Figure 4

Simulation results for the illustrative sedimentary basin simulation. (a) and (b) Spatial distribution of point pressure heads at 20,000 years, and its temporal evolution at observation points located in a sandstone aquifer (Sand2, observation point located at 2,800 m depth) and in a shale aquitard (Sh1, observation point located at 2,300 m depth). (c) and (d) Spatial distribution of density at 20,000 years, and its temporal evolution at observation point located in sandstone aquifer (Sand4 observation point located at 300 m depth). (e) and (f) Spatial distribution of temperature at 20,000 years, and its temporal evolution at observation points located in sandstone aquifer (Sand1, depths indicated on figure).
