Abstract
  In recent years, the use of natural surfactants as surface active agents in chemical methods of oil recovery over chemical surfactants has been under consideration due to the absence of environmental problems. In this study, a new plant, Albizia julibressin (Albizia), was introduced as a natural surfactant. ...  Read More

2. Separating Well Log Data to Train Support Vector Machines for Lithology Prediction in a Heterogeneous Carbonate Reservoir

Volume 4, Issue 2 , Spring 2015, , Pages 1-14

http://dx.doi.org/10.22050/ijogst.2015.9588

Abstract
  The prediction of lithology is necessary in all areas of petroleum engineering. This means that to design a project in any branch of petroleum engineering, the lithology must be well known. Support vector machines (SVM’s) use an analytical approach to classification based on statistical learning ...  Read More

3. A Novel Combinatorial Approach to Discrete Fracture Network Modeling in Heterogeneous Media

Saeed Balouchi; Siyamak Moradi; Mohsen Masihi; Ali Erfaninia

Volume 2, Issue 1 , Winter 2013, , Pages 42-56

http://dx.doi.org/10.22050/ijogst.2013.3037

Abstract
  Fractured reservoirs contain about 85 and 90 percent of oil and gas resources respectively in Iran. A comprehensive study and investigation of fractures as the main factor affecting fluid flow or perhaps barrier seems necessary for reservoir development studies. High degrees of heterogeneity and sparseness ...  Read More

4. Prediction of Nitrogen Injection Performance in Conventional Reservoirs Using the Correlation Developed by the Incorporation of Experimental Design Techniques and Reservoir Simulation

Ahad Fereidooni; Masoud Fereidooni; Siyamak Moradi; Ghasem Zargar

Volume 1, Issue 1 , Autumn 2012, , Pages 43-54

http://dx.doi.org/10.22050/ijogst.2012.2774

Abstract
  Enhanced oil recovery using nitrogen injection is a commonly applied method for pressure maintenance in conventional reservoirs. Numerical simulations can be practiced for the prediction of a reservoir performance in the course of injection process; however, a detailed simulation might take up enormous ...  Read More
