Hydraulic fracturing is an important technique used for developing shale gas reservoirs. Compared with multistage consecutive fracturing, multistage alternative fracturing is a more challenging technique due to the current limitations of downhole tools. This paper simulates multistage fracturing and compares the fracture geometries and fluid distributions of consecutive and alternative fracturing. It is found that simultaneous propagation of multiple fractures results in their unequal stimulations. Some perforations do not contribute to well production because their fractures are restrained. Alternative fracturing tends to create more uniform length fractures and thus achieves a greater stimulated reservoir volume than that of consecutive fracturing.
