This study summarizes the findings of a hydrodynamic investigation of the Basal Colorado to Mississippian section and determines the relationship between oil quality, hydrodynamics and stratigraphy. The results of the study indicate that due to a general increase in head with stratigraphic depth and the scatter of data points on PE plots, it can be assumed that there is a continuous flowing system. Oil analyses indicate an oil density near that of formation water, therefore, any traps would have to have significant closure in the flow direction to enable oil to be structurally trapped. Effective trapping most likely requires a stratigraphic component. In addition, oil gravity data suggests that there is a degradation of oil quality due to the dynamic flow of the system in the Lower Mannville.
