1. Determination of Minimum Miscibility Pressure (MMP) using PVTi Software, Eclipse 300 and Empirical Correlations

Vahid Karamnia; Siavash Ashoori

Volume 10, Issue 1 , Winter 2021

http://dx.doi.org/10.22050/ijogst.2021.252493.1567

Abstract
  One of the most important factors through the miscible gas injection process is to determine the Minimum Miscibility Pressure. According to the definition, the minimum miscibility pressure is the minimum pressure at which, at a constant temperature, the oil and gas injected can dissolve together to form ...  Read More

Volume 10, Issue 1 , Winter 2021

http://dx.doi.org/10.22050/ijogst.2021.234857.1555

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

Abiodun Ogbesejana; Oluwadayo Sonibare; Zhong Ningning; Oluwasesan Bello

Volume 8, Issue 2 , Spring 2019, , Pages 34-52

http://dx.doi.org/10.22050/ijogst.2018.128598.1454

Abstract
  Crude oils and source rocks from the northern and offshore Niger Delta basin, Nigeria, have been characterized by gas chromatography-mass spectrometry in terms of their origin and thermal maturity based on the distribution of chrysene and its derivatives. The crude oils and source rocks were characterized ...  Read More

4. Characterization of Liquid Bridge in Gas/Oil Gravity Drainage in Fractured Reservoirs

Behrouz Harimi; Mohsen Masihi; Mohammad Hosein Ghazanfari

Volume 8, Issue 2 , Spring 2019, , Pages 73-91

http://dx.doi.org/10.22050/ijogst.2018.140366.1465

Abstract
  Gravity drainage is the main mechanism which controls the oil recovery from fractured reservoirs in both gas-cap drive and gas injection processes. The liquid bridge formed between two adjacent matrix blocks is responsible for capillary continuity phenomenon. The accurate determination of gas-liquid ...  Read More

5. 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

6. 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

7. A Novel Approach to Measuring Water and Oil Relative Permeabilities in Two-phase Fluid Flow in Porous Media

Azadeh Mamghaderi; Behzad Rostami; Seyed Hamed Tabatabaie

Volume 7, Issue 2 , Spring 2018, , Pages 14-34

http://dx.doi.org/10.22050/ijogst.2018.106164.1425

Abstract
  In this study, direct laboratory measurements of unsteady-state imbibition test are used in a new approach to obtain relative permeability curves with no predetermined functionality assumptions. Four equations of continuity, Darcy’s law, cumulative oil production, and water fractional flow are ...  Read More

8. Integrated Characterization and a Tuning Strategy for the PVT Analysis of Representative Fluids in a Gas Condensate Reservoir

Shahriar Osfouri; Reza Azin; Hamid reza Amiri; Zahra Rezaei; Mahmoud Moshfeghian

Volume 7, Issue 1 , Winter 2018, , Pages 40-59

http://dx.doi.org/10.22050/ijogst.2017.78181.1383

Abstract
  Gas condensate reservoirs are characterized by a distinctive retrograde behavior and potential for condensate drop out during production and sampling. Efficient modeling of gas condensate reservoir requires careful phase behavior studies of samples collected prior to and during the production life of ...  Read More
