Influence of deformation-band fault damage zone on reservoir performance

Abstract: Access to 3D descriptions of fault zone architectures and recent development of modeling techniques allowing explicit rendering of these features in reservoir models, provide a new tool for detailed implementation of fault zone properties. Our aim is to assess how explicit rendering of fault zone architecture and properties affects performance of fluid flow simulation models. The test models use a fault with a maximum 100 m displacement and a fault damage zone with petrophysical heterogeneity caused by the pre… Show more

“…However, fault segments at a fine scale are still important, because damage zones show similar geometries across a wide range of scales (mm-km) [37,38], and their spatial distribution firmly depends on the segment geometries. Only considering damage zones on a large scale underestimates complex structures on a fine scale and neglects their impact on the fluid flow [39][40][41]. Precise images of the architectural elements of faults at depth are difficult to obtain by seismic acquisition and imaging techniques.…”

“…Accurate site characterization and understanding of the impact of geology on fluid flow in the subsurface is essential for reservoir management of CO 2 geologic storage projects (Chadwick et al, 2004;Cowton et al, 2018;Edlmann et al, 2016;Eiken et al, 2011;Hansen et al, 2013) and enhanced oil recovery operations (Ader and Stein, 1984;Malik and Islam, 2000;Mezzomo et al, 2001;Sheng, 2013). Small-scale heterogeneities, on the scale of millimeters to centimeters, have been demonstrated to have a strong impact on fluid flow at the reservoir scale (Gershenzon et al, 2014;Krevor et al, 2015;Li and Benson, 2015;Lunn et al, 2008;Qu et al, 2017;Rotevatn and Fossen, 2011;Saadatpoor et al, 2010).…”

“…While several studies have highlighted the fact that deformation bands negatively affect fluid flow (Naruk et al, 2009;Qu et al, 2017;Romano et al, 2020;Rotevatn and Fossen, 2011;Rotevatn et al, 2017;Shipton, et al, 2005;Wilkins et al, 2019), the extent of reservoir compartmentalization induced by deformation bands is unclear. Reservoir compartmentalization happens when fluids are segregated into several saturation/pressure regions due to the presence of barriers.…”

“…Liu et al [27] proposed a performance degradation feature extraction method based on mathematical morphological gradient spectrum entropy. Qu et al [28] investigated the influence of deformation-band damage zone on reservoir performance in the presence of different fault core transmissibility multipliers. Chen et al [29] proposed a novel model-deep inception nets with atrous convolution-to extract common features shared by both kinds of data, because the differences between the artificial one and the natural one baffle the learning machine.…”
