In 2018, the third edition of the EAGE Workshop on Naturally Fractured Reservoirs focused on the calibration issues when characterizing and modelling these reservoirs. In this regard, the adequate use of conceptual models and appropriate multidisciplinary data was discussed in constraining our static and dynamic models.  The challenges to evaluate and capture the related uncertainties were as well exposed. For this fourth edition, we would like to dedicate the workshop to future aspects of fractured reservoirs. This will be done keeping in mind all the fundamental progress achieved during the recent past in the domains of:

-          Fracture mechanics

-          Structural history and its impact on loading and fracturing paths

-          Characterization methods for fracture distribution statistics

-          Static modelling of fractured reservoir

-          Development of fractured reservoir-dedicated flow simulation methods

Three main topics will be proposed for the technical sessions which will cover (1) the aspects of exploration and appraisal of fractured reservoirs, (2) the recent and future developments of fracture geology and (3) the links between the static and dynamic fractured reservoir models. For these three topics, an effort will be made to include all relevant input from new technologies and modeling methods, 3D visualization and 4D field monitoring, as well as the recent advances in managing uncertainties and risks. The idea will be to identify and evaluate possible new ways to overcome the current limitations of our workflows. In addition, opening these topics and discussions to novel sources of energy such as geothermal resources will be very much encouraged.
