Improved Dead Oil Viscosity Model

Ulaeto Ubong, Oyedeko K.F.K


This research work developed two new dead oil viscosity correlations: a general correlation and typical Niger Delta crude correlation, with large data range. The dead oil viscosity, affects the accuracy of viscosity models, especially when used in engineering problems involving fluid flow in porous media and particularly reservoir simulation. An accurate estimate of its value is therefore a very necessary concern. The models were developed using Linear and Non-Linear Multiple regression analysis. Multiple statistical assessments were employed to evaluate the accuracy of these models. The models are solved using Matlab and Microsoft Excel to obtain the General Model correlation coefficient of 0.870 and that of Typical Niger Delta Crude coefficient of correlation was 0.94. The models also gave better performance plots compared to existing models.
