A facies classification approach based on cross recurrence plots

Abstract

Facies classification for well log data is an important task that helps facilitate the estimation of some other properties such as permeability. porosity. and liquid content. This paper presents a new approach for facies classification based on cross recurrence plots from well log data. The proposed mothod is evaluated using real well log data collected in Cuu Long basin. The experimental results show that the approach is efficient for facies classification, especially when the data has a small number of well log curves. This is very meaningful in real world implementation where the collection of well log measurements is either difficult or expensive.
