Since geological sequestration of carbon dioxide has the potential to induce seismicity, researchers have developed methods to monitor and model the risk of injection-induced seismicity, in order to better manage the risks associated with this phenomenon. Monitoring can be conducted with measurements from an instrument like a geophone to measure the movement of the ground. Generally a network of instruments around the site of injection is used, though many current carbon dioxide injection sites do not utilize any monitoring devices. Modeling is an important technique for assessing the potential for induced seismicity, and there are two primary types of models used: physical and numerical. Physical models use measurements from the early stages of a project to forecast how the project will behave once more carbon dioxide is injected, and numerical models use numerical methods to simulate the physics of what is occurring inside the reservoir. Both modeling and monitoring are useful tools to quantify, and thus better understand and mitigate the risks associated with injection-induced seismicity.
