Issues of hydrocarbon prediction with neural network methods

Neural network technology has been applied in the hydrocarbon prediction since 90's. Many scholars endeavored to study the neural network technology itself and its application in the hydrocarbon prediction. Their efforts bring forth the combination of neural network with different mathematical models, and yield significant application results. According to the basic principles of neural network techniques for the hydrocarbon prediction, this article discusses briefly the different mode, characteristics, and application conditions of neural network techniques in hydrocarbon prediction, and then analyzes some typical problems encountered when neural network techniques are applied to the hydrocarbon prediction, and finally put forward a outlook for the development trends of neural network technology in the hydrocarbon prediction.
