Abstract

Summary

In this paper, we propose a two tiered inversion strategy that aims to address and better explore the solution space during seismic inversion and reservoir characterisation. First a range of plausible geological prior scenarios are defined in terms of layer configurations and horizon/picking uncertainty, number of facies and their corresponding abundances, and rock property trends and relationships (with associated uncertainties). Then, per scenario, stochastic Markov chain Monte Carlo sampling (McMC) is performed to create equiprobable realisations from the posterior distribution. The workflow is applied to a producing North Sea field and used to determine areas of significant uncertainty in oil presence and abundance.
