Correlations of Reservoir Oil Properties: Miranga Field, Brazil

Placeholder Show Content


This report presents correlations of PVT and viscosity properties of reservoir oils in the Miranga Field, Brasil. The basic data for the correlations came from laboratory PVT reports fluids from 20 wells in that field.It was found that bubble point pressures and bubble point formation volume factors could be correlated using the parameters suggested by Standing for California crude oil Systems (1). However, better results were obtained when the fluids from the Member (Reservoir) Santiago and Kenber Catu were correlated separately.Viscosity of reservoir oils at this bubble point state were correlated by means of the relationships developed by Beggs and Robinson (9). It was found that Kiranga Field oils were considerably more viscous than indicated by Beggs and Robinson correlation and suitable correction factors were developed. New correlations were developed for obtaining the viscosity of gas saturated oils at pressures below their bubble point pressure and for undersaturated oils at pressures above their bubble point pressure.
