Seyed Reza Shadizadeh; Seyed Ramin Seyedi Abandankashi; Siyamak Moradi

Volume 10, Issue 1 , Winter 2021, , Pages 89-106

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

2. Effects of pH and Temperature on Oilfield Scale Formation

Jaber Azizi; Seyed Reza Shadizadeh; Abbas Khaksar Manshad; Naghi Jadidi

Volume 7, Issue 3 , Summer 2018, , Pages 18-31

http://dx.doi.org/10.22050/ijogst.2017.58038.1350

Abstract
  Water flooding is one of the most influential methods for pressure maintenance and enhanced oil recovery. However, water flooding is likely to develop the formation of oilfield scale. Scale formation in reservoirs, due to the mixing of injection water and formation water, could cause formation damage ...  Read More

3. An Impressive Impact on Well Productivity by Hydrochloric Acidizing of Vuggy Carbonate Reservoir: A Case Study

Abolfazl Hashemi; Seyed Reza Shadizadeh

Volume 6, Issue 3 , Summer 2017, , Pages 12-28

http://dx.doi.org/10.22050/ijogst.2017.53900.1335

Abstract
  Hydrochloric acidizing is a routine operation in oil fields to reduce the mechanical skin. In this paper, practical acidizing in a typical carbonate oil reservoir located in the southwest of Iran is practiced, which shows an unexpected improvement after acidizing. To understand the acidizing effect on ...  Read More

4. Evaluation of a Naturally-derived Deflocculant (Terminalia Chebula) in Bentonite Dispersions

Jalal Neshat; Seyed Reza Shadizadeh

Volume 5, Issue 2 , Spring 2016, , Pages 21-44

http://dx.doi.org/10.22050/ijogst.2016.15788

Abstract
  The unwanted addition of salt to drilling causes flocculation which has an adverse effect on mud rheological properties. To treat the flocculated mud chemical, deflocculants are commonly used; however, their disadvantages such as negative environmental effects, lower tolerance to contamination, and toxicity ...  Read More

5. Minimizing Water Invasion into Kazhdumi Shale Using Nanoparticles

Aghil Moslemizadeh; Seyed Reza Shadizadeh

Volume 4, Issue 4 , Autumn 2015, , Pages 15-32

http://dx.doi.org/10.22050/ijogst.2016.12475

Abstract
  Fluid invasion from water-based drilling mud (WBDM) into the shale formations causes swelling, high pressure zone near the wellbore wall, and eventually wellbore instability problems during drilling operations. For the stability of the wellbore, physical plugging of nanoscale pore throats could be considered ...  Read More

6. Delineating Hydrocarbon Bearing Zones Using Elastic Impedance Inversion: A Persian Gulf Example

Haleh Karbalaali; Seyed Reza Shadizadeh; Mohammad Ali Riahi

Volume 2, Issue 2 , Spring 2013, , Pages 8-19

http://dx.doi.org/10.22050/ijogst.2013.3534

Abstract
  Reservoir characterization plays an important role in different parts of an industrial project. The results from a reservoir characterization study give insight into rock and fluid properties which can optimize the choice of drilling locations and reduce risk and uncertainty. Delineating hydrocarbon ...  Read More
