TGS acquires subsurface imaging specialist Apparition Geoservices

Apparition Geoservices specializes in advanced seismic acquisition and signal processing technology designed to improve subsurface imaging. TGS said that, combining Apparition with its Gemini Enhanced Frequency Source (EFS) technology will “create 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 uses precise timing to encode sources distinctly, making overlapping signals easier to separate and cleaner to process. 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 included a Hexa Source configuration that delivered what TGS described as ’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,” said TGS.

“By integrating Apparition into its acquisition and imaging workflows, TGS can deliver scalable multi-source, multi-component seismic programmes across ocean bottom node, towed streamer and Ultra-High Resolution 3D (UHR3D) surveys,” said the company.

“For clients, this translates to improved survey economics, reduced project timelines and greater confidence in exploration and development decisions.”

TGS executive vice president marine data acquisition Carel Hoojikaas said, “The acquisition of Apparition strengthens our technology portfolio and enhances our ability to deliver measurable value to clients.

“Apparition is central to our multisource and deblending strategy and reflects the direction set out in TGS’ integrated technology roadmap.

“By combining Apparition with our Gemini technology and Ramform fleet, we can increase efficiency, expand source capacity and improve data quality, helping clients reduce project timelines, manage costs and make more confident decisions.”
