The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 1.4 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 1.3 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 2.2 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00034 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.46 SJR: 0.333 SNIP: 0.606 CiteScore™:: 3.1 H-Index: 31

ABSTRAKT

Modeling and numerical simulation of fluid flow in fractured-vuggy media (FVM) is a challenge due to the coexistence of multiscale void spaces filled with fluid and a complex topology configuration. An equivalent continuum approach is proposed for estimating the equivalent permeability tensor (EPT) and modeling two-phase flow with a full permeability tensor. A coupled Stokes-Darcy model is presented to estimate the EPT of a fracture-vug-media system. The operation of two-step mirror imaging is applied to any original block with asymmetric boundaries so as to form a new grid block having symmetric boundaries with periodic boundary conditions. A pretreatment approach for fractured media is developed to replace each fracture and surrounding porous media with continuous media characterized by equivalent permeability. The mixed finite element (MFE) method based on the first-order Brezzi-Douglas-Marini (BDM) space and the discontinuous Galerkin (DG) method are used to solve the pressure equation and the saturation equation for the two-phase flow problem in an equivalent region characterized by a permeability tensor. Several examples are addressed to show the feasibility, validity, and applicability of the methodology in calculating the EPT of FVM and simulating two-phase flow using a permeability tensor, and to illustrate the advantages of integrating complex flow calculations offered by the continuum model with the realism of FVM systems as captured by the discrete model.
