A study on increase the productivity optimization solution using characteristics of geomechanical property in Western Canada Shale Basin

The shale gas production has increased in Western Canada due to development of new technologies for directional drilling and hydraulic fracturing using multistage completion system. The customized development method based on geomechanical properties and brittleness index for each shale play is necessary for successful implementation of drilling and reservoir stimulation. In this study two prospective shale plays, the Montney and Liard basins in Western Canada, has selected for geomechanical properties and brittleness index from available wellbore data. As the result of this study, these two basins has high TOC, optimal geomechanical property and shows great development potential. Montney Formation in the Montney Basin and Besa River Formation in the Liard Basin show high Young’s modulus and low Poisson’s ratio, which is over 40 GPa, Young’s modulus and below 0.15, Poisson’s ratio. These rock properties of shale gas reservoirs play an important role in reservoir stimulation, especially in hydraulic fracturing.
