“…Although there are documented examples of carbonate-hosted fault zones acting as barriers to fluid flow (e.g. Bockel-Rebelle et al, 2004;Birkle and Angulo, 2005;Vega Riveros et al, 2011;Corona et al, 2012), their impact on flow is poorly understood, despite the global importance of carbonate reservoirs in hydrocarbon reserves; around 60% of global oil reserves and 40% of global gas reserves are stored in carbonates (Schlumberger, 2007). Past research into the sealing potential of faults has been primarily directed towards siliciclastic hydrocarbon reservoirs (e.g.…”

“…However, over the last decade, many more investigations of fault zones in carbonates have emerged, encouraged by the high-resolution seismic imaging of carbonate reservoirs that revealed large populations of subtle faults. For example, Corona et al (2012) discussed dynamic data for multiple fault zones within the Zechstein carbonates, representing a rare quantification of flow properties in subsurface fault zones with sufficient data to support broader inferences. Other large datasets of fault damage zones in outcrops in the NW German Basin also enabled Reyer et al (2012) to develop rules of thumb for the mechanical behaviour of, and fluid flow in, carbonate faults in a region that might be usefully transferred to the subsurface (e.g.…”

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.

Toward the creation of models to predict static and dynamic fault-seal potential in carbonates

In contrast to faults in clastic reservoirs, rules to predict the exploration and production timescale fault-seal potential in carbonates are lacking. This paper provides a summary of carbonate reservoirs with cross-fault column height differences that represent examples of apparent static fault seal, and a summary of observed examples of dynamic fault seal in carbonate reservoirs and aquifers. These include cross-fault differences in water table depths across carbonate–carbonate juxtapositions, cross-fault pressure differences in carbonate aquifers separated by faults, production-induced cross-fault pressure differences in carbonate hydrocarbon reservoirs, sealing behaviour of faults in carbonate reservoirs inferred from well tests, and examples of low fault transmissibilities from history-matching exercises from carbonate reservoirs. This paper also documents the range of compositions of fault rocks in carbonates and the range of permeabilities that have been reported from low-permeability fault cores in carbonate fault zones, as well as the implications of the observed range of fault permeabilities in carbonates for sealing behaviours. The purpose of this paper is not to argue that every fault in a carbonate reservoir will seal or will even be capable of sealing. There are, however, enough examples of faults in carbonates that are sealing in a dynamic sense, and in a static sense, that the topic of carbonate fault seal should warrant much more study. Creation of predictive models will ultimately require a considerable amount of subsurface data, but these models should be created.
