Abstract
  The spatial distribution of petrophysical properties within the reservoirs is one of the most important factors in reservoir characterization. Flow units are the continuous body over a specific reservoir volume within which the geological and petrophysical properties are the same. Accordingly, an accurate ...  Read More

Ali Khazaei; Hossein Parhizgar; Mohammad Reza Dehghani

Volume 3, Issue 3 , July 2014, , Pages 47-61

https://doi.org/10.22050/ijogst.2014.6621

Abstract
  In this work, artificial neural network (ANN) has been employed to propose a practical model for predicting the surface tension of multi-component mixtures. In order to develop a reliable model based on the ANN, a comprehensive experimental data set including 15 ternary liquid mixtures at different temperatures ...  Read More

Morteza Nouri Taleghani; Sadegh Saffarzadeh; Mina Karimi Khaledi; Ghasem Zargar

Volume 2, Issue 3 , July 2013, , Pages 11-24

https://doi.org/10.22050/ijogst.2013.3641

Abstract
  Porosity is one of the fundamental petrophysical properties that should be evaluated for hydrocarbon bearing reservoirs. It is a vital factor in precise understanding of reservoir quality in a hydrocarbon field. Log data are exceedingly crucial information in petroleum industries, for many of hydrocarbon ...  Read More
