Classification of the investigated objects is usually worked out by various methods. At this time, the marks as well as the number of parameters taking into account at the result of the research depend on the investigators experience and approach manner. Thus, mathematical methods are used and one of the most used ones in the experiment is the method of cluster analysis. On the basis of correlated geophysical parameters by applying cluster analysis, classification of layers according to their saturation features and facial composition has been looked into in the article. The well sections of Guneshly, Chirag, Azeri, Kapaz fields have been accepted as the investigation object for the layer groups of Pereria, OGC, OGS of PL in the zone of Absheron - in Balakhany, the correlation index among geophysical parameters for each well has been calculated, the condition value of special resistance of oil - gas layers according to sections has been determined. According to this estimation, layers have been classified for their saturation features and facial composition as a result of cluster analysis and it allows to reveal perspective oil - gas areas. As the result of investigations it has been known that classification of the object for its saturation features and facial composition by cluster analyses allows to classify perspective oil - gas areas on the basis of the marks of correlated three geophysical parameters and it increase geological productivity of GIS.
