... respectively and came to the similar conclusion that under acid solution seepage, fracture aperture decreases due to dissolution of minerals at contact points. However, Liu et al. (1997) and Dijk et al. (2000, 2002) found out that apertures of fractures in carbonate reservoir increase under acid solution...

The aperture decreases with increasing the normal stress but increases as the lateral stress rises and obeys an exponential...
