu Energi, Ahmad Najihal Amal,
expressed his appreciation for the project's success, stating,
"The successful completion of the Lisaman 3D seismic survey is a significant achievement in exploration efforts. The data
obtained will serve as a foundation for further exploration steps to support national energy resilience."

Meanwhile, Director of Operations at PT Elnusa Tbk, Endro Hartanto, emphasized that this success was largely due to the
utilization of cutting-edge 3D seismic technology.
"With 3D seismic technology, we can identify subsurface geological structures with high accuracy. The data acquired from
this survey will assist in planning more precise and efficient exploration activities," said Endro.

As part of its commitment to sustainable industry practices, Elnusa ensured that the entire seismic survey process complied
with environmental regulations. These measures were taken to minimize ecological impact and promote responsible natural
resource management.

This project also recorded several notable achievements, including 839,472 total safety manhours and the completion of
operations 30 days ahead of the initial target.

Elnusa’s strategic initiative aligns with President Prabowo Subianto’s Asta Cita in the energy sector, which emphasizes energy
security and self-sufficiency through innovation and advanced technology utilization. Elnusa remains committed to delivering
top-tier energy services that drive the growth of Indonesia’s upstream oil and gas sector.
