Determining Petrophysical Properties of Facies Using a Hierarchical History-Matching Method
Abstract/Contents
- Abstract
- This report outlines the master's degree research carried out to develop a history matching method which perturbs a geostatistically modeled permeability field. The goal of the research is to propose a methodology that can preserve geological information about permeability heterogeneity, which is strongly controlled by facies in many cases. The work is an extension of probability-perturbation-based history matching methods proposed by Caers1 and Kim and Caers2. In their work, the novel methodology was developed to perturb facies realization with facies having known permeability in order to obtain history match preserving underlying geological concepts. We extend their history-matching scheme to the cases where the within-facies permeability is not known.The methods investigated in this work are one-dimensional and multi-dimensional optimization techniques which perturb the histogram of permeability within each facies. The strength of this approach lies in a preservation of facies shape, while determining the petorphysical properties of each facies through a history matching. The applicability of the methodology was investigated using 2D and 3D synthetic reservoir models, which comprise sand and mud.
