Abstract

The Shales are extensively encountered during various mining, tunneling, civil engineering activities and oil and gas exploration activities. The shale is a potential source rock for gas and oil exploration as well as for geothermal energy. The pore size distribution in porous rocks like shales has a great bearing on the three important and inter-related hydraulic properties viz. porosity, permeability and fluid and gas storage as well as transport capacity. The knowledge of pore size distribution of rocks is very much essential to understand the problems related with underground openings, flow patterns through reservoir, drilling of oil and gas wells, stability of deep bore wells etc. It controls the storage mechanism and reservoir fluid properties of the permeable horizons. The paper presents and discusses the results of experimental investigation conducted to understand complete pore size distribution of shales obtained through Water Vapour Adsorption Isotherms (WVAI) method as well as Mercury Intrusion Technique (MIT).
