Adaptive Ensemble-Based Optimisation for Petrophysical Inversion

Autor: Rémi Moyen, Théophile Gentilhomme

Publikováno v: Mathematical Geosciences. 53:349-373

This article introduces a new optimisation algorithm designed for sampling the solution space of non-linear, non-convex quadratic problems. This method has been specifically designed for inversion problems where multiple distinct scenarios must be ex

Publikováno v: 13th International Congress of the Brazilian Geophysical Society & EXPOGEF, Rio de Janeiro, Brazil, 26–29 August 2013.

We present a new history matching approach designed for highly detailed seismic derived prior models. An ensemble-based optimization method is used to integrate production data and quantify associated uncertainties. An adaptive multi-scale wavelet pa
