Faulting is typically heterogenous. Stress is often very heterogeneous over time and space, and it is accommodated over a wide range of scales. Large-scale, subsurface deformation is typically identified by the interpretation of seismic data. In addition to small-scale information from well data, sub-seismic medium-scale fractures also play a significant role: they may accommodate a significant proportion of the total strain, lateral variation may cause compartmentalised deposits and reservoirs, and fracture networks may act as conduits for diagenetic fluids.
These aspects require an analysis of location, orientation and length distribution of fault and fracture systems with a variety of methods (e.g. geophysical surveys, outcrops, well studies, field studies, simulations) for determining (a) the magnitude of deformation, (b) the strain accumulation in space and time, and (c) the processes that control them under varying kinematic constraints.
To address these topics, this session aims to discuss the (1) long- and short-term growth of fault systems at all scales, (2) the influence of pre-existing structures on the later evolution of fault zones, and (3) the impact of fault development (i.e. opening and sealing of structures) on porosity, fluid flow or other parameters of interest also for applied studies. Both natural data examples and lab studies from various disciplines may help to unravel or even predict the relationship of deformation structures at different scale lengths and during progressive deformation.
