Acquisition
TGS, provider of energy data and intelligence, announced the acquisition of Apparition Geoservices, securing exclusive access to its proprietary simultaneous source acquisition and separation technology.
Combined with TGS’s Gemini Enhanced Frequency Source (EFS) technology, Apparition creates a platform for step-change improvements in seismic operational efficiency, source capacity, and subsurface imaging clarity.
Apparition is an advanced seismic acquisition and processing methodology that enables multiple sound sources to operate simultaneously in a controlled, coordinated manner.
Unlike traditional dithering approaches, it utilizes precise timing to encode sources distinctly, making overlapping signals easier to separate and process more cleanly.
This increases acquisition efficiency and source capacity while maintaining consistent, high-quality data.
Over the past two years, TGS has tested Apparition across multiple acquisition configurations and marine environments, working closely with the Apparition team and key clients to validate real-world performance.
Testing includes a Hexa Source configuration that delivers unprecedented source efficiency as well as signal-to-noise uplift.
Results demonstrate operational efficiency gains of up to 30%, alongside cleaner signal recovery, improved low-frequency performance, and enhanced visibility of deeper and more complex subsurface targets.
By integrating Apparition into its acquisition and imaging workflows, TGS can deliver scalable multi-source, multi-component seismic programs across ocean bottom node (OBN), towed streamer and Ultra-High Resolution 3D (UHR3D) surveys.
For clients, this translates to improved survey economics, reduced project timelines and greater confidence in exploration and development decisions.
As exploration becomes more complex, the integration of Apparition and Gemini brings together advanced acquisition technology, imaging expertise and global operational scale. The combined solution is designed to accelerate client decision-making and maximize the value of seismic programs.
