Abstract

Elastic properties often derived by inverting seismic and well-log data, form important input for reservoir engineering calculations and simulation studies. Often in absence of site-specific measurements at reservoir temperature and pressure, empirical models or data from analog formations are used. However, elastic properties of rocks are controlled by variation in saturant type, effects of pressure and temperature, in addition to rock heterogeneity. This paper discusses the effects of fluids, frequency and heterogeneity on the elastic properties of carbonate rocks.
