Study of the reliability of the determination of reservoir characteristics of productive formations in the Stretenskoye field using correlation analysis

Abstract

Abstract Storage properties (porosity) of productive strata at Stretenskoye field were determined using several methods of geophysical studies of wells. The filtration properties (permeability) are determined according to the interpretation of the hydrodynamic study materials under unsteady conditions. At the same time, the methods used in a number of cases showed different results. In order to avoid misinterpretation of the structure of void space and its properties, it is advisable to conduct studies to assess the reliability of all the methods. For this purpose, the paper used the tools of mathematical statistics such as correlation and multivariate regression analysis. As a result of the research, the authors gave the recommendations for the application of methods to determine the filtration and storage properties of reservoirs differentially for terrigenous and carbonate reservoirs of the studied field.
