Fracture Interference and Refracturing of Horizontal Wells

Due to fracture interference, not all perforations can be fractured, resulting in 20% of fractures contributing 80% the total production. The extraction oil and gas also reduces production, necessitating refracturing. In this study, finite element method was used simulate multiple fracturing simultaneously stress field distribution then extracted applied a new geological model. This paper explains effect around horizontal wellbore on during refracturing old wells using temporary plugging technique. results show that initial breaking pressures are same, but as extend, inter-fracture interference increases, different extension widths. fluid is filtered into reservoir matrix after fracturing, reducing formation stress. Compared with at site, reperforating has lower pressure longer length. According hydraulic have 15 m effective influence radius external formation. Stress relief beneficial for initiation prior Reperforating combination technology, assist increasing stimulated volume achieving high stable
