Structural analyses and fracture network characterisation: Seven pillars of wisdom

We suggest that any structural study be tailored to suit the desired outcome and that this scheme of analysis types should be used as a basis for the development of workflows, for the design of research projects and for testing hypotheses. For example, prediction of fluid flow through a fracture network must begin with the basic geological description of fracture types. Basic geological descriptions should be followed by measuring their geometries and topologies, understanding their age relationships, kinematic and mechanics, and developing a realistic, data-led model for related fluid flow. Missing steps can lead to fundamentally flawed interpretations.
