“…In the damage zone, porosity and permeability are expected to increase and are controlled by connectivity and anisotropy of fracture networks (Agosta et al 2010;Billi 2005b) and/or breccia zones (e.g. Billi 2005a; Hausegger et al 2010;Tarasewicz et al 2005).…”

This study presents a comparative, field-based hydrogeological characterization of exhumed, inactive fault zones in low-porosity Triassic dolostones and limestones of the Hochschwab massif, a carbonate unit of high economic importance supplying 60 % of the drinking water of Austria's capital, Vienna. Cataclastic rocks and sheared, strongly cemented breccias form low-permeability (<1 mD) domains along faults. Fractured rocks with fracture densities varying by a factor of 10 and fracture porosities varying by a factor of 3, and dilation breccias with average porosities >3 % and permeabilities >1,000 mD form high-permeability domains. With respect to fault-zone architecture and rock content, which is demonstrated to be different for dolostone and limestone, four types of faults are presented. Faults with single-stranded minor fault cores, faults with single-stranded permeable fault cores, and faults with multiple-stranded fault cores are seen as conduits. Faults with single-stranded impermeable fault cores are seen as conduit-barrier systems. Karstic carbonate dissolution occurs along fault cores in limestones and, to a lesser degree, dolostones and creates superposed highpermeability conduits. On a regional scale, faults of a particular deformation event have to be viewed as forming a network of flow conduits directing recharge more or less rapidly towards the water table and the springs. Sections of impermeable fault cores only very locally have the potential to create barriers.

“…Static and dynamic domains defined by separate model components can be radically different from those defined by a knowledge of: (a) the combined impacts of geological elements on flow in a given region v. their effects modelled separately and coupled across different grids; and (b) the significance of knowing the relative impacts of geological elements on flow at different scales (in a given combination) and to determine which ones matter. There is certainly value in individual studies, such as in-depth investigations of carbonate fault zones (Ferrill et al 2011), studies of mechanisms, environment and timing related to fracture populations (Amrouch et al 2010;Jeanne et al 2012), and constraints on reservoir architecture, physical properties and fluid systems (Hausegger et al 2010;Wolf et al 2012) that yield valuable insights into processes and location-specific factors. Similarly, the last few years have seen a continuing publication of diagenetic studies in outcrops (López-Horgue et al 2010;Maliva et al 2011;Palermo et al 2012) as well as in the subsurface (Morad et al 2012;Machel 2010).…”

The introduction reviews topics relevant to the fundamental controls on fluid flow in carbonate reservoirs and to the prediction of reservoir performance. The review provides research and industry contexts for papers in this volume only. A discussion of global context and frameworks emphasizes the value yet to be captured from compare and contrast studies. Multidisciplinary efforts highlight the importance of greater integration of sedimentology, diagenesis and structural geology. Developments in analytical and experimental methods, stimulated by advances in the materials sciences, support new insights into fundamental (pore-scale) processes in carbonate rocks. Subsurface imaging methods relevant to the delineation of heterogeneities in carbonates highlight techniques that serve to decrease the gap between seismically resolvable features and well-scale measurements. Methods to fuse geological information across scales are advancing through multiscale integration and proxies. A surge in computational power over the last two decades has been accompanied by developments in computational methods and algorithms. Developments related to visualization and data interaction support stronger geoscience-engineering collaborations. High-resolution and real-time monitoring of the subsurface are driving novel sensing capabilities and growing interest in data mining and analytics. Together, these offer an exciting opportunity to learn more about the fundamental fluid-flow processes in carbonate reservoirs at the interwell scale.
