Abstract
Lumping methods for oil components require a more detailed approach to refine the description of fluids in an oil production area. These methods allow you to gradually increase the dynamics of the behavior of hydrocarbon deposits and increase their reserves. To date, the lumping method is relevant as an attractive way to spend on reservoir compositional modeling. The authors of the article describe PVT-calculations that have been developed for many years of illness, in the treatment of diseases of the cardiovascular system. They explain the approaches of different lumping methods. This article discusses different types of lumping methods such as classical, statistical, and machine learning based lumping.
