...). The composition of the gases, when corrected for the effects of OBM can be related to the phase and GOR of the fluid in formation via the correlation of the C1-C5 components to large PVT datasets and, in appraisal and development settings, to local PVT data.

When a sample of this oil is irradiated with UV light, some of the radiant energy is absorbed by the fluorescing molecules in the oil. The absorbed energy temporarily excites these molecules to a higher energy...
