Popis: Petroleum reservoir fluid is commonly classified as individual components of C1 – C6 and lumped-up component of C7+. C7+ are hydrocarbon components of C7-heptane and above, that is, heavy hydrocarbons that are minimal in natural gas. De-lumping or splitting of C7+ into individual components is vital for accurate and efficient estimation of fluid properties. A number of correlations exist in literature and pressure-volume-temperature software for this. The least accurate and simple model by Lohrenz, Bray & Clark (1984) was modified in this work. Efficiency of the new model is highly comparable with existing models in the rigorous PVT systems for computing intensive and extensive natural gas properties.
