Paper Number: ARMA-2021-1655
... ABSTRACT: It is critical to smoothly and efficiently couple fracture complexities from fracture model with reservoir model in shale reservoirs with complex natural fractures. In this study, an efficient EDFM (embedded discrete fracture model) method was applied and tested. First, the fracture...

... to obtain fracture complexity in the absence of any reservoir heterogeneity. We show that competing fracture propagation can induce a heterogeneous stress state in the rock. This new heterogeneous stress state is induced by the spatial variation of the stress shadow of the propagating fractures. Multiple...

... sandstones (from He-8, Shan-1, and Chang-7 formations in Ordos Basin, China) by using slickwater, liquid CO 2 (L-CO 2 ), and supercritical CO 2 (SC-CO 2 ). Experimental results show that L-CO 2 and SC-CO 2 can improve the fracture complexity to a limited extent in homogenous tight sandstones (He-8...

... fracture complexity. The propagation of fractures is modeled using a phase field method. This method allows the handling of kinking, branching, and merging of induced fractures with preexisting fractures based on an energy minimization approach. The study emphasizes the importance of near well...

.... These measurements of propped and unpropped fracture conductivity were compared to corresponding measurements on small samples. Results show that the larger fractures, whether propped or unpropped, retain higher fracture conductivity with increasing stress. We also observe substantial fracture complexity associated...
