Abstract
Summary
We employed fluid thermodynamics and the equation of state to calculation of the speed of sound and density of fluid mixture in the complex fluid system. Using this technique, the predictability of rock physics modelling, and subsequent seismic modelling are significantly improved. The choice of equation of state is dependent on its predictability of available experimental data, and its calculation stability for the mixture of interest. The technique is embedded within the rock physics model for carbon capture and enhanced oil recovery studies where the feasibility of the seismic monitoring is studied.
