Calculating the optimal time of Fishing operations during drilling in the Gachsaran oil field

Seyed Reza Shadizadeh; Sina Khajehniyazi

Articles in Press, Accepted Manuscript, Available Online from 30 December 2023

  Fishing operations are one of the most important parts of drilling operations. If the fishing operation fails, the other direction should be considered to continue drilling and reach the desired depth, which can be achieved by using sidetracking operations. The long-term fishing operation increases the ...  Read More

Enhancing Oil Recovery from Oil-Wet Carbonate Rock by Wettability Alteration and interfacial tension Reduction Using Hawthorn Leaves Extract as a New Natural Surfactant

Seyed Reza Shadizadeh; Amin Derakhshan

Volume 11, Issue 3 , July 2022, , Pages 23-36

  Oil recovery from oil-wet carbonate rock is a significant challenge in the oil industry. The present study investigates the influence of the natural surfactant Hawthorn leaves extract (HLE) on oil recovery from carbonate rock. Two chemical surfactants, sodium dodecyl sulfate (SDS) and dodecyl tri methyl ...  Read More

Experimental Investigation Used of Albizia Julibrissin Extract as a Plant Surfactant on Oil Recovery

Seyed Reza Shadizadeh; Seyed Ramin Seyedi Abandankashi; Siyamak Moradi

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

  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

Effects of pH and Temperature on Oilfield Scale Formation

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

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

  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

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 , July 2017, , Pages 12-28

  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

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

Jalal Neshat; Seyed Reza Shadizadeh

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

  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

Minimizing Water Invasion into Kazhdumi Shale Using Nanoparticles

Aghil Moslemizadeh; Seyed Reza Shadizadeh

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

  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

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

Haleh Karbalaali; Seyed Reza Shadizadeh; Mohammad Ali Riahi

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

  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
