Fluid pressure regimes

Lecture on fluid pressure and using downhole pressure measurements to locate contacts.

That was the best explanation visually of FWL vs OWC I’ve ever seen - thanks a lot!

Thank you sir that was very helpful!

the best video

[@marilynmacarthur2801]

Thank you for that very informative video! it was very helpful to know about the cap pressure influence on the OWC where the oil column appears to be ~1-2m above the water gradient. If you had a large enough delta in API in a pool (for example: 14 API in the south and 19 API in the north) and no real stratigraphic or structural barriers. Could you have a different OWC in the south vs north due to that cap pressure effect (~1.5m difference between the two)?

Marilyn - yes this is possible. If the same capillary pressure is imposed across the field, but there is a variation in density, then a difference in apparent OWC can occur. However, over geological time, these compositional differences may even out - normally changes in density of the oil are seen with depth.
