Salt-out in porosity medium: Mitigating gas channeling using alcohol-induced salt precipitation

In this paper, the microscopic structure of NaCl crystal grain, distribution of grain size were analyzed by means of SEM, grain size analysis units analyzed by laser particle analyzer. Compared water-gas alternation injection (WGA) and foam injection, the alcohol-induced salt precipitation has some advantages with mitigating gas channeling in gas condensate field which more economic, more efficient and persistence.
