On the crack propagation modeling of hydraulic fracturing by a hybridized displacement discontinuity/boundary collocation method

M. Behnia; K. Goshtasbi; M. Fatehi Marji; A. Golshani

Volume 2, Issue 1 , January 2011

http://dx.doi.org/10.22044/jme.2012.15

Abstract
  Numerical methods such as boundary element and finite element methods are widely used for the stress analysis in solid mechanics. This study presents boundary element method based on the displacement discontinuity formulation to solve general problems of interaction between hydraulic fracturing and discontinuities. ...  Read More

Pollution problems in the metallurgical industry: A review

F. Habashi

Volume 2, Issue 1 , January 2011, Pages 17-26

http://dx.doi.org/10.22044/jme.2012.16

Abstract
  Processing of minerals and production of metals has increased greatly in recent years. As a result, the quantities of waste material and pollutants have also increased. In many cases technology has changed to cope with the problem. Processes have been either modified to decrease emissions, or replaced ...  Read More

Support vector regression for prediction of gas reservoirs permeability

R. Gholami; A. Moradzadeh

Volume 2, Issue 1 , January 2011

http://dx.doi.org/10.22044/jme.2012.18

Abstract
  Reservoir permeability is a critical parameter for characterization of the hydrocarbon reservoirs. In fact, determination of permeability is a crucial task in reserve estimation, production and development. Traditional methods for permeability prediction are well log and core data analysis which are ...  Read More

Developing a method for identification of net zones using log data and diffusivity equation

P. Masoudi; B. Tokhmechi; A. Zahedi; M. Ansari Jafari

Volume 2, Issue 1 , January 2011

http://dx.doi.org/10.22044/jme.2012.19

Abstract
  Distinguishing productive zones of a drilled oil well plays a very important role for petroleum engineers to decide where to perforate to produce oil. Conventionally, net pay zones are determined by applying a set of cut-offs on perophysical logs. As a result, the conventional method finds productive ...  Read More
