Carbon Capture and Sequestration (CCS) Monitoring

We determine wide-area surface movements related to CO2 injection. 
Ground responses are constantly monitored to determine fluid migration and ensure that injection strategies remain cost-effective.

TRE provides long-term, cost-effective remote sensing techniques to combat the challenges associated with gas storage sequestration. 

Accurate and repeatable ground surface measurements are also incorporated into subsurface models to determine CO2 plume migration. Using complementary ground-based data, pressure models of the subsurface are created in order to verify reservoir integrity and monitor unexpected migrations.

The integration with 3D seismic surveys has revealed interesting trends and insights into structures present at the In Salah field (see figure below), which may be controlling the movement of CO2 in the subsurface. Initial observations indicate that deep seated (below reservoir) faults may control the field structure at the Carboniferous injection level. Detailed analyses of the satellite images, and their correlation with the seismic data, confirms this interpretation of the probable CO2 movement controlling mechanism.
