Authors: M.M. Khasanov, A.I. Brusilovsky, R.A. Khabibullin, A.I. Odegov, D.A. Serebryakova (Gazpromneft NTC LLC, RF, Saint-Petersburg)

Key words: gas-oil ratio (GOR), PVT correlation, composition model.

This paper attempts to provide engineer with GOR-PVT correlation selection rules. Results provided as GOR-PVT correlation Maps of Applicability and procedure of calculation GOR by selected PVT correlation. The procedure was checked during PVT study of 77 oil fields.
