A Numerical Simulation Study on the Kinetics of Asphaltene Particle Flocculation in a Two-dimensional Shear Flow

Hadi Bagherzadeh; Zahra Mansourpour; Bahram Dabir

Volume 8, Issue 2 , April 2019, , Pages 53-72

http://dx.doi.org/10.22050/ijogst.2018.142463.1468

Abstract
  In the current study, the kinetics of asphaltene particle flocculation is investigated under a shear flow through numerical simulation. The discrete element method (DEM) is coupled with computational fluid dynamics (CFD) to model the agglomeration and fragmentation processes. In addition, a coalescence ...  Read More

An Experimental Study of Acid Diversion by Using Gelled Acid Systems Based on Viscoelastic Surfactants: A Case Study on One of Iran Southwest Oilfields

Abdorrahman Mehri Ghahfarrokhi; Ezzatollah Kazemzadeh; Hassan Shokrollahzadeh Behbahani; Gholam Abbas Safian

Volume 8, Issue 1 , January 2019, , Pages 32-46

http://dx.doi.org/10.22050/ijogst.2018.139168.1464

Abstract
  In matrix acidizing operations, the main goal is increasing permeability. For production engineers, it is desirable that acid could be injected into whole [M.N.1] [amehri.gh2] pay zone. Sometimes, this pay zone has a long height and various sub-layers which have different permeability values. ...  Read More
