Pressure-volume-temperature empirical formulations for undersaturated omani oils

Research output: Contribution to journalArticle

Abstract

Pressure-Volume-Temperature (PVT) empirical correlations result from analysis of experimental data collected from laboratory measurements of phase behavior properties of hydrocarbon systems. The correlations are only applicable for the tested hydrocarbons. They could nevertheless be used to predict PVT properties of similar hydrocarbons with pressures and temperatures falling within the measurements' data range. The developed correlations are mostly, local, some are "region-bound" and a few are global. Regional and global correlations are used with caution. The reason being that hydrocarbon systems from different regions have different composition and paraffinicity, regardless of comparable temperature and pressure ranges. As a result and due to a complex geology resullting from unique depositional environments of most Omani reservoirs, a local correlation to derive PVT properties for Omani crude oils is needed. The correlations could also be used to supplement PVT experiments often time consuming and extremely costly. In this paper, the developed correlations are derived for undersaturated Omani black-oil.
