1. Seismic Attribute Analysis and 3D Model-Based Approach to Reservoir Characterization of “KO” Field, Niger Delta

James Sunday Abe; Kenneth Okosun

Volume 9, Issue 4 , Autumn 2020, Pages 1-28

http://dx.doi.org/10.22050/ijogst.2020.232984.1550

Abstract
  Modelling involves the use of statistical techniques or analogy data to infill the inter-well volume producing images of the subsurface. Integration of available data sets from “KO” field were used to identify hydrocarbon prospects and by means of interpolation, populate the facies and petrophysical ...  Read More

4. Screening of Enhanced Oil Recovery Methods in One of Iran’s Offshore Oil Fields

Mehdi Bahari Moghaddam; Mostafa Fathalizade

Volume 9, Issue 4 , Autumn 2020, Pages 68-84

http://dx.doi.org/10.22050/ijogst.2020.237415.1553

Abstract
  Enhanced oil recovery (EOR) is a vital part of the process of oil production from sandstone and carbonate reservoirs. Maintaining and increasing oil production from many fields require proper selection, design, and implementation of EOR methods. The selection of EOR methods for specific reservoir conditions ...  Read More

5. Simplified Automatic Seismic to Well Tying Using Smooth Dynamic Time Warping Technique in R

Afshin Amiri; Majid Bagheri; Mohammad Ali Riahi

Volume 9, Issue 4 , Autumn 2020, Pages 85-92

http://dx.doi.org/10.22050/ijogst.2020.234641.1552

Abstract
  Seismic well tying is a crucial part of the interpretation phase in exploration seismology. Tying wells usually involves forward modeling a synthetic seismogram from sonic and density logs and then matching the obtained synthetic seismogram to the seismic reflection data. A huge amount of time is required ...  Read More

7. Application of SnO2/Alumina Nanocatalyst in Removal of Naphthenic Acids from Crude Oil

Taleb Eidy; Seyed Ali Hosseini; Ghasem Marandi

Volume 9, Issue 4 , Autumn 2020, Pages 115-123

http://dx.doi.org/10.22050/ijogst.2020.250990.1565

Abstract
  The separation of naphthenic acids from crude oil is difficult, and the presence of such materials in crude oil reduces its value. In this work, using catalytic esterification with methanol, naphthenic acids of crude oil were removed to reduce their harmful effects. SnO2/γ-Al2O3 nanocatalyst was ...  Read More
