Facies and Lithofacies Classifications from Well Logs

  • Y. Z. Ma


This chapter presents methods for classifying lithofacies from well logs. Lithofacies are a discrete variable that describes categories of the rock quality, defined as having two or more states. Lithofacies represent small- to intermediate-scale heterogeneities in geological analysis of subsurface formations. Different lithofacies often have different petrophysical properties and can impact subsurface fluid flow. Cores are generally limited, and lithofacies data are often derived from well logs in reservoir characterization.
