Abstract
Summary
We combine gravity and CSEM data acquired at the Sleipner field in order to estimate the actual thickness and in situ resistivity of the CO2 plume when the CSEM data was collected in 2008. For the sake of simplicity, we assume the CO2 plume as a homogeneous elliptical cylinder, and apply the physical properties of the CO2 plume from literature review. The result is within a range of our expectation. Through this exercise, we can see the feasibility of combining the CSEM and gravity data to improve the time-lapse interpretation for monitoring CO2 storage sites, as complementary to time-lapse seismic data.
