The DMX Protocol, developed over a period of 15 years, constitutes a major technological breakthrough in the modeling of faulted and fractures reservoirs. It includes new features such as fracture interaction (IXTV truncations & termination and cross cutting in 3d space), all based on newly designed collision algorithms and fracture propagation principles. It furthermore permits modelling at any scale range in 3d of unlimited fracture shapes, specific fracture morphology, and fracture aperture types. It integrates classical geological/geomechanical drivers such as stress ellipse, fault zones with 3d slip vectors, and fold models (axial plane, fold axis and bedding orientation conditioning), geological assembly modelling (joint spacing, set dependency, offset/faulting), and probabilistic conditioning of any of the parameters and drivers. The FMX protocol is a set of tools that analyses datasets for mathematical characterizations of parameter distributions such as size, spacing, orientation and truncations (e.g. Normal, Power Law, LogNormal). These tools are linked to different type of Data Driven Modeling technologies, already presented during the last 25 years, both in 2d and 3d (FPDM statistical mapping of orientation and density, 3d deterministic surface fitting) in order to obtain realistic 2d and 3d fracture and fault networks directly based and linked to the observations. In this presentation these exiting new technologies will be highlighted with examples, and two applications will be described in more detail: Integrated surface-subsurface studies during exploration and appraisal of tight Palaeozoic Gas reservoirs in Algeria, and surface studies on analogues of the Triassic Khuff dolomites reservoirs in the UAE (Ras Al Khaimah area). The technology provides outputs like effective porosity, permeability, connectivity and storability, upscaling parameters for dynamic reservoir simulation and transport to discrete flow models, and parameters for the optimisation of horizontal and deviated wells and frac tests. Proven and potential applications are in Conventional and Unconventional E&P, Groundwater Management, Civil Engineering – Geothermal Energy Generation, CCS Carbon Capture and Storage, and Nuclear Waste Management.
