Wu, R. Measured fluid properties from four reservoirs are used to compare property prediction results using an equation of state EOS method and different PVT correlations available in the literature.
Petroleum Geoscience ;; 7 2 : — Simulation of improved recovery processes from gas condensate and volatile oil reservoirs is significantly affected by the match of experimental PVT data. Therefore, a proper characterization of the mixture composition and tuning of the equation of state used are crucial for the accuracy of the reservoir model. This paper presents an efficient method for phase behaviour matching by non-linear regression. The constraints introduced by the boundaries of the regression variables are eliminated by a suitable change of variables. This leads to an unconstrained optimization problem, solved by an original implementation of the Levenberg—Marquardt algorithm. A new, rigorous generalized quadrature method is developed for the characterization of the continuous portion of the mixture, which can be applied to any distribution function.
In the literature there are several studies comparing the accuracy of various models in describing the PvT behavior of polymers. However, most of these studies do not provide information about the quality of the estimated parameters or the sensitivity of the prediction of thermodynamic properties to the parameters of the equations. Furthermore, there are few studies exploring the prediction of thermal expansion and compression coefficients. Based on these observations, the objective of this study is to deepen the analysis of Tait, HH Hartmann-Haque , MCM modified cell model and SHT simplified hole theory equations of state in predicting the PvT behavior of polymers, for both molten and solid states. The results showed that all equations of state provide an adequate description of the PvT behavior in the molten state, with low standard deviations in the estimation of parameters, adequate sensitivity of their parameters and plausible prediction of specific volume, thermal expansion and isothermal compression coefficients.
This title covers a wide range of topics related to the Pressure Volume Temperature PVT behavior of complex hydrocarbon systems and documents the ability of Equations of State EOS in modeling their behavior. This book aims to provide the practicing engineer and engineering student with tools needed to solve problems that require a description of the PVT of hydrocarbon systems from their compositions. Because of the dramatic evolution in computational capabilities, petroleum engineers can now study such phenomena as the development of miscibility during gas injection, compositional gradient as a function of depth and the behavior near critical hydrocarbon systems with more sophisticated EOS models.

Боюсь, что. И мы должны его найти. Найти тихо. Если он почует, что мы идем по его следу, все будет кончено.
Вот. Если мы - охранники общества, то кто будет следить за нами, чтобы мы не стали угрозой обществу. Сьюзан покачала головой, не зная, что на это возразить. Хейл улыбнулся: - Так заканчивал Танкадо все свои письма ко. Это было его любимое изречение.
На мониторе появилось символическое изображение конверта - это значило, что пришло сообщение по электронной почте. Сьюзан бросила быстрый взгляд на Хейла, но тот был всецело поглощен своим компьютером. Затаив дыхание, Сьюзан дважды щелкнула по конверту.
