Productivity, injectivity, and sweep efficiency enhancement

A method of enhancing productivity of a subterranean wellbore, the method comprising:

• introducing a carbonated mixture comprising water and carbonate anions to a target zone of the subterranean wellbore;
• introducing basaltic particles to the target zone of the subterranean wellbore;
• contacting the basaltic particles with the carbonated mixture;
• dissolving at least a part of the basaltic particles with the carbonated mixture to release divalent cations including calcium cations, magnesium cations and ferrous cations;
• reacting, in the target zone of the subterranean wellbore, the divalent cations with the carbonate anions in the carbonated mixture to produce carbonate minerals;
• providing stimulus to the basaltic particles and the carbonated mixture to promote the dissolving and the reacting;
• depositing at least a part of the carbonate minerals to fractures of the target zone;
• monitoring the reacting of the divalent cations with the carbonated anions and depositing;
• and
• optionally repeating one or more of the introducing the basaltic particles, the introducing the carbonated mixture, the dissolving, the reacting, the providing the stimulus, the depositing, and the monitoring,
• wherein the carbonate anions are formed by dissolving carbon dioxide in water,
• wherein the stimulus comprises at least one of infrasonic wave, acoustic wave, ultrasonic wave, and microwave.
