Rock Physics Issues in Carbonates

Carbonates are very complex, increasing the difficulty of developing rock physics models to describe geophysical responses. However, since carbonates make up such a large fraction of the hydrocarbon reserves in the world, it is important to develop such models. In this paper, we discuss a rock physics model that is applicable to clastic and carbonate rocks, and across a range of grain sizes. It incorporates known or relatively easily measurable basic parameters. We demonstrate the impact of several physical effects on geophysical responses.
