UTILISATION & STORAGE
IMAGING SUBSURFACE FORMATIONS
Greenhouse CO2 emissions are collected from the Earth’s atmosphere and stored in geological formations underground—in depleted oil and gas reservoirs, deep saline aquifers or inactive coal beds. Once the gas is compressed into liquid form and pumped into a storage facility, it needs to be monitored to ensure that the CO2 remains in place and does not leak toward the surface.
MONITORING STORED CO2
Norway has been sequestering carbon dioxide in this fashion for more than 20 years, but has been limited in its ability to monitor its CO2 storage area by the practical difficulties involved in producing marine seismic images.
Precision Impulse seismic sources remain permanently deployed on land or the ocean bottom, thus enabling operators to collect images of the subsurface formation as frequently as necessary to visualize any and all movement of CO2 in the storage facility.
