Abstract
In order to enhance the understanding of reservoir architecture, the organisation of permeability tensor a various scales, and the response of fluid flows to reservoir heterogeneity, a new and disruptive way of addressing the use of analogues in geosciences and reservoir has been developed. Through a multi-physics and multi-scales characterization of an analogue groundwater reservoir, the assessment of reservoir at any scale and the evaluation of the reservoir behaviour is considerably improved. The combination of data acquired on outcrops, within wells and in short spacing interwells volumes enable to get measurements in volumes never assessed in oil and gas fields. The detailed geological description of outcrops and cores combined with petrophysical data, high resolution geophysics, hydraulic data and hydromechanical measurements leads to an exhaustive reservoir characterisation and a comprehensive evolution of the permeability tensor over increasing volumes. Geophysical and hydraulic inversions contribute to an iterative enhanced description of reservoir heterogeneity and equivalent permeability at various scales. It gives drivers for a confident extrapolation of reservoir properties during modelling.
