Abstract

Electrofacies is a deterministic or analytical way to perform well logs data partitioning, which shows variation of geologic or reservoir characteristics. In this paper, we used well logs of two cored wells at one of the oil fields in south of Iran. An initial electrofacies model was developed based on well logs which included of 25 facies. Corresponds facies in this model merged together according to core micro facies analysis that showed 5 sedimentary facies associations. So it optimized by transmuting to new model (5 facies). Results of optimized model showed good conformity with core micro facies (in cored wells). Finally, we propagated it to all wells and simulated sediment facies in all wells of the subjected oil field.
