The reason for retraction stated was not complete. The correct text is as follows: This article has been retracted at the request of the Editor-in-Chief. The article contains the same research approach and results including similarmistakes as the article published in Journal of Petroleum Science and Engineering: Zhao, Y., Zhang, L., Wu, F.: Pressure Transient Analysis for Multi-fractured Horizontal Well in Shale Gas Reservoirs, 2012, vols. 90–91, pp. 31–38. This article has also been retracted http://www.sciencedirect.com/science/article/ pii/S0920410512000897.
