... by referring to the paper published by Leontaritis and Mansoori 1 , 2 Studies have shown that the complexity of asphaltene itself vastly contributes to the anomalous behavior of this fraction of the crude oil. Hitherto, "why", "how" and "when" asphaltene will flocculate and precipitate in the production...

... the reservoir permeability profile by chemical precipitation. This method employs water soluble salts of earth alkali group that react with CO 2 to form carbonate precipitate. Chemical precipitation occurs in the high permeability zones and the subsequent fluid flow will be diverted to unswept portion...

... the tendency of CO 2 to bypass the residual oil would be to plug the large pores by forming solid materials in the individual pore spaces through in situ chemical precipitation. Several relatively inexpensive salts of the alkali earth group that are soluble in water react with CO 2 to form solid carbonates...
