Mineral Filling Pattern in Complex Fracture System of Carbonate Reservoirs: Implications from Geochemical Modeling of Water-Rock Interaction

Figure 9

Spatial distribution of mineral abundance for prescribed fracture patterns after simulations. (a) Changes of calcite abundance in cross section of Pattern 1 (net-shaped fractures) during fluid injection; (b) changes of calcite abundance in cross section of Pattern 2 (variable aperture); (c) changes of calcite abundance in cross section of Pattern 3 (variable angle); (d) changes of calcite abundance in cross section of Pattern 4 (variable connectivity).
