Several researchers have suggested that upward and lateral hydrothermal fluid flows were responsible for the dolomitization of various Devonian and Mississippian reservoirs in the Western Canada Sedimentary Basin, based on sedimentological, geochemical and diagenetic evidence. In this study, numerical simulation was applied to investigate hydrothermal fluid flow in the Wabamun Group, Parkland field, NE. B.C., Canada. Numerical results indicate that faults play a critical role in controlling hydrothermal fluid flow. Faults provide fluid pathways connecting the basement of the basin with the overlying sedimentary layers. Upwelling fluid flow via faults brings reactants and heat from underlying strata to shallow formations for diagenetic reactions (e.g. dolomitization and/or chertification) or forming ore deposits. Fault properties, such as permeability, dip angle and depth of penetration, control the hydrothermal fluid flow patterns and magnitudes. The salinity distribution of formation water, permeability configuration of host rock, regional heat regime and regional fluid flow are also important factors affecting hot and brine fluid flow and accompanying heat and mass distribution. High salinity fluids in problem domain restrict the upwelling of hot fluid flow driven by buoyancy force. If the salinity of fluids in the modeled domain is high enough, and the resulting brine gravity is strong enough, the cold seawater will enter the system via faults mixing with the ascending hot brines along the faults from the deep basin.Dept. of Earth Sciences.
