There is a great contrast in geochemical and hydrogeologic estimates of the residence times of pore fluids in sedimentary basins. This contrast is particularly evident in the Alberta Basin, Canada, which has served as the study area for important studies of long‐term fluid flow and transport. To address these differences, we developed two‐dimensional simulations of groundwater age, constrained by...
Cation and anion concentrations and oxygen and hydrogen isotopic ratios of brines in the Asmari Formation (Oligocene–early Miocene) from the Marun oil field of southwest Iran were measured to identify the origin of these brines (e.g. salt dissolution vs. seawater evaporation) as well as the involvement of water–rock reaction processes in their evolution. Marun brines are characterized by having higher...
Abstract Numerical simulations show that water and oil/oily-contaminant migration are controlled by regional fluid-potential fields which may be modified locally by highly permeable lenses and buoyancy. In addition, fluid potentials are coupled to the distribution of oil/oily-contaminant via relative permeability and capillary-pressure curves. As saturation distributions evolve through space and time,...
