Volume fracturing can also create multiple artificial fractures perpendicular to the main fracture, improving the stimulation effect and extending the stimulation effective period. This type of fracturing method is called volume fracturing. Thus, the fracturing method in shale gas reservoirs should take natural fractures into consideration, link original micro-fractures in the reservoir, and increase the drainage area as much as possible.

Conventional fracturing usually aims to create a long single planar fracture in a reservoir, while in shale gas reservoirs, complicated fracture networks are needed. Gas contained in them is difficult to exploit thus, massive stimulation methods are needed. Shale gas reservoirs have small porosity and permeability. Maintaining these parameters requires that proppant can be distributed in fracture systems abundantly and evenly such that reservoirs can have durable fractures with good conductivity. To achieve a satisfying output, fracture dimensions matter greatly, as well as the fracture effective period. This method’s nature is to create hydraulic fractures in the reservoir, providing a flow path for oil and gas. Hydraulic fracturing is a widely used method in the development of unconventional reservoirs. The general development mode of shale gas reservoirs, as an unconventional resource, cannot yield good results.
