title = "Time dependent behaviour of fluids filled geomaterials: Application to reservoir formations",
abstract = "In this paper a rate dependent model for geomaterials saturated by a mixture of immiscible fluids is presented. The proposed constitutive law generalizes the isotach approach to the elastoplastic strain hardening based constitutive laws for partially saturated soils. The formulation encompasses rate and creep effects together with suction dependency on creep. Some perspectives about the constitutive modelling of time-dependent behaviour of geomaterials saturated by a single or two fluids, including soft rocks are proposed. Practical applications include modelling of underground carries submitted to humidity changes, oil reservoir formations or geological storage of CO2. In this study, the model formulation is presented and numerical predictions are compared with available experimental results on oil reservoir chalk.",
