Abstract

Over the last 60 years or so, many rock<br>physics theoretical and empirical relations had been<br>proposed and applied as a guide to seismic and log<br>interpretation. With the recent advances in AVO<br>processing and interpretation and elastic inversion,<br>these rock physics transforms had proven to be<br>powerful tools to the explorationists.<br>Among these transforms there are some<br>theoretical models that establishes physically based<br>relations between petrophysical rock properties to its<br>seismic behavior, but usually it depends on many<br>parameters related to rock and pore structure and<br>composition. On the other hand, there are numerous<br>empirical or semi-empirical relations that require<br>easily obtained parameters, but generally are strictly<br>valid only on particular rock types similar to those<br>used for the transform deduction.<br>On this paper we discuss some popular rock<br>physics relations and propose modifications to typical<br>and important Brazilian rocks based on laboratory<br>measurements.
