ObjectivesThis multidisciplinary study is designed to provide improvements in advanced reservoir characterization techniques. This goal is to be accomplished through 1.
2.
3.
4.An examination of the spatial variation and anisotropy of relative permeability in the Tensleep Sandstone reservoirs of Wyoming;The placement of that variation and anisotropy into paleogeographic, depositional, and diagenetic frameworks;The development of pore-system imagery techniques for the calculation of relative permeability; and Reservoir simulations testing the impact of relative permeability anisotropy and spatial variation on Tensleep Sandstone reservoir enhanced oil recovery.Concurrent efforts are aimed at understanding the spatial and dynamic alteration in sandstone reservoirs that is caused by rock-fluid interaction during COz-enhanced oil recovery processes. This work focuses on quantifying the relationship of fluid-rock interaction with lithologic characterization (in term of changes in relative permeability, wettability, and pore structure) and with fluid characterization (in terms of changes in chemical composition and fluid properties.) This work will establish new criteria for the susceptibility of Tensleep Sandstone reservoirs to production-induced formation alteration that results in change in relative permeability and in wellbore scale damage.2. Examination of regional trends in water chemistry;3. Examination of local water chemistry trends at field scale; and 4. Chemical modeling of both the reservoir and experimental systems in order to scaleup the experiments to reservoir conditions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
