A Review of Vibrating Wire Piezometer Usage in Ultra-Low Permeability and Heterogenous Fractured Rock Environments
Event - Tucson, USAThis presentations proposes that conventional groundwater flow theory cannot explain the full range of VWP responses observed in low permeability environments. The impact of poroelasticity is likely to be greatest in the period immediately after a stress change when rapid increases and decreases in pore pressure may occur as the 3D stress field equilibrates. In the medium term, the poroelastic effects may lead to a faster rate of depressurisation in a low permeability formation.
