A Diverse Approach to CO2 Monitoring Solutions

TGS, with help from key partners, continues to invest in concepts and technologies to enable safe, efficient, and cost-effective monitoring for Carbon Capture and Storage (CCS) sites.

TGS Versatile Acquisition Solutions

Bringing Cutting-Edge Seismic Acquisition to CCS

TGS is actively testing a variety of cost-effective seismic acquisition and node-based technologies to enhance subsurface imaging efficiencies compared to current conventional streamer-based 4D seismic acquisition.

Our XHR (Extended High-Resolution) imaging technology can provide 4D imaging for Carbon Storage sites for initial site identification and ongoing 4D monitoring.

Our ocean bottom node (OBN)-based solutions can also be used to provide innovative and cost-effective solutions to monitor carbon storage reservoirs.

DAS / VSP: Leveraging Fiber Optic Technology

TGS provides a cost-effective 4D CO2 “in well” fiber optic monitoring solution with Distributed Acoustic Sensing (DAS) and active sources to produce Vertical Seismic Profiles (VSP). This technology leverages existing fiber technologies and a step change in imaging technology, creating an image over much broader areas than conventional DAS (VSP) data for active source applications.

As a passive sensor, the fiber captures additional data, including temperature and pressure, resulting in a real-time monitoring solution. In some cases, feasibility modeling has revealed that a DAS (VSP) dataset can cover the 4D needs for the injected CO2 plume for two decades or more, reducing the cost of the overall monitoring program.
