HEF splits the computations into fine scale and coarse scale. Fine scale solves analytically for the matrix-fracture flux exchange parameter. Coarse scale solves for the properties of the entire system. In literature, fractures were assumed to be either vertical or horizontal for simplification (Warren and Root, 1963). Matrix-fracture flux exchange parameter was given few equations built on that assumption (Kazemi, 1968; Lemonnier and Bourbiaux, 2010). However, such simplified cases do not apply directly for actual random fracture shapes, directions, orientations …etc. This paper shows that the HEF fine scale analytic solution (Amir and Sun, 2016) generates the flux exchange parameter found in literature for vertical and horizontal fracture cases. For other fracture cases, the flux exchange parameter changes according to the angle, slop, direction, … etc. This conclusion rises from the analysis of both: the Discrete Fracture Network (DFN) and the HEF schemes. The behavior of both schemes is analyzed with exactly similar fracture conditions and the results are shown and discussed. Then, a generalization is illustrated for any slightly compressible single-phase fluid within fractured porous media and its results are discussed. dc.description.sponsorship King Abdullah University of Science and Technology (KAUST) funding supported the research reported in this publication. dc.publisher Elsevier BV dc.relation.url http://www.sciencedirect.com/science/article/pii/S1877050917305835 dc.rights Under a Creative Commons license dc.rights.uri http://creativecommons.org/licenses/by-nc-nd/4.0/ dc.subject Discrete Fracture Network (DFN) dc.subject two-scale dc.subject hybrid method dc.subject matrix-fracture flux exchange dc.title Reduced Fracture Finite Element Model Analysis of an Efficient Two-Scale Hybrid Embedded Fracture Model dc.type Article dc.contributor.department Computational Transport Phenomena Lab dc.contributor.department Earth Science and Engineering Program dc.contributor.department Physical Science and Engineering (PSE) Division dc.identifier.journal Procedia Computer Science dc.eprint.version Publisher's Version/PDF dc.contributor.institution Xiamen University, School of Mathematical Sciences, Fujian Provincial Key Laboratory on Mathematical Modeling and High Performance Scientific Computing, Fujian, 361005, China kaust.person Amir, Sahar Z. kaust.person Sun, Shuyu refterms.dateFOA 2018-06-13T14:37:17Z dc.date.published-online 2017-06-09 dc.date.published-print 2017
