A method of determining an in situ PVT property of a hydrocarbon reservoir fluid that is present in a hydrocarbon-bearing formation layer traversed by a borehole, which method comprises the steps of: a) calculating along the hydrocarbon-bearing formation layer the pressure gradient; and b) determinin g the in situ PVT property from the pressure gradient using an empirical relation that had been obtained by fitting a curve (11) through previously obtained data points (12, 13, 14) comprising the measured PVT property as a function of the pressure gradient. |
