Application of artificial neural networks and fuzzy logics to estimate porosity for Asmari formation

open access: yesEnergy Reports, 2021
Porosity estimation is one of the essential issues in petroleum industries to distinguish the reservoir characteristics properly. Therefore, it is of importance to predict porosity with the optimum way to reduce the logging tests. In this study, artificial neural network and fuzzy logics are considered efficient techniques to predict the Asmari ...
