RETRACTED: Finite element analysis method for horizontal well hydraulic fracturing

This article has been retracted: please see Elsevier Policy on Article Withdrawal (http://www.elsevier.com/locate/withdrawalpolicy).This article has been retracted at the request of the editor as it is reproduces significant parts of text that have already been published in 'Three-dimensional finite element simulation and parametric study for horizontal well hydraulic fracture', G.M. Zhang, H. Liu, J. Zhang, H.A. Wu, X.X. Wang, J. Petrol. Sci. Eng., 72 (2010) 310–317, http://dx.doi.org/10.1016/j.petrol.2010.03.032. The amount of new research presented in this paper is not sufficient to justify a separate publication. The authors would like to apologise to the scientific community for this oversight.
