... of the leaking fluid in the defect includes the overall local concentration of each component and the phase volume fractions. The chemical reaction-transport phenomenon which takes place within the cement matrix has recently been widely studied, through numerical and lab experiments (see for example ( Duguid...

... conditions CO 2 is often in a near critical or supercritical state. Moreover CO 2 at certain pressure and concentration range is capable of forming second liquid hydrocarbon phase ( LaForce 2005 , Lee, et al. 1988 , Orr, et al. 1981 ). Formation of the forth phase brings in a question of multi...

... steady-state between CO 2 in the reservoir and in the caprock. We find that in this case, the aqueous CO 2 concentration would differ little from the reservoir and would be expected to produce carbonation reaction fronts in cements that are relatively uniform as a function of depth. cement...
