oa Do Fluid Compositions and Reservoir Pressure Tell Us the Same Thing About Reservoir Segmentation?

A multitude of reservoir fl uid parameters (pressure, GOR, molecular composition, etc.) are usually available for reservoir segmentation<br>interpretations. These parameters are controlled by multiple reservoir processes including, but not limited to, reservoir charge/fi lling,<br>fl uid mixing through darcy fl ow/advection/diffusion, gravity segregation, biodegradation, fractionation, and differential leakage. The<br>time scales for these processes to operate in reservoirs will be the key to understanding the relative signifi cance of fl uid data to reservoir<br>compartmentalization studies.
