2. Support Vector Machine Based Facies Classification Using Seismic Attributes in an Oil Field of Iran

Majid Bagheri; Mohammad Ali Riahi

Volume 2, Issue 3 , Summer 2013, Pages 1-10

http://dx.doi.org/10.22050/ijogst.2013.3640

Abstract
  Seismic facies analysis (SFA) aims to classify similar seismic traces based on amplitude, phase, frequency, and other seismic attributes. SFA has proven useful in interpreting seismic data, allowing significant information on subsurface geological structures to be extracted. While facies analysis has ...  Read More

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

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

http://dx.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

Mohsen Karimian; Nader Fathianpour; Jamshid Moghaddasi

Volume 2, Issue 3 , Summer 2013, Pages 25-36

http://dx.doi.org/10.22050/ijogst.2013.3642

Abstract
  Porosity is considered as an important petrophysical parameter in characterizing reservoirs, calculating in-situ oil reserves, and production evaluation. Nowadays, using intelligent techniques has become a popular method for porosity estimation. Support vector machine (SVM) a new intelligent method with ...  Read More

5. An Experimental Study of CO2-low Salinity Water Alternating Gas Injection in Sandstone Heavy Oil Reservoirs

Hadi Zolfaghari; Alireza Zebarjadi; Omid Shahrokhi; Mohammad Hosein Ghazanfari

Volume 2, Issue 3 , Summer 2013, Pages 37-47

http://dx.doi.org/10.22050/ijogst.2013.3643

Abstract
  Several studies have shown that oil recovery significantly increased by low salinity water flooding (LSWF) in sandstones. However, mechanism of oil recovery improvement is still controversial. CO2 that develops buffer in presence of water is expected as a deterrent factor in LSWF efficiency based on ...  Read More

6. An Experimental Study of Alkali-surfactant-polymer Flooding through Glass Micromodels Including Dead-end Pores

Mohsen Esmaeili; Ali Heydarian; Abbas Helalizadeh

Volume 2, Issue 3 , Summer 2013, Pages 48-56

http://dx.doi.org/10.22050/ijogst.2013.3644

Abstract
  Chemical flooding, especially alkaline/surfactant/polymer flooding, is of increasing interest due to the world increasing oil demand. This work shows the aspects of using alkaline/surfactant/polymer as an enhanced oil recovery method in the porous media having a high dead-end pore frequency with various ...  Read More

7. Fluid Injection Optimization Using Modified Global Dynamic Harmony Search

Mohammad Khalili; Riyaz Kharrat; Karim Salahshoor; Morteza Haghighat sefat

Volume 2, Issue 3 , Summer 2013, Pages 57-72

http://dx.doi.org/10.22050/ijogst.2013.3645

Abstract
  One of the mostly used enhanced oil recovery methods is the injection of water or gas under pressure to maintain or reverse the declining pressure in a reservoir. Several parameters should be optimized in a fluid injection process. The usual optimizing methods evaluate several scenarios to find the best ...  Read More
