... ABSTRACT New empirical PVT correlations for Gulf of Mexico (GOM) oils have been developed as a function of commonly available field data. Correlations have been developed for: bubblepoint pressure, solution gas oil ratio at bubblepoint pressure, oil formation volume factor...

... Abstract Reservoir simulation of variable bubblepoint processes such as water or gas injection into black oil reservoirs often requires extrapolation of reservoir fluid properties to pressures above original bubblepoint pressure. This has been known for over twenty years; however, to date...

... of numerous reservoir and fluid properties on the calculated curves are investigated. Bubblepoint pressure and reservoir depletion have a significant effect on the curves. A generalized dimensionless IPR based on nonlinear regression analysis of simulator results is developed. This IPR curve is then used...
