Abstract
A method of measuring a rate of mineralization, including: positioning a seismic sensor and/or a harmonic sensor in acoustic communication with a rock formation; injecting carbon dioxide into a borehole in the rock formation; reacting the carbon dioxide with the rock formation to form mineralized carbon dioxide; measuring an acoustic activity generated in the rock formation with the seismic sensor and/or harmonic sensor during the reacting; calculating the rate of mineralization based on the acoustic activity; and adjusting a rate of carbon dioxide injection into the rock formation based on the calculated rate of mineralization.
Claims18
A method of determining a rate of mineralization, comprising:
- positioning a seismic sensor and/or a harmonic sensor in acoustic communication with an igneous or meta-igneous rock formation, wherein the rock formation comprises mafic rocks or ultramafic rocks;
- injecting carbon dioxide dissolved in an aqueous solution into a borehole in the rock formation;
- reacting the carbon dioxide with the rock formation to form mineralized carbon dioxide;
- measuring an acoustic activity generated in the rock formation with the seismic sensor and/or the harmonic sensor during the reacting;
- calculating the rate of mineralization based on the acoustic activity;
- and
- adjusting a rate of carbon dioxide injection into the rock formation based on the calculated rate of mineralization.
