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

Figure 5

Spatial distribution of geofluid flow and mineral abundance during simulations of different-aperture fracture networks (negative values indicate dissolution and positive precipitation). (a) Plans of reservoir pressure variation at different times; (b) plans of flow rate and temperature variations (length of the arrow representing flow rate, that is, the longer the arrow, the faster the flow rate); (c) changes of abundance of calcite in plans after 10 years; (d) changes of abundance of calcite in plans after 50 years; (e) changes of abundance of calcite in plans after 100 years; (f) changes of abundance of dolomite in plans after 10 years; (h) changes of abundance of dolomite in plans after 50 years; (h) changes of abundance of dolomite in plans after 100 years.
