A deposition-consistent connection between lithology, porosity and fluid, combined with a model that relates these variables to the elastic properties which allows for lithology substitution is presented. A crucial element of lithology substitution is a link between sediment properties and conditions like porosity, shale content and saturation, that honors the rules of geology and deposition. Once the mineralogy, porosity and pore fluid are known, RC model is used to calculate the elastic properties in the pseudowell generated from the original well by lithology substitution. The results as illustrated by the synthetic AVO curves show that use of offset data should be instrumental in delineating reservoir sand.
