Estimation of neutron logs from other logs provides determination of artificial neutron logs in wells without neutron log. Application of artificial neural networks such as prediction and simulation is notable. Some neutron logs might be lost, thus in this study we use neural network and two logs (Density and sonic) to produce artificial neutron logs. A network includes four layers (one input layer, two hidden layers and one output layer) was designed.
