Permeability is one of the most important characteristics of hydrocarbons bearing formations. Formation permeability is often measured in laboratory from cores or evaluated from well test data. However, core analysis and well test data are usually only available from a few wells in a field. On the other hand, almost all wells are logged. This paper presents a nonparametric model to predict reservoir permeability from a conventional well logs data using artificial neural network (ANN). The ANN technique is demonstrated with an application to one of Saudi oil fields. This field is the largest offshore oil field in the world and was deposited in a fluvial dominated deltaic environment. The use of conventional regression methods to predict permeability in this case was not successful. The ANN permeability prediction model was developed from some of the data set consisting of core permeability and well logs data from three early development wells. The ANN model was built and trained from some of the well logs data and their corresponding core measurements by using a back propagation neural network (BPNN). The resulted model was blind tested using data, which was withdrawn from the modeling process. The results of this study show that ANN model permeability predictions are consistent with actual core data. It could be concluded that the ANN model is a powerful tool for permeability prediction from well log data.
