Selection of PVT Correlations

This chapter discusses the approaches to select appropriate pressure, volume, and temperature (PVT) correlations. It starts by highlighting the problem of large variation of PVT properties calculated from the same inputs. It then discusses the approaches for PVT correlation selection (e.g., based on geographical location, fluid type, application, data ranges and ranking, and expert systems). The chapter also discusses the limitations of each PVT correlation selection technique. It explains with example calculations different techniques that can be used for correlations selection.
