Simulation on Discrete Fracture Network Using Flexible Voronoi Gridding
… static model using Discrete Fracture Network (DFN) approach. Most work on DFN grid model up to recently has been done with Delaunay tessellations. This research proposes an alternative technique to discretize the two-dimensional DFN using Voronoi diagrams, nevertheless applying the same DFN …

Fracture Modeling and Flow Behavior in Shale Gas Reservoirs Using Discrete Fracture Networks
… good well control. Discrete Fracture Networks (DFN) model has been developed to aid is solving some of these problems experienced by using the dual continuum models. The Discrete Fracture Networks (DFN) approach involves analysis and modeling which explicitly incorporates the geometry and …

Use of hydraulic tests to identify conceptual models of heterogeneity for fractured rock aquifers
… the more realistic discrete fracture network (DFN) model, with fracture lengths distributed as a power-law is analyzed. The study is focused on the relationships among the parameters of a DFN, the flow dimension, and the regime of diffusion of pressure transients of aquifer tests (e.g., Fickian …

Stretched Exponential Decline Model as a Probabilistic and Deterministic Tool for Production Forecasting and Reserve Estimation in Oil and Gas Shales
… behavior, a series of Discrete Fracture Network (DFN) simulations were performed. Results show that at least a 3-layer model is required to reproduce the decline behavior as captured in the published SEDM parameters for Barnett Shale. Further, DFN modeling implies a large number of parameters like …

Non-destructive evaluation of laboratory scale hydraulic fracturing using acoustic emission
… in efforts to refine discrete fracture network (DFN) creation and regional damage quantification of densely fractured media. Regional damage estimations from combinations of individual microcrack analyses and AE cloud density plotting are used to investigate the usefulness of weighting cloud …

Numerical Modeling Methodology for Weak Rock Masses in Nevada gold mines
… of jointing using discrete fracture network (DFN) and rock bolts in 3DEC. Sensitivity studies were performed on over 200 time dependent numerical models to understand the effect of various rock support design parameters on different excavation sizes and depths. Rock bolt length and spacing was …

Study of mechanical properties of jointed rock mass using lattice-spring-based synthetic rock mass (LS-SRM) modeling approach
With the recent development of high-end computation technology, it is feasible to use complex numerical modeling technique such as synthetic rock mass (SRM) modeling for the characterization of mechanical properties of rock mass. However, the SRM modeling approaches that have been used to date such …
