Define a Tank Model for Thin Oil rim reservoir

Post by Aby »

In a thin oil rim reservoir, the wells that have been perforated in the oil column produce crude with an API close to 35. While the wells perforated in the gas cap produce condensate with an API close to 50.
I would like to know the mechanism to model this mutli-phase behavior of a reservoir in MBAL and in simulation studies. I'm particularly interested to know about the fluid description in terms of PVT properties that can be used to model this behavior.

In this type of reservoir, the formal way is to construct a compositional model but practically you can run black oil model considering that the Bubble point pressure is the reservoir pressure at GOC.

Plot the bubble point pressure versus depth and match the GOC point.
