Fracture development in shale and its relationship to gas accumulation
Fracture development contributes to the volumetric increase of free natural gas, desorption of adsorptive gas and the increase of total gas accumulation in shale ( Curtis, 2002, Chen et al., 2009, Li et al., 2009, Nie et al., 2009b ). Many studies have been made on the origin of fractures and their distribution in shale gas reservoirs as well ...
How Hydraulic Fracturing Works
The hydraulic fracturing process begins by injecting water to fracture the subsurface shale formation, increasing permeability and hydraulic conductivity. Sieved sand is added as a "proppant" to keep the newly fractured rock from closing back up. The sand also provides a medium for the fracturing fluid to pass through.

Experimental Evaluation of Sand Porosity in Eagle Ford Shale Fractures …
Abstract. Hydraulic fracturing is the main stimulation method used to economically produce from shale formations. The method requires the injection of a fracturing fluid at a pressure which is high enough to fracture the formation, and as a result, improves the well productivity.
