Elnusa optimises upstream oil and gas assets to strengthen national energy security
PT Elnusa Tbk (ELSA), a subsidiary of PT Pertamina (Persero)’s upstream subholding, is driving increased production and operational efficiency in the upstream oil and gas sector as part of efforts to further strengthen national energy security.
The optimisation of upstream oil and gas assets is being carried out through the integration of technology, engineering, operational services, and chemical solutions capabilities.
“The target of increasing national oil production requires orchestration of all capabilities within the upstream ecosystem. Elnusa is taking a role through the integration of technology, competence, and operational execution so that every solution we present can provide measurable contributions to improving asset productivity,” said ELSA Corporate Secretary Rustam Aji in an official statement in Jakarta on Wednesday.
Rustam said the company sees this opportunity not merely as business development, but as part of its contribution to the national energy security agenda.
He continued that strengthening these capabilities is in line with the company’s role as an integrated energy services company with competencies in integrated upstream oil and gas services, energy distribution and logistics, as well as oil and gas supporting services.
“Cross-capability integration enables the company to capture broader business opportunities while strengthening its contribution to Pertamina’s strategic needs,” Rustam said.
One of the strategic capabilities is carried out through its subsidiary, PT Elnusa Petrofin, which develops integrated chemical services including specialty chemicals, drilling fluid, and enhanced oil recovery (EOR).
“Elnusa does not only act as a provider of supporting materials, but is developing as part of the solution to maintain production performance, flow assurance, asset integrity, and optimisation of oil productivity,” Rustam said.
Within the Pertamina Group ecosystem, Rustam explained that the company collaborates with Pertamina Technology & Innovation (TI) in the development and implementation of chemical solutions for enhanced oil recovery, bringing together research and technology development capabilities with implementation, engineering, and operational capabilities in the field.
“This collaboration is also part of the journey of developing chemical enhanced oil recovery (CEOR) solutions, including the CEOR Rama Project which will be implemented on 8 July 2026,” Rustam said.
Meanwhile, the company’s Integrated Chemical Services portfolio includes fluid separation, flow assurance, asset integrity assurance, water treatment, drilling fluid, and EOR.
Rustam explained that these capabilities have been applied to various upstream assets of the Pertamina Group in Regions 1, 2, and 3, such as Pertamina Hulu Rokan, Pertamina EP, and Pertamina Hulu Mahakam, and are further strengthened by the development of specialty chemicals and increased local content, thereby opening greater value creation opportunities for the upstream ecosystem.
Rustam said that Elnusa’s optimisation of upstream oil and gas assets is in line with the government’s agenda to increase national oil production to 1 million barrels per day by 2030.
The Ministry of Energy and Mineral Resources has emphasised that achieving this target requires production optimisation through technology, reactivation of idle wells, and development of new oil and gas potential. Enhanced Oil Recovery is one of the technologies being promoted to increase oil recovery from fields that are already in production.
