Elnusa advances onshore exploration in Indonesia with new seismic technology investment

Elnusa has expanded its onshore exploration capabilities in Indonesia with a strategic investment in next-generation nodal seismic technology, aimed at improving subsurface imaging and accelerating survey execution across complex geological settings.

The integrated energy services company has acquired 25,000 high-autonomy nodal seismic units along with dual acquisition platforms designed to support both large-scale surveys and smaller, early-stage exploration programs. The technology will be deployed across multiple onshore basins, including projects in Eastern Indonesia early in 2026.

Indonesia’s onshore geology presents significant imaging challenges, including fractured reservoirs, Pre-Tertiary basement targets and deep hydrocarbon systems. According to the company, high-density nodal seismic acquisition offers improved data quality and operational flexibility in remote and logistically constrained environments.

Elnusa said the new systems allow simultaneous survey execution, optimized crew utilization and faster acquisition timelines, while supporting higher-resolution seismic data needed to reduce exploration risk. The technology builds on prior nodal seismic campaigns conducted through leasing arrangements, which demonstrated improved performance in complex terrain.

The company indicated the investment supports its longer-term strategy to strengthen domestic exploration activity and enhance Indonesia’s energy security by improving the efficiency and reliability of onshore seismic programs.
