Vaporisation of water during dry CO2injection can cause salt precipitation and lead to significant reduction in injectivity. Research described in this paper aimed at improving the understanding of the halite scaling process through experimental and numerical investigations. Experimental results indicated porosity reductions of about 3 - 5 % and permeability reduction between 13 to 75 %. Numerical simulation results have shown that halite scaling can have a significant impact on field operations. They also suggested that, salt precipitation can occur at the caprock interface increasing the sealing capacity around the wellbore. © 2013 The Author.
