Bayesian Facies Classification using depth trends and elastic values from Simultaneous and Facies-based Inversions: A Montney case study

Joaquin Aristimuno, Ikon Science

Abstract:

In this work we present and compare the results of applying a Bayesian facies classification using two types of Seismic Inversions: Simultaneous and Facies-based at the Montney formation.

The estimated elastic parameters are quite similar between facies-based and simultaneous inversion at the well locations that were used to build the Low-frequency Model (LFM) used for Simultaneous Inversion. Different absolute values, and therefore classification, were obtained when doing simultaneous inversion and using different well sets to build a different LFM. The methodology applied in both methods are quite different, where the facies-based inversion method provides a LFM.
