[[file:pressure-detection_fig1.png|300px|thumb|{{figure number|1}}Schematic diagram showing the location of abnormal pressures in southern Louisiana. The continental and deltaic facies contains sandy beds. The nerltic (nearshore) facles contains a few silty and sandy beds that connect laterally to the deltaic facies. The outer shelf facies contains almost no sandy beds, and the pore fluids cannot escape. The growth faults are seals that stop the lateral flow of pore water toward the neritic facies.<ref name=pt03r13>Dickey, P. A., Shriram, C. R., Paine, W.
