Abstract
Summary
In the context of seismic reservoir characterisation the availability of high quality and consistent petrophysical analysis is essential. Achieving consistency is often compromised by poor data quality, lack of sufficient data and ambiguities in the data. Rock physics modelling can help to improve the consistency by ensuring that the petrophysical interpretations are also constrained by the elastic logs. There are three ways that rock physics can be used. First as a simple quality control, second to provide quantitative feedback to the petrophysics and third in a joint interpretation. The choice of method depending on the confidence achieved in the rock physics model.
