... in the system. The microbubble capture and retention due to the presence of asphaltenes make the bubble release time much longer than when the asphaltenes are absent. This phenomenon has not been accounted for in the past. A new equation of state is generated that satisfies the PVT data for various asphaltene...

... measurement, was developed. This paper presents and discusses how a one dimensional, equation of state (EOS) compositional model is successfully used to predict, with confidence, miscibility conditions (i.e. mixtures of NGL with lean gas or acid gas at reservoir temperature and pressure). The 1-D model...

... fluidbehavior for engineering calculations. In this paper four field examples arepresented to illustrate (1) how to use equation of state (EOS) oilcharacterization to check the accuracy of fluid sampling procedures andlaboratory fluid property measurements, and (2) how to use EOS oilcharacterization to check...

... Abstract A new mixing rule for using with the commonly employed cubic equations of state is proposed. It is applied for petroleum mixture vapor-liquid equilibrium computations, and the results are compared to those from the conventional calculations and the experiment data obtained...
