Ali Jelvegarfilband; Mohammad Ali Riahi; Majid Bagheri

Volume 11, Issue 1 , January 2022

http://dx.doi.org/10.22050/ijogst.2022.338963.1638

Abstract
  The petrophysical parameters of the Ghar Formation are characterized in this study. A combination of pre-stack seismic data gathers and well-log data is used to estimate water saturation and shale volume in the Ghar reservoir. For such a purpose, first, the highest possible correlation between the well ...  Read More

Bahram Habibnia; Omid Vallipour; Majid Alipour

Volume 10, Issue 4 , October 2021, , Pages 68-84

http://dx.doi.org/10.22050/ijogst.2022.307365.1614

Abstract
  The Qale-Nar oilfield is an asymmetric two-humped anticline located in the northernmost part of the Dezful embayment, in which the fractured Asmari carbonates are the primary reservoir rock. In this study, for the first time, the organic geochemistry of oils produced from the Asmari reservoir is used ...  Read More

Samuel Getnet Tsegaye

Volume 10, Issue 2 , April 2021, , Pages 28-50

http://dx.doi.org/10.22050/ijogst.2021.284524.1592

Abstract
  The lithofacies and environments of deposition interpretations of the Calub–Hilala field toward the central trough of Ogaden Basin were analyzed, and geophysical well logs from three deep exploration wells, namely Calub-1, Bodle-1, and Hilala-2, were used. A methodology was piloted in establishing ...  Read More

Identifying Gas-bearing Carbonate Reservoir Using Extended Elastic Impedance

Hessam MansouriSiahgoli; Mohammad Ali Riahi; Bahare Heidari; Reza Mohebian

Volume 9, Issue 3 , July 2020, , Pages 102-115

http://dx.doi.org/10.22050/ijogst.2020.218837.1535

Abstract
  It is difficult to identify the carbonate reservoirs by using conventional seismic reflection data, especially in cases where the reflection coefficient of the gas-bearing zone is close to that of the carbonate background. In such cases, the extended elastic impedance (EEI) as a seismic reconnaissance ...  Read More

Amplitude Variation with Offset Inversion Analysis in One of the Western Oilfields of the Persian Gulf

Benyamin Khadem; Abdolrahim Javaherian

Volume 8, Issue 2 , April 2019, , Pages 15-33

http://dx.doi.org/10.22050/ijogst.2018.125135.1444

Abstract
  Reservoir characterization has a leading role in the reservoir geophysics and reservoir management. Since the interests of the reservoir geophysics and reservoir managements are the elastic properties and reservoir properties of the subsurface rock for their purposes, a robust method is required for ...  Read More

Evaluation of Reservoir Properties Using Wireline Logs of Well Sarai-Sidhu-1, Punjab Platform, Central Indus Basin, Pakistan

Syed Waqas Haider; Mustafa Yar; Raja Ahtisham Ghafoor; Tallat Majeed Khan

Volume 7, Issue 4 , October 2018, , Pages 36-44

http://dx.doi.org/10.22050/ijogst.2018.95773.1400

Abstract
  The well Sarai Sidhu-01 is located on Punjab Platform, Central Indus Basin, Pakistan. Punjab Platform is the eastern part of Central Indus Basin, and tectonically it is the stable portion of Indus Basin, which was least affected during Tertiary Himalayan orogeny. This study attempts to decipher reservoir ...  Read More
