Abstract

ABSTRACT This paper evaluates the most frequently used empirical gas and oil PVT correlations for application in Egypt. Correlations are used to determine values for bubble point pressure, oil formation volume factor at saturation pressure, solution gas oil ratio, oil and gas formation volume factor and oil viscosity. Often, these properties are required for oil field computations when there are no experimental or laboratory measurements available. When only oil and gas gravities and reservoir pressure and temperature are available, it is imperative to use published correlations for making accurate estimates of the fluid's physical properties. A review of the correlations used, along with the statistical accuracy of these correlations when compared to Gulf of Suez and Western Desert field data, is provided in this paper.
