Carbon dioxide storage assessment methods comprise the suite of analytical, numerical, and empirical approaches used to estimate the capacity, injectivity, containment security, and long‑term behavior of CO₂ in geological storage formations. They typically include basin- and site-scale static volumetric calculations, dynamic reservoir simulation of multiphase flow and geochemical interactions, pressure and stress modeling for caprock integrity, and probabilistic or scenario-based uncertainty analyses. These methods integrate geological, petrophysical, geomechanical, and geochemical data to quantify technically and economically usable storage resources, evaluate risks such as leakage or induced seismicity, and support screening, site selection, and regulatory decision-making for carbon capture and storage projects.
Sixty-million-year-old rock samples from deep under the ocean have revealed how huge amounts of carbon dioxide are stored for millennia in piles of lava rubble that accumulate on the seafloor.
