This paper covers a selection of 28 wells of Zavolzhsky superhorizon of Mikhailovsk and Kopey-Kubovsk fields, upon polymer-acid treatment, with 39 parameters for each. Regression and cluster analyses were made, principal components method was applied. Graphs were built and calculated using Statistica 6.0 software. The regression equation after the analysis was obtained and dependency plot between observed and predicted values of well flow rate growth was drawn. Wells were divided into clusters.
