Quantitative prediction of injected CO2 at Sleipner using wave-equation based AVO", wave-equation based amplitude-versus-offset inversion is a fundamentally new approach towards converting seismic pre-stack data into elastic subsurface properties. By solving the full elastic wave-equation, the routinely made assumption of a linear relationship between seismic amplitudes and reservoir properties is overcome. As a consequence, interbed multiples, mode conversions and transmission effects over the inversion interval are properly accounted for. Additionally, the method directly solves for compressibility and shear compliance, which are approximately three times more sensitive to fluid and lithology changes when compared to impedances. This makes the technology suitable for quantitative interpretation even in geologically highly complex scenarios. In this e-Lecture, a high-level introduction to wave-equation based AVO inversion will be given and an application to the Sleipner Carbon Capture and Storage (CCS) project will be presented.
