F003 Uncertainty estimation in seismic-based porosity and saturation inversion: Examples from unconsolidated and hard rock environments Abstract 1 Uncertainties associated with predicting pay saturation and porosity in the subsurface are related not only to seismic inversion accuracy resolution and confidence in rock-physics relations but also to diagenetic processes associated with porosity reduction processes and hydrocarbon migration into the reservoir. In this paper we use stochastic simulation techniques and formal Bayesian inversion to explore the uncertainty associated with porosity and saturation estimates obtained in two prototypical environments: a consolidated hard sand reservoir in east Texas and soft unconsolidated sediments in marine
