E-FACIES

E-FACIES partitions the well log data before building correlation and is based on Multivariate Analysis of Well Logs. Generally a suite of well logs can provide valuable but indirect information about mineralogy, texture, sedimentary structure, fluid content and hydraulic properties of a reservoir. The distinct log responses in the formation represent electrofacies that often can be correlated with actual lithofacies identified from cores, based on depositional and diagenetic characteristics.
