摘要
Methods for long-term gravimetric monitoring of carbon dioxide stored in a geological formation are disclosed. In some embodiments, the methods include the following: joining gravimetric sensors with sidewalls of boreholes in the geological formation at various vertical depths; using the gravimetric sensors, measuring a local gravitational field or a gravity gradient at a first time to develop baseline gravimetric data; reading and transmitting the baseline gravimetric data to a data recording device exterior to the boreholes; using the gravimetric sensors, measuring a local gravitational field or a gravity gradient after the first time to develop post-baseline gravimetric data; reading and; transmitting the post-baseline gravimetric data to the data recording device; and quantifying the carbon dioxide stored in the geological formation by comparing the baseline gravimetric data to the post-baseline gravimetric data to determine both vertical and horizontal positioning of the carbon dioxide stored in the geological formation.
