Salt plugging of the prolific Buntsandstein reservoir has been the reason for failure for many wells in the salt-diapir prone areas of the Southern North Sea. In the past, as no methods existed that could account for shear forces when substituting pore-content between solids and fluids, qualitative approaches have been used based on careful interpretation, visual and neural-network wave-form analysis and classification, or amplitude-based assessments. Typically these studies were focussed on the Top Volpriehausen reflector only. However, these approaches have proven to be vulnerable to interpretation errors, or spurious amplitude results. With the development of pore-content substitution approaches based on extensions of the Gassmann equation (Ciz and Shapiro, 2008), one can cater for the presence or absence of shear forces in the pore content due to solid (i.e. salt) infill.
