Injection of CO2 to rock formation can also have a negative impact on porosity and permeability of porous medium because grain displacement, compaction, and shrinkage-swelling and thermochemical processes such as precipitation of minerals and asphaltenes, and hydrate formation. In the research we will fill the gap in the knowledge about length (distance), magnitude, and velocity of capillary-driven backflow, viscous forces under different thermodynamic, continuity of water film conditions, the impact of salinity and salt type on the magnitude, distribution, and precipitation pattern, nucleation and growth crystals. As a result we would give an answer on how strong is an effect of CO2 injectivity to induced salt precipitation.
