Press Release
        Elnusa Implements SSF Injection at Rokan Working Area to Support
                      Sustainable Oil and Gas Production
Jakarta, June 18, 2025 – PT Elnusa Tbk (ELNUSA), through its subsidiary PT Elnusa Petrofin (EPN), operating under
the energy distribution and logistics goods and services segment, continues to demonstrate its commitment to
strengthening national energy resilience. In collaboration with PT Pertamina (Persero) and PT Pertamina Hulu
Rokan (PHR), EPN has successfully conducted the first phase of Simple Surfactant Flooding (SSF) injection at well
BL-330, Balam Field, within the Rokan Working Area (WK Rokan).

The SSF project is part of a broader Chemical Enhanced Oil Recovery (CEOR) initiative led by PHR aimed at boosting
national oil production. This technology utilizes a low-concentration surfactant specially formulated by the
Technology Innovation Function of PT Pertamina (Persero) under the brand PertaCORE, tailored to the
characteristics of local reservoirs.

President Director of EPN, Doni Indrawan, stated, “This step marks a significant milestone in EPN’s journey to
enhance its CEOR business capabilities. We are fully committed to supporting the advancement of oil and gas
production through technology-based solutions. We believe that innovations such as SSF will serve as key catalysts
in addressing the challenges of national oil and gas production.”

As the commercial arm in this project, EPN is responsible for chemical production, quality control, project
management, and supporting logistics. The synergy also involves Elnusa’s upstream services business unit, which
provides equipment and injection services to ensure optimal execution of field operations. This effort affirms that
collaboration and innovation are essential to overcoming today’s oil and gas production challenges.

Elnusa remains committed to delivering integrated energy service solutions tailored to the needs of the national
energy industry. By prioritizing innovation, operational reliability, and strategic collaboration, Elnusa is ready to
support the sustainable growth of domestic energy production. This initiative forms part of Elnusa’s tangible
