Fractured Basement – DFN Modelling in an Integrated Geologically Consistent History Matching Approach

The geomodel of a fractured basement reservoir model is realized in order to integrate all available data, particularly 3D seismic cubes and attributes, and flowmeter logs. Considering the geological context of this field, a particular attention has been given to capture its flow behaviour. To do so, it has been necessary to use a dual media approach, thus to characterize and model the matrix and the fracture network. We intend to describe the implemented approach. Starting with the description of the generated Discrete Fracture Network DFN calibrated towards dynamic data which allows reducing the uncertainty on key production characteristics of the field and production forecasts for the field development. Focus will be set on the synergies arising while combining leading edge fracture modelling techniques and uncertainties management through history matching.
