The operating condition of any reservoir in terms of pressure and temperature is a key to determine how its reservoir fluids properties behave. In fact, reservoir fluids properties will behave differently under different conditions of pressure and temperature. The current study therefore investigates the effects of Ultra High Pressure High Temperature (UHPHT) conditions on reservoir fluids properties, which include: Bubble point pressure, Gas solubility, Density, Oil viscosity, Oil formation volume factor, Oil gravity, Surface tension and Compressibility factor. The aim of this paper is to solve various problems associated with the petroleum exploration, the search for additional reserves, the characterization of various kinds of reservoirs and the evaluation of recovery factor of each reservoir. The results obtained by the empirically derived modeling equations are used as the platform for the modified correlations and the corresponding plots of UHPHT against each reservoir property are found to be consistent with those reported for the reservoir fluids properties in the literature. At ultra HPHT conditions, oil density, oil viscosity, oil gravity, surface tension and compressibility factor decrease while bubble – point pressure, gas solubility and oil formation volume factor increase.
