QUANTITATIVE INTERPRETATION
Interpretation of amplitudes seismic data can be subdivided into the qualitative and the quantitative.
–        Qualitative interpretation recognizes where seismically detectable change is happening, but it only infers the significance of
those changes. Qualitative changes may be the basis for infill drilling if the inferences are consistent with the rock physics model.
–        Quantitative interpretation attempts to resolve those changes in seismic properties into changes in reservoir properties. Here,
the rock physics model becomes the basis for converting seismic properties to reservoir properties. Ultimately, a quantitative
interpretation might prove the basis for updating the simulation model.
Quantitative Seismic Interpretation works with seismic amplitudes
Quantitative Seismic Interpretation is based how rock physics can be applied to predict reservoir      parameters, such as lithologies
and pore fluids, from seismically derived attributes.
•        Qualitative:
–        based on visual inspection of anomalous or geometric patterns in the seismic reflections
•        Quantitative:
–        uses rock physics modeling to link seismic amplitude with reservoir properties, like, porosity, mineralogy, clay-content, sorting,
grain structure, diagenetic cements etc
