1. Analyzing the Illumination and Resolution in Seismic Survey Designing

Sadegh Saffarzadeh; Abbdolrahim Javaherian; Hossein Hasani; Maryam Sadri

Volume 7, Issue 4 , Autumn 2018, Pages 1-12

http://dx.doi.org/10.22050/ijogst.2018.101878.1416

Abstract
  Seismic modeling aids the geophysicists to have a better understanding of the subsurface image before the seismic acquisition, processing, and interpretation. In this regard, seismic survey modeling is employed to make a model close to the real structure and to obtain very realistic synthetic seismic ...  Read More

2. A Review of Reservoir Rock Typing Methods in Carbonate Reservoirs: Relation between Geological, Seismic, and Reservoir Rock Types

Ali Kadkhodaie-Ilkhchi; Rahim Kadkhodaie-Ilkhchi

Volume 7, Issue 4 , Autumn 2018, Pages 13-35

http://dx.doi.org/10.22050/ijogst.2019.136243.1461

Abstract
  Carbonate reservoirs rock typing plays a pivotal role in the construction of reservoir static models and volumetric calculations. The procedure for rock type determination starts with the determination of depositional and diagenetic rock types through petrographic studies of the thin sections prepared ...  Read More

3. 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 , Autumn 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

4. An Experimental Investigation of Water Effects on Asphaltene Surface Behavior through Interfacial Tension Measurements

Ramin Moghadasi; Jamshid Moghadasi; Shahin Kord

Volume 7, Issue 4 , Autumn 2018, Pages 45-58

http://dx.doi.org/10.22050/ijogst.2018.108233.1422

Abstract
  As a physiochemical property, asphaltenes are known to be one the most surface active compounds in crude oil. Due to such property, their behavior is most probably influenced by fluid-fluid interactions at the contact surface (interface). Potentially and naturally, in most cases, water is in contact ...  Read More

5. Numerical Investigation of the Impact of Inlet Channel Numbers on the Flow Pattern, Performance, and Erosion of Gas-particle Cyclone

Seyed Masoud Vahedi; Farzad Parvaz; Mohammad Kamali; Hasti Jafari Jebeli

Volume 7, Issue 4 , Autumn 2018, Pages 59-78

http://dx.doi.org/10.22050/ijogst.2018.98556.1409

Abstract
  The effect of adding extra inlet channels on the operation of the Stairmand Cyclone has been investigated numerically. The Reynolds stress model (RSM) and Eulerian-Lagrangian method were used to investigate the complex turbulent flow and cyclone performance. The impacts of one-way coupling and two-way ...  Read More

6. An Experimental and Theoretical Analysis of Foam Formation in the Sour Gas Sweetening Process

Mahmod Fatemi; Bahram Hashemi Shahraki

Volume 7, Issue 4 , Autumn 2018, Pages 79-89

http://dx.doi.org/10.22050/ijogst.2018.111128.1430

Abstract
  Use of amine solutions for the removal of acid gases such as carbon dioxide (CO2) and hydrogen sulfide (H2S) from natural gas is the most common method, and, in this process, operational problems because of foaming are reported. Foaming can lead to the entrainment of liquid into downstream process equipment ...  Read More
