“…It is generally accepted that faultrelated folding can be described by three end-member geometries: detachment folds, fault-bend folds, and fault-propagation folds (e.g. De Sitter, 1956;Dahlstrom, 1969;Suppe, 1983;Suppe andMedwedeff, 1984, 1990;Jamison, 1987;Chester and Chester, 1990;Mitra, 1990Mitra, , 1992Mitra, , 2003Erslev, 1991;Fisher et al, 1992;Epard and Groshong, 1995;Poblet and McClay, 1996;Storti and Salvini, 1996;Hardy and Ford, 1997;Allmendinger, 1998;Suppe et al, 2004;Hardy and Finch, 2007;Albertz and Lingrey, 2012). Such three end-members, however, often represent different stages in the evolution of the same structure (e.g., Storti et al, 1997).…”

“…The consequences of these parameters can then be tested using an appropriate loading arrangement (e.g. Hardy & Finch 2007). Spence & Finch (2014) use discrete element models to investigate the effects of mechanical heterogeneity at layer interfaces, caused by the presence of stratified chert nodules, on the development of fracture networks within carbonate sedimentary cycles.…”

Naturally fractured reservoirs, within which porosity, permeability pathways and/or impermeable barriers formed by the fracture network interact with those of the host rock matrix to influence fluid flow and storage, can occur in sedimentary, igneous and metamorphic rocks. These reservoirs constitute a substantial percentage of remaining hydrocarbon resources; they create exploration targets in otherwise impermeable rocks, including under-explored crystalline basement, and they can be used as geological stores for anthropogenic carbon dioxide. Their complex fluid flow behaviour during production has traditionally proved difficult to predict, causing a large degree of uncertainty in reservoir development. The applied study of naturally fractured reservoirs seeks to constrain this uncertainty and maximize production by developing new understanding, and is necessarily a broad, integrated, interdisciplinary topic. Some of the methods, challenges and advances in characterizing the interplay of rock matrix and fracture networks relevant to fluid flow and hydrocarbon recovery are reviewed and discussed via the contributions in this volume.Global estimates of conventional hydrocarbon resources are typically subdivided based on lithological reservoir types for example, carbonate or siliciclastic (e.g. Roehl & Choquette 1985). However, many of these sedimentary rock reservoirs may contain fractures to a greater or lesser degree. The recent boom of unconventional reservoirs highlights once again the key role that natural fractures can play in helping production of fluids. It also requires an improved understanding of the geology and physics of natural fracture networks to meet public expectations regarding safety issues. Moreover, fracture networks can be present in otherwise impermeable crystalline basement rocks (e.g. Sanders et al. 2003;Murray & Montgomery 2012;Slightam 2012) and igneous intrusions (e.g. Gudmundsson & Løtveit 2012), also allowing these rocks to form potential fractured reservoirs. Historically, fractured crystalline basement rocks have been under-explored as potential hydrocarbon reservoirs. Naturally fractured reservoirs constitute a substantial percentage of remaining hydrocarbon resources. Naturally fractured reservoirsA reservoir fracture is a general term used to describe a 'naturally occurring macroscopic planar discontinuity in rock due to deformation, or physical diagenesis' (Nelson 2001). Reservoir fractures encompass both extensional ( joints) and shear (faults) structures. Fractures formed by brittle tectonic deformation are the most common focus for studies of naturally fractured reservoirs. However, reservoir fractures may also include structures that formed by desiccation (e.g. shrinkage cracks) and syneresis (e.g. chickenwire texture) in sediments, and structures that formed by thermal , as used here. Naturally fractured reservoirs are generally defined as such when the fracture network has a significant influence on fluid flow in the reservoir such that: (1) the fracture networ...

“…The difficulty of the numerical approaches is that the solution search occurs close to or beyond the local conditions of shear banding for which the strain is localized on a length scale not resolved by the discretization. New algorithms are required to adapt this discretization (Braun & Sambridge 1994) or a characteristic length should be included, as with the discrete-element technique (Hardy & Finch 2007).…”

It is proposed to complement the numerous geometrical constructions of fault-related folds relevant to fold-and-thrust belts by the introduction of mechanical equilibrium and of the rock limited strength to discriminate between various deformation scenarios. The theory used to support this statement is the maximum strength theorem that is related to the kinematic approach of limit analysis known in soil mechanics. The classical geometrical construction of the fault-propagation fold (FPF) is proposed for illustration of our claim. The FPF is composed of a kink fold with migrating axial surfaces ahead of the region where the ramp propagates. These surfaces are assigned frictional properties and their friction angle is found to be small compared with the usual bulk friction angle to ensure the full development of the FPF, a first scenario. For larger values of the axial surface friction angle, this development during overall shortening is arrested by the onset of fault breaking through the front limb, a second scenario. The amount of shortening at the transition from folding to break-through faulting is established.
