Question What Is The Hardness Of Shale Ceramics

Question What Is The Hardness Of Shale Ceramics

Shale is a fine grained sedimentary rock composed of mud that may include clay minerals and organic material called kerogen. Unfortunately, due to the small size of these pores, the permeability of shale is about 9 orders of magnitude less than that of a conventional sandstone reservoir.20 Nov 2014.
