4 Unconventional Gas Reservoir Characteristics Conventional and unconventional gases differ not by their chemical compositions (all these resources are natural gas) but rather by the geological characteristics of their reservoir rock. Permeability Challenges: Rock (matrix) permeability and porosity in unconventional reservoirs are much lower than for conventional reservoirs. 4
5 Unconventional Gas Reservoir Characteristics Low values of porosity (between 3% and 7%) Source: Investigating the Microstructure of Gas Shales by FIB/SEM Tomography & STEM Imaging Mark E. Curtis, Raymond J. Ambrose, Carl H. Sondergeld, and Chandra S. Rai University of Oklahoma Ant 5 mm Human hair 50 μm Low values of water saturation (between 10% and 50%) High values of negative water pressure (High Suction) Red blood cells 2-5 μm Atoms of silicon 10 nm 5
6 Unconventional Gas Reservoir Characteristics Conventional and unconventional gases differ not by their chemical compositions (all these resources are natural gas) but rather by the geological characteristics of their reservoir rock. Permeability Challenges: Rock (matrix) permeability and porosity in unconventional reservoirs are much lower than for conventional reservoirs. Fracturing as a solution: As a result, unconventional reservoirs only have commercial potential if the rock is fractured. Total, 2012 Natural and created fractures enhance flow potential but the location and properties of underground fractures are difficult to measure or forecast. 6
7 Hydraulic Fracturing Injection of water sand and additives under pressure. Additives protect the wellbore from corrosion and improve the effectiveness of the fracture stimulation. Strong chemical composition: chemoosmotic phenomena in Shales can be of primary importance. Source: Drilling and completing shale gas wells, horizontal drilling and well construction. New Brunswick. 7
8 State officials acknoledge that they have little information about the scale or practice of fracking in California. Los Angeles Times, April 1 st 2012 We come across new questions The Injected pressure must be greater than the horizontal stress in Shales but how greater? How does the gas permeability evolve after fracturing during gas extraction? Need to test under stress and negative water pressure (suction) control. 8
9 Geomechanical behaviour of shales A multiphysical research approach Mechanics Constitutive laws, stress redistribution, stiffness and strength variations, self sealing capacity Hydraulics Changes in saturation state, retention properties, capillary effects, hysteretical behaviours, permeability dependency on the degree of saturation, Temperature Thermal conductivity, thermal gradients, thermal fracturing Chemistry Changes in pore fluid composition Chemical weathering 9

A decrease of the air-entryvalue with suction is observed 13
