Title:
METHOD OF GEOLOGIC STORAGE OF CARBON DIOXIDE, METHOD OF DEVELOPING CARBON DIOXIDE-CONTAINING NATURAL GAS FIELDS, AND METHOD OF OCEAN WATER STORAGE OF CARBON DIOXIDE
Document Type and Number:
WIPO Patent Application WO/2022/201424
Kind Code:
A1
Abstract:
This method of geologic storage of carbon dioxide generates carbon dioxide supersaturated water (4) by the dispersion of nanometer-size microbubbles of a carbon dioxide fluid, and injects the microbubble-containing carbon dioxide supersaturated water into the stratum water (2) in a geologic layer (1). At that time, by adjusting the particle size and dispersion amount of the microbubbles in the carbon dioxide supersaturated water, a sinking current (6) of the microbubble-containing carbon dioxide supersaturated water is formed in the stratum water. In this way, geologic storage of carbon dioxide can be performed regardless of an upper seal (a sealing layer).
