Analysis of Parameters Influencing Shale Gas/Shale Oil Reservoir Complex Fractures Network Construction

Bastos Fernandes Fernando* and Martins Barbosa Braga

Shales reservoirs have a high degree of anisotropy due to the presence of natural fractures (NFs) and also the orientation of beddings. Thus, hydraulically induced fractures (HFs) interact with natural fractures and build a network of fractures with complex morphology. The construction of a network of fractures significantly increases the conductivity of the formation, as it connects previously isolated fractures and pores, thus increasing the productivity index of the wells and providing greater economic viability in the shale gas/oil reservoir designs. This work presents the main parameters that have influence on the fractures generated in shales, aiming to understand their effects in shale rock and avoid problems in of the hydraulic fracturing design.
