“…When using XFEM for fluid infiltrated medium, a proper enrichment needs to be implemented to reproduce the pore-pressure variation in the solid matrix associated with the fracture (discontinuity in the pressure gradient normal to the fracture). Different schemes have been proposed (Mohammadnejad and Khoei, 2013a;Faivre et al, 2016;Meschke and Leonhart, 2015). The lack of consistent benchmarking and convergence studies renders the discussion on the efficiency and robustness of these different schemes rather difficult.…”

Utilization of hydraulic-fracturing technology is dramatically increasing in exploitation of natural gas extraction. However the prediction of the configuration of propagated hydraulic fracture is extremely challenging. This paper presents a numerical method of obtaining the configuration of the propagated hydraulic fracture into discrete natural fracture network system. The method is developed on the basis of weighted fracture which is derived in combination of Dijkstra's algorithm energy theory and vector method. Numerical results along with experimental data demonstrated that proposed method is capable of predicting the propagated hydraulic fracture configuration reasonably with high computation efficiency. Sensitivity analysis reveals a number of interesting observation results: the shortest path weight value decreases with increasing of fracture density and length, and increases with increasing of the angle between fractures to the maximum principal stress direction. Our method is helpful for evaluating the complexity of the discrete fracture network, to obtain the extension direction of the fracture.

“…Jin Yan, et al [13] analyzed the effects of salutatory barriers on hydraulic fracture propagation, but no further results were presented. Recently, numerical methods have been widely used to solve the hydraulic fracture problem and many related studies can be found in the literature [14][15][16].…”

Abstract. Hydraulic fracturing technology is widely used in most oil-water wells to improve production. However, the mechanism of fracturing in a reservoir with inclusion fissures is still unclear. In this study, a theoretical model was developed to determine the stress distribution during hydraulic fracturing. The line inclusion fissure was regarded as a thin bar and the stress around the artificial fracture, which is affected by a single line inclusion, was determined using the Eshelby equivalent inclusion theory. Stress intensity factors at the tip of both the artificial fracture and the inclusion were achieved, and initiation of the fracture was predicted. Furthermore, to validate the theoretical model, refracturing experiments were performed on a large-scale tri-axial system. The results showed that the defects reduce the intensity of the rock, which introduces the possibility that more complex fractures emerge in the reservoir. The results also showed that the fracture direction is governed by far-field stress. The obtained conclusions are helpful to better understand the mechanism of hydraulic fracturing in reservoirs.
