Volumetric liquid: vapor ratios generated with a confocal laser scanning microscope are used along with pressure-vapor-temperature (P-V-T) modeling software to estimate the composition, P-T phase envelope, and isochore of single petroleum inclusions in the North Sea's Judy and Alwyn fields. In both cases, the gas condensates currently in the reservoirs formed by the emplacement of gas into preexisting oil accumulations. Pressure histories of individual units in each field are also revealed, providing the kind of data needed to determine the permeability and fluid flow histories of sedimentary basins.
