Kangean Energy to Conduct 3D Seismic Survey in East Java; SKK Migas Emphasizes Subsurface Data as Pillar of National Energy Security

Nov 26, 2025


Kangean Energy Indonesia (KEI) is set to begin a large-scale 3D seismic survey in the Kangean Islands, East Java, after fulfilling all required permitting procedures, including environmental and social compliance assessments. The confirmation was issued by the Jawa-Bali-Nusa Tenggara (Jabanusa) Regional Office of the Special Task Force for Upstream Oil and Gas, SKK Migas, marking the survey as one of the key upstream exploration efforts in the region. 

Anggono Mahendrawan, Head of SKK Migas Jabanusa, stated that seismic acquisition plays a crucial role in determining the direction of Indonesia’s oil and gas exploration activities. According to him, subsurface geological data generated from seismic imaging is essential not only for contractors but also for the government in preparing long-term resource planning. “This seismic survey is actually a national necessity. We need geological layer data to support exploration activities and secure future energy resources,” Anggono said during a discussion with ruangenergi.com in Jakarta on Monday, 3 November 2025. 

The survey will produce highly detailed information regarding the structure, depth, and lithology of underground rock formations. SKK Migas emphasized that such data is a critical determinant in assessing hydrocarbon potential in a given area and will be incorporated into the national upstream exploration database. The data will serve as the technical basis for decision-making on subsequent drilling plans, investment prioritization, and future working area allocations. 

Anggono acknowledged that upstream exploration remains a high-risk investment for contractors due to the uncertainty of commercial discoveries. However, he underlined that seismic datasets retain long-term value for the country regardless of discovery outcomes. “If no reserves are found, the cost won’t be recovered, but the data will still be beneficial for future energy development,” he noted, referring to the seismic data retention system that supports the national exploration master plan. 

SKK Migas also highlighted that the 3D seismic activity by KEI requires substantial investment and has undergone rigorous environmental and social impact verification. The agency stressed that adherence to regulatory and community safeguards is a prerequisite for the sustainability of upstream operations, especially in offshore and remote island clusters such as the Kangean region. 

Beyond its technical purpose, the survey is aligned with SKK Migas’ broader strategy to increase exploration intensity across frontier and underexplored basins in support of the national one-million-barrels-per-day oil production target. Strengthening the national subsurface data inventory is considered crucial to attracting upstream investors, reducing geological uncertainty, and enhancing resilience in domestic energy supply. 

Further updates on survey progress, including data acquisition scope, timeline for processing and interpretation, and follow-up drilling plans are expected to be announced after the initial operational phase in the coming months.
