Gemini X: Encoded for more.
Engineered for better imaging.
Gemini X combines Gemini's enhanced frequency performance with structured multi-source encoding and precision signal recovery, significantly increasing source productivity while optimizing data quality.
More sources. Sharper imaging. Greater efficiency.
Gemini X combines TGS' industry-leading Gemini source technology with Apparition, TGS' proprietary encoded acquisition and source separation capability. Built to support coordinated multi-source operations, Gemini X increases acquisition productivity while maintaining the signal quality modern imaging workflows demand. The result: better data, greater operational flexibility, and a scalable acquisition solution built for increasingly ambitious exploration objectives.
Designed around the needs of today's imaging and inversion workflows, Gemini X helps operators move from acquisition to subsurface understanding with greater confidence and efficiency.
Expanding What’s Possible
with Gemini X
Gemini X enables operators to pursue acquisition strategies centered on imaging objectives rather than traditional operational limitations. Combining extended low-frequency performance with structured multi-source encoding and precision signal recovery, Gemini X delivers the data quality advanced imaging needs while increasing operational productivity.
The result is access to richer datasets, improved subsurface illumination, and acquisition programs capable of supporting the most demanding exploration and development challenges, including basins where OBN has historically been cost-prohibitive.

How it Works
Gemini X combines Gemini's extended-frequency source technology with advanced encoded acquisition and precision signal recovery. Multiple sources operate in a structured, encoded firing sequence. During processing, source signals are accurately separated and recovered, preserving the data quality required for advanced imaging workflows.
The combination of enhanced-frequency source energy, scalable multi-source acquisition, and precision signal recovery enables more productive survey execution while delivering datasets optimized for modern imaging, inversion, and earth-model-building workflows.
Gemini X is built on a commercially deployed, client-validated foundation, extended with proprietary Apparition technology and backed by decades of TGS geoscience, high-performance computing, and delivery expertise. It's TGS technology, run by TGS people, from acquisition through to the final earth model.
Results in Action
Don’t take our word for it. Gemini EFS has been tested in the field with results that speak for themselves.

Expanding the reach of OBN
In July 2026, TGS announced a strategic collaboration with Allton, granting exclusive access to next-generation node deployment and recovery technology. Paired with Gemini X's source-side efficiency gains, this addresses both sides of the OBN cost equation - acquisition and node handling - to bring exploration-scale OBN to basins where it was previously out of reach.
Built on TGS' Integrated Solutions Capabilities
TGS is the only company in the seismic industry to offer acquisition project design, marine data acquisition, multi-client subsurface data and seismic imaging as a single, fully integrated solution. Gemini is the technological foundation that makes that integration worth more than the sum of its parts, and Gemini X extends that foundation.
Gemini X isn't a standalone acquisition upgrade. It's designed to work with the rest of the imaging stack (OBN, GeoStreamer, E-DMFWI, 4D and AI/ML-accelerated workflows), so gains at the point of acquisition compound all the way through to the earth model and the decisions built on it.
