It is necessary to find a method for predicting performance of fractured horizontal wells. A practical method to predict performance of a horizontal well which is hydraulically fractured and partially perforated has been proposed in this paper. Using the mathematical model presented in this paper, factors affecting performance of a hydraulically fractured horizontal well have been analyzed. Two oilfield cases from the Daqing Oilfield are analyzed using the method and presented in this paper. Calculations and analyses show that the results which are calculated using this method are consistent with the actual results from the oilfield.IntroductionUse of horizontal wells has become an effective means in oilfield development. The number of horizontal wells in the world has been continually increasing in the recent years. Methods to predict performance of horizontal wells are very important in the oil production from horizontal wells. A great deal of research concerning this area has been done in the past years.In 1987, Joshi summarized methods to predict performance of horizontal wells. Later, following the form of Vogel's equation, a method to predict performance of horizontal wells was proposed by Bendakhlia. These methods are basically based on the radial flow formula derived from Darcy's law. They are used to predict performance of horizontal wells without fractures.In 1991, Norris et al. reviewed methods for predicting performance of hydraulically fractured horizontal wells. Prediction of performance of horizontal wells with several vertical fractures was studied by Karcker et al and Soliman et al using numerical method. Mukherjee et al also proposed a method to predict performance of horizontal wells with vertical fractures using type curves. In 1989, Economides et al investigated prediction of performance of horizontal wells with lateral fractures.The methods for predicting performance of horizontal wells fall into four categories:equations deviated from Darcy's law,equations similar to Vogel's equation,reservoir numerical simulation method, andtype curve method.The methods in the first two categories are basically used in predicting performance of horizontal wells without hydraulic fractures, while that in the last two categories can be used in predicting performance of horizontal wells with hydraulic fractures.The first horizontal well drilled in the Daqing Oilfield is located in Yushuling area in the southern part of the oilfield. The horizontal well was numbered Shuping Well I. After the horizontal well was drilled, it was hydraulically fractured at three different regions. The three formed fractures were believed to be vertical. After producing oil for a few months, the well was partially re-perforated.The second horizontal well drilled in the Daqing Oilfield, numbered Maoping Well 1, was drilled in Toutai area in the southern part of the oilfield. The well was hydraulically fractured before being put into production. The four fractures were confirmed to be vertical.Based on a reformed flow resistance theory, a practical method for predicting performance of a horizontal well which is hydraulically fractured and partially perforated has been presented in this paper. The method has been successfully applied to the two hydraulically fractured horizontal wells in the Daqing Oilfield, one of which was partially perforated.P. 179 Keywords: permeability, hydraulically fractured, daqing oilfield, horizontal well, fracture length, completion installation and operations, flow resistance, directional drilling, drilling operation, upstream oil & gas Subjects: Drilling Operations, Hydraulic Fracturing, Fluid Characterization, Directional drilling, Perforating, Phase behavior and PVT measurements, Completion Installation and Operations, Completion Operations This content is only available via PDF. 1996.
