Can 4D seismics be used to quantify the volume of geologically sequestered CO2? (original) (raw)

This research investigates the application of 4D seismic imaging techniques to accurately quantify the volume of carbon dioxide (CO2) sequestered in geological formations, an essential aspect for the certification and financial viability of carbon capture and storage (CCS) technologies. The study consists of a detailed modeling approach that integrates reservoir fluid-flow, rock physics, and seismic forward modeling to create synthetic seismic data. It evaluates the conventional workflows for estimating stored CO2 volumes and assesses the implications for certification processes of carbon credits. By providing a scientific framework for improving the accuracy of seismic estimations, this work aims to enhance regulatory practices surrounding CCS.
