“…We therefore abandoned this attempt and instead used permeability values from the literature from similar but higher-permeable lithotypes. The relationship between our own permeability measurements and those used in our simulations is shown in Figure 4c; permeability inputs were chosen from a range extending across values reported by Rath et al (2011) and Antonellini et al (2014b). In addition to alleviating the said practical simulation problems, our use of a wider range of permeabilities from the literature expands the general relevance of our models (i.e.…”

“…Within porous granular carbonate rocks there is a growing body of documentation covering the structure, mechanics and kinematics of natural deformation bands (Tondi et al 2006Tondi 2007;Antonellini et al 2008Antonellini et al , 2014bAgosta et al 2009;Cilona et al 2012;Rustichelli et al 2012) as well as laboratoryinduced deformation bands (Baxevanis et al 2006;Baud et al 2009;Vajdova et al 2010;Zhu et al 2010;Cilona et al 2012Cilona et al , 2014Ji et al 2015). Studies reporting permeability, on the other hand, are scarce but suggest that deformation bands in carbonate rocks are associated with a permeability reduction of 1 -3 orders of magnitude relative to host rock (Rath et al 2011;Antonellini et al 2014a, b;Tondi et al 2016).…”

We investigate the permeability and flow effects of deformation bands in porous granular carbonate rocks in Malta and use results from flow simulations to discuss the practical implications of deformation bands in carbonate and siliciclastic reservoirs rocks in general. Image-and laboratory-based analyses of deformation bands show permeabilities that are 1 -2 orders of magnitude lower than the adjacent host rocks. Small-scale outcrop-based flow models (1 × 1 m) focus on the effect of deformation band on flow at the scale of individual bands. Two-phase flow simulations (water displacing oil) show that at the local scale a decrease in deformation band permeability led to increasing flow complexity, reduced and irregular waterfront propagation and reduction in sweep efficiency. A reduction in host rock permeability is associated with increased sensitivity to deformation bands. In low-permeable host rocks, a single magnitude-order reduction of deformation band permeability significantly delays flow, whereas in higher-permeable host rocks the effect is less pronounced. Hence, in some cases, deformation bands may represent a significant impediment to flow already when they are only 1 -2 orders of magnitude less permeable than host rock. Consequently, deformation bands may have greater practical implications than previously thought, particularly in reservoir rocks with moderate to low host rock permeability.

“…Furthermore, Antonellini et al (2014b) highlight a different micro-mechanism of deformation in carbonate rocks composed of soft micrite peloids, namely soft plastic deformation and subsequent smearing of the peloids, where grain crushing and pressure solution are subordinate micromechanisms. This plastic smearing is interpreted by Antonellini et al (2014b) to occur due to the intragranular microporosity present in the peloids. Second, cataclasis, as a mechanism for strain accommodation in carbonate deformation bands, appears to be widespread at shallow burial depths (e.g.…”

“…Natural examples of these bands have been reported since the mid-2000s Micarelli et al, 2006;Tondi et al, 2006). Further studies have followed, including experimental work (Baxevanis et al, 2006;Baud et al, 2009;Vajdova et al, 2010;Zhu et al, 2010;Cilona et al, 2012Cilona et al, , 2014Ji et al, 2015) and field-based studies that document deformation bands predominantly in carbonate grainstones (Antonellini et al, 2008;Agosta et al, 2009;Cilona et al, 2012;Rustichelli et al, 2012;Tondi et al, 2012;Antonellini et al, 2014b), and recently also in chalk (Wennberg et al, 2013).…”

“…However, there are also studies that report non-cataclastic and cataclastic deformation bands in porous carbonate rocks where evidence for pressure-solution processes is absent (Rath et al, 2011).

a b s t r a c tDeformation bands in porous sandstones have been extensively studied for four decades, whereas comparatively less is known about deformation bands in porous carbonate rocks, particularly in extensional settings. Here, we investigate porous grainstones of the Globigerina Limestone Formation in Malta, which contain several types of deformation bands in the hangingwall of the Maghlaq Fault: (i) bed-parallel pure compaction bands (PCB); (ii) pressure solution-dominated compactive shear bands (SCSB) and iii) cataclasis-dominated compactive shear bands (CCSB). Geometric and kinematic analyses show that the bands formed sequentially in the hangingwall of the evolving Maghlaq growth fault. PCBs formed first due to fault-controlled subsidence and vertical loading; a (semi-)tectonic control on PCB formation is thus documented for the first time in an extensional setting. Pressure solution (dominating SCSBs) and cataclasis (dominating CCSBs) appear to have operated separately, and not in concert. Our findings therefore suggest that, in some carbonate rocks, cataclasis within deformation bands may develop irrespective of whether pressure solution processes are involved. We suggest this may be related to stress state, and that whereas pressure solution is a significant facilitator of grain size reduction in contractional settings, grain size reduction within deformation bands in extensional settings is less dependent on pressure solution processes.
