... those under consideration. A common approach is to attempt tuning available correlations to measured data at hand by modifying correlation coefficients. This is the approach adopted here as correlations apparently do not exist for the region containing the studied oilfields. The first step...

... whether these key factors are correlated with each other, we conduct bi-variable analysis. The results are shown in Fig. 3 . As we can see, initial water saturation Swi is negatively correlated with initial oil saturation Soi (correlation coefficient of −0.94); TVD is correlated with reservoir...

... of the newly developed model. The statistical analyses showed a positive outcome whereby the proposed model obtained the lowest average absolute percentage relative error of 5.17% and the highest correlation coefficient of 96.8%. The best model tested among the other models has five input parameters...
