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) DETERMINING 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.(FIGURE 1) |
