Prediction of Bubble Point Pressure From Composition of Black Oils Using Artificial Neural Network

In the present study, an artificial neural network (ANN) constitutive model was developed to predict bubble point pressure for the case of Canadian data. The accuracy of prediction of bubble point pressure was compared using two sets of inputs to the model. One was based on composition of the oil and the other based on easily available parameters such as solution gas-oil ratio, reservoir temperature, oil gravity, and gas relative density. The performance of bubble point pressure prediction with ANN was compared with that of equation of state (EOS) and other available empirical correlations. It was found that ANN models can produce a more accurate prediction of bubble point pressure than the existing empirical correlations and EOS calculations.
