Project Summary

Monitoring changes in geophysical rock properties – their density, electrical conductivity, and seismic properties – are a key method for understanding movement of injected CO2 plumes. Mathematical and statistical analysis (an inversion) of geophysical data helps researchers create a model of injected CO2 movement. However, such a model is limited when it is only from one data set. A joint inversion of several differing geophysical data sets – such as time lapse seismic and electromagnetic (EM) data  and density from borehole gravity – can help create a more complete  model of plume movement.

This two-year project will apply joint inversion of geophysical data for the Aquistore CO2 sequestration monitoring project. Researchers will jointly invert gravity, seismic and EM data.
