Abstract
  Complexity of geomaterial’s behavior is beyond the capabilities of conventional numerical methods alone for realistically model rock structures. Coupling of numerical methods can make the numerical modeling more realistic. Discontinuous Deformation Analysis (DDA) and Displacement Discontinuous ...  Read More

Cavity Growth in Underground Coal Gasification Method by Considering Cleat Length and Inclination of Coal with Elasto-Brittle Behavior

M.R. Shahbazi; M. Najafi; M. Fatehi Marji; A. Abdollahipour

Volume 13, Issue 2 , April 2022, , Pages 607-625

https://doi.org/10.22044/jme.2022.11906.2183

Abstract
  The in-situ coal is converted to the synthetic gas in the process of underground coal gasification (UCG).  In order to increase the rate of in-situ coal combustion in the UCG process, the contact surfaces between the steam, heat, and coal fractures should be raised. Therefore, the number of secondary ...  Read More

Compressive Failure Analyses of Rock-Like Materials by Experimental and Numerical Methods

M. Davood Yavari; H. Haeri; V. Sarfarazi; M. Fatehi Marji; H. A. Lazemi

Volume 12, Issue 3 , July 2021, , Pages 769-783

https://doi.org/10.22044/jme.2021.10819.2052

Abstract
  Investigating the crack propagation mechanism is of paramount importance in analyzing the failure process of most materials. This process may be exposed during each kind of loading on the materials. In this work, the cracking mechanism in rock-like materials is studied using the numerical methods and ...  Read More

Behavior of a hydraulic fracture in permeable formations

A. Abdollahipour; M. Fatehi Marji; H. Soltanian; E. A. Kazemzadeh

Volume 9, Issue 4 , October 2018, , Pages 893-904

https://doi.org/10.22044/jme.2018.6129.1428

Abstract
  The permeability and coupled behavior of pore pressure and deformations play an important role in hydraulic fracturing (HF) modeling. In this work, a poroelastic displacement discontinuity method is used to study the permeability effect on the HF development in various formation permeabilities. The numerical ...  Read More

Numerical investigation of effect of crack geometrical parameters on hydraulic fracturing process of hydrocarbon reservoirs

A. Abdollahipour; M. Fatehi Marji; A. R. Yarahmadi Bafghi; J. Gholamnejad

Volume 7, Issue 2 , July 2016, , Pages 205-214

https://doi.org/10.22044/jme.2016.532

Abstract
  Hydraulic fracturing (HF), as a stimulation technique in petroleum engineering, has made possible the oil production from reservoirs with very low permeability. The combination of horizontal drilling and multiple HF with various perforation angles has been widely used to stimulate oil reservoirs for ...  Read More
