Over the past decade,the combination of horizontal drilling and hydraulic fracturing has allowed access to large volumes of shale gas that were previously uneconomical to produce.The productivity of shale reservoir is highly dependent on the design of hydraulic fracturing treatment.In order to successfully design the treatment,a good understanding of the shale mechanical properties is necessary.This thesis purposes that proppant embedment can be divided into two mechanisms,elastic deformation an...
