    "patent_abstract": "Provided herein are methods of determining the reactivity of one or more minerals present within a geological formation within a target zone in response to the injection of CO 2 into the target zone. For example, the methods may comprise one or more of the following steps: (1) determining one or more mineral and fluid characteristics of a geological formation comprising one or more minerals; (2) using a reaction rate model to characterize the chemical reactivity of one or more minerals present in a target zone of the geological formation in response to injection of CO 2 into the target zone; (3) using a reactivity index model to estimate the amount of one or more minerals in the target zone that would be modified between a first time point and a second point during a CO 2 injection and sequestration operation; and (4) injecting an amount of CO 2 into the target zone based on the estimated reactivity of the one or more minerals present in the target zone.",
