Time-lapse analysis is not commonly done for carbonate pools because the dry bulk modulus of the carbonate matrix is very high. The high dry bulk modulus dominates the rock strength and the low modulus of the fluids within the pore space and, therefore, the high bulk modulus masks the effects of fluid changes. Thus, the fluid effects seen in seismic data after gas injection are small and difficult to detect in carbonate reservoirs.
