Newly discovered oil fields’ foundation in various world regions requires a large number of expensive analytical and experimental studies and significant material investments. Reservoir and production engineering requires huge amount of experimental data in geology, hydrodynamics, chemistry and also assumes that oil field operator has modern computing systems (software) and highly qualified personnel.
At the initial stage of field development, we often have insufficient initial data, therefore, it is necessary to use correlations obtained from analogous oil deposits. Usually, this data belongs to USSR period.
We performed generalization of all available experimental material on PVT analysis of Eocene oil fields in the Lago Sur region (Venezuela) and also analyzed set of former USSR oil field analogues, taken from published data. This information became a basis for correlations of some basic properties of oil and gas in the flash gas liberation process. As a rule, we know a set of oil and gas properties from the PVT analysis. Usually we know the degassed oil density at standard conditions, but don’t know the density of gas-saturated oil at reservoir conditions.
The importance of the present research is the fact that one may use our correlation to calculate oil and gas properties of the Eocene deposits in the Lago Sur region or similar deposits in case of non-reliable or insufficient fluid data.
