Hydrologic behavior of Cretaceous Shales

The nature of groundwater flow in low permeability settings is poorly understood due to (1) historic inattention to non- aquifer/reservoir rock units and (2) inherent difficulties, related to time and size scales, of observing the phenomena of interest. Nonetheless, low-permeability units are of great importance because they mediate aquifer/reservoir behavior, have important roles in the evolution of hydrologic systems and geologic processes over geologic time and can confine toxic materials for long periods. Cretaceous shales in the midcontinent offer the opportunity of studying, at relatively accessible depths, thick and extensive bodies of low-permeability media. Objectives of this project are to develop, through theoretical studies coupled with study of the flow systems in midcontinental Cretaceous shales, a better understanding of the significant flow processes in low-permeability environments. This information can then be exploited to extract information about flow history retained in the current conditions because of long response times and also will permit long-term prediction of flow behavior.
