Enriched mixed finite element models for dynamic analysis of continuous and fractured porous media
Komijani, Mohammad; Gracie, Robert (Elsevier, 2019-01-01)Enriched Finite Element Models are presented to more accurately investigate the transient and wave propagation responses of continuous and fractured porous media based on mixture theory. Firstly, the Generalized Finite ... -
A non-local plasticity model of stimulated volume evolution during hydraulic fracturing
Sarvaramini, Erfan; Dusseault, Maurice B.; Komijani, Mohammad; Gracie, Robert (Elsevier, 2018-10-02)Hydraulic fracturing in naturally fractured rocks often leads to the creation of a stimulated zone in which the target rock formation is deformed and fractured by the reactivation and shear dilation of natural fractures ... -
Simulation of Hydraulic Stimulation: Acoustic Wave Emission in Fractured Porous Media Using Local and Global Partition-of-Unity Finite Element
Komijani, Mohammad (University of Waterloo, 2018-09-25)Hydraulic Fracturing (HF) is an effective stimulation process for extracting oil and gas from unconventional low-permeable reservoirs. The process is conducted by injecting high-pressure fluids into the ground to generate ... -
Simulation of Induced Acoustic Emission in Fractured Porous Media
Komijani, Mohammad; Gracie, Robert; Sarvaramini, Erfan (Elsevier, 2019-04-01)Acoustic/microseismic Emissions (AE) in naturally fractured porous media are the result of local instability along internal interfaces and the sudden release of strain energy stored in the rock matrix. This rapid release ...
