Press Release
  Elnusa Strengthens Indonesia’s Oil and Gas Exploration Through the Successful Completion of the
                   Kandawulo 3D Offshore Seismic Survey in the Makassar Strait
Jakarta, 29 July 2026 – PT Elnusa Tbk (IDX: ELSA), an integrated energy services company and part of Pertamina's Upstream Subholding, has reaffirmed its commitment to
supporting Indonesia’s energy security through the successful completion of the Kandawulo 3D Offshore Seismic Survey in the waters of the Makassar Strait, Mamuju Regency,
West Sulawesi Province. Covering an area of 2,500 km², the survey was originally scheduled for completion within 76 days. Through efficient and optimized operational
execution, Elnusa successfully completed the data acquisition in just 56 days, finishing 20 days ahead of schedule. The project also achieved 99,120 safe man -hours with zero
recordable accidents, underscoring Elnusa’s strong operational excellence and commitment to safety.

As a national energy services company with integrated geoscience capabilities, Elnusa plays a vital role in providing subsurface data that serves as the foundation for oil and gas
exploration. Its capabilities extend beyond seismic data acquisition to include seismic data processing using the Pre Stack Time Migration (PSTM) method, which will be carried
out over approximately six months following the completion of data acquisition. This integrated capability further strengthens Elnusa’s position as a comprehensive geoscience
service provider, delivering end-to-end solutions to support Indonesia’s oil and gas exploration activities.

Throughout the execution of the Kandawulo 3D Offshore Seismic Survey, Elnusa ensured that every stage of the operation adhered to the principles of Health, Safety, Security,
and Environment (HSSE), environmental protection, and full compliance with all applicable regulations. This disciplined operational approach was one of the key factors enabling
the project to be completed ahead of schedule while maintaining 99,120 safe man-hours with zero workplace accidents.

PT Elnusa Tbk’s Operations Director, Andri Haribowo, stated that seismic surveys represent one of the most critical stages in the upstream oil and gas value chain, as they
generate subsurface data that forms the basis for exploration decision-making. “Completing the data acquisition 20 days ahead of schedule while maintaining 99,120 safe man-
hours demonstrates that productivity, work quality, and operational safety can go hand in hand through the disciplined implem entation of operational standards. This
achievement reflects Elnusa’s operational excellence in delivering reliable geoscience services, supported by advanced technology, highly competent human resources, and a
strong HSSE culture. Moving forward, we will continue to strengthen our geoscience capabilities and service innovations to support increased exploration activities and
contribute to sustainable energy security in Indonesia,” said Andri.

Andri further emphasized that the success of the operation was also made possible through close collaboration between Elnusa and various stakeholders. Intensive coordination
with the West Sulawesi Provincial Government, Mamuju Regency Government, the Indonesian National Armed Forces (TNI), the Indonesian National Police (Polri), the
Harbormaster Office, and other relevant authorities played a significant role in ensuring smooth operations and full compliance with applicable regulations.

In addition, Elnusa maintained open and transparent communication with local communities, particularly fishermen in Mamuju Regency. By providing information on project
phases, operational areas, and survey mechanisms, Elnusa sought to build mutual understanding so that exploration activities could be carried out in harmony with the
livelihoods of coastal communities.

With more than five decades of experience in delivering geoscience services, onshore and offshore seismic surveys, drilling, and various oilfield services, Elnusa has established
a strong foundation for providing integrated upstream oil and gas solutions. Supported by robust operational capabilities, highly skilled professionals, and the implementation
of good corporate governance, Elnusa continues to strengthen its position as a strategic partner to the upstream oil and gas industry in supporting successful exploration, field
development, and Indonesia’s national energy security.

The successful completion of the Kandawulo 3D Offshore Seismic Survey further reinforces Elnusa’s position as a strategic partner to Indonesia’s upstream oil and gas industry
in delivering integrated geoscience services. Looking ahead, Elnusa will continue to advance its service innovations and operational capabilities to support increased exploration
activities and contribute to a more sustainable and resilient national energy future.
