Testing the correlation between seismic stratigraphy, diagenesis and physical rock properties: Evaluation of fluid flow during early and late diagenesis. Progress report, April 15, 1994--April 14, 1995
This project, being conducted in collaboration with G. Eberli and P. Swart of the University of Miami, is designed to test the conceptual models of diagenesis developed by those researchers with numerical modeling of fluid through the Great Bahama Bank. The finite difference code HST3D is being used to simulate fluid flow, heat transport and solute transport through the Great Bahama Bank. Initial simulations are focussed on a 2-D profile for which the major hydrologic units and properties were chosen based on available seismic and core data provided by Miami collaborators. The model is being used to assess the sensitivity of flow patterns and flow rates to variations in hydraulic, thermal and density gradients and boundary conditions. The numerical model will also be used to study the effects of sea level fluctuations and changes in permeability due to diagenesis. This will involve modification of the boundary conditions and permeability distribution to reflect conditions that are inferred to have existed during earlier diagenetic periods or as a result of sea level change.
