Impact of stress dependence of elastic moduli and poroelastic constants on earth surface uplift due to injection
Samin Raziperchikolaee
Abstract:Hydromechanical models have typically assumed constant stress-independent elastic moduli to estimate, forecast, and history-match earth surface uplift. The effect of stressdependent elastic moduli and poroelastic constant (i.e., Biot coefficient) on Earth surface uplift during injection is investigated in this study. Experimental data gathered for different rock types shows that Biot coefficient and bulk modulus vary in response to Terzaghi effective stress. Stress-dependent elastic modulus was imported to the… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
