Key words: grouping, cluster analysis, sheshminskiy horizon, Tournasian stage, oil rock parameters.
Today on the territory of Republic Tatarstan discovered more than 207 oil fields uniting approximately 3000 oil deposits. Of particular interest is the grouping of oil fields on parameters of porosity, oil rock saturation and permeability, oil density, viscosity, resin and sulfur content and etc. The grouping allows to estimate similarity and dissimilarity of productive layers, to multiply successful technology and layer influence methods among object of one group, allows to confirm recovery schemes and enhancing oil recovery methods and etc. The grouping on the base of cluster analysis and geo information systems is shown on the example of ufimian and tournasianoil deposits.
