Abstract
Abstract The procedure presented in this paper offers a way to combine and integrate black-oil PVT data obtained from several wells at various depths in a consistent and easy manner, especially when the PVT properties exhibit variation with depth and an EOS model is not readily available. In principle, it is similar to normalizing and de-normalizing SCAL data. Although the method was primarily intended to honor and consistently take into account vertical variation of black oil PVT properties, it can also be used to reliably estimate oil PVT properties at elevations close to the GOC where reliable fluid sampling may not be possible due to gas coning or cusping during sampling operation. The following are the main benefits of the method: Detecting and representing vertical variation of fluid properties in a reservoir or compartment especially when access to an EOS package is not readily availableVerifying reservoir compartmentalization by identifying lateral variations in PVT propertiesValidating PVT parameters and their variations with depthGiven sample PVT data from various depths, generating representative black oil PVT tables at any required depth for use in black oil simulation
