Because the pores within the shales are poorly connected or even not connected and on the other side the pores within the sandstones are much connected which allow the fluid to flow.that's why the flow rate of sandstone is greater than that of shale.

How is shale and sandstone different?

Sandstone is composed of grains of weathered rock. Limestone is the skeletal remains of countless shelled creatures. Both took many centuries and much compression to form into a sedimentary rock. Limestone was frequent in Italy (that's why there are statues from it there) whereas sandstone was frequent in central Europe which caused the existence many statues from it there. Sculptors in Italy did not suffer from lung silicosis when compared with the artists in central Europe. Also the statues in Italy did not suffer from acid rains.

What is shale gas?

Shale is a sedimentary rock that is generally formed as particles of sediment settle out in calm water. Shale can be formed in shallow inland waters or deep ocean basins. Shale rock is generally high in organic content. Once covered up by other sediments and buried over millions of years, heat and pressure begin to work on these sediments and oil and gas are formed. Some of the oil and gas may begin to migrate upwards, to layers of sandstone and porous limestone where it becomes trapped. These are considered conventional oil and gas reservoirs and shale is often the "source rock" or original source of the hydrocarbons. Natural gas and oil that occur in shale are called "unconventional". Now with new horizontal drilling and hydraulic fracturing methods it is possible to extract that oil and gas. "Unconventional" gas is quickly becoming the new norm. We have over 100 years worth (and growing) of natural gas supply in North America. In a nutshell, shale gas is standard natural gas buried much deeper and complex to extract.
