New Technique for Calculation of Well Flowing Performance in Hydraulically Fractured Wells

One of the main concerns for reservoir engineers is prediction of future well performance. In hydraulically fractured wells flowing parameters completely change the governing equations of fluid flow through the reservoir and wellbore. Since the purpose of hydraulic fracturing is reduction of skin effect, this parameter plays the most important role in the future well performance. This paper introduces a new method for prediction of hydraulically fractured wells performance. This technique is based on using a new approach for skin effect parameter in hydraulically fractured wells. This method uses the concept of Part’s fracture relative capacity, without requiring knowing fracture and reservoir permeability or fracturing width. In this approach to convergence the fracture skin effect have derived a relation between fracture relative capacity and dimensionless fracture conductivity by using Cinco-Ley and Samaniego method. A program had been prepared to calculation of numerical equations governing on well flowing performance in the case of hydraulically fractured well through this study. At the end, this approach and developed code have been applied to the several fractured well fine grid black-oil simulation of a real oil reservoir. Finally, the simulation study confirmed the results of the proposed model and there was a reasonable agreement between the obtained results of proposed model and numerical simulator.
