Mark Sams presents various opportunities to use rock physics to improve the quality and consistency of seismic petrophysics in the context of a seismic reservoir characterisation study. The particular method employed will depend on the quality of the measured elastic logs and the confidence in the rock physics model established. One area, not discussed here, where confidence in the rock physics model may be difficult to establish is when hydrocarbons are present. The uncertainty in how the logs respond to hydrocarbons, especially when invasion has taken place, is often quite high. Despite such uncertainties integrating petrophysics and rock physics has significant advantages.
