Sandia National Laboratories is a federally funded research facility operated by Sandia Corporation for the Department of Energy. The presentation discusses research on fluid flow through rock salt. It summarizes the theory of how pore networks evolve in ductile rocks under pressure and temperature. Laboratory experiments on rock salt samples show that pore connectivity and fluid percolation depend on porosity and dihedral angle as predicted by the theory. Comparison to field data from hydrocarbon wells in salt formations shows generally good agreement between observations and the theoretical model.
