Mathematical Modelling of the Bashkir’s and Serpukhiv’s Sandstones of the Yablunivske Field Based on Petrophysical Data

Abstract

Summary The Yablunivske field is one of the most depleted field of Dnipro-Donetsk Depression, but at the same time it is the place of implementation of the production program for the modernization and intensification of the fields. Obtaining an understanding of the characteristics of the sedimentary rocks allows us to make conclusions about their possibility to hydrocarbon production. The authors have creating a basis for further modelling and the analysis of indicators of petrophysical parameters and the selection of the main correlating dependencies. The purpose of this work is to create a mathematical model of the rocks of the Bashkir’s and Serpukhiv’s layers of the well 1 of the Yablunivske field based on petrophysical data. The statistical analysis consisted in the construction of histograms of the distribution of the values of each of the parameters under different conditions, construction of the dependences of petrophysical parameters. The authors have achieved the results by creating the following dependencies, such as: bulk - mineral density before extraction, bulk density - coefficient of open porosity before extraction, bulk density - coefficient of open porosity after extraction, coefficient of permeability - coefficient of open porosity before extarction, coefficient of permeability - coefficient of open porosity after extraction.
