Non-destructive evaluation of laboratory scale hydraulic fracturing using acoustic emission
… to develop techniques to characterize hydraulic fractures and fracturing processes using acoustic emission monitoring based on laboratory scale hydraulic fracturing experiments. Individual microcrack AE source characterization is performed to understand the failure mechanisms associated with …

Numerical Modeling Methodology for Weak Rock Masses in Nevada gold mines
Many Nevada gold deposits are found in highly fractured and faulted host rock with RMR ranging from 10 to 50. Various ground control design issues in weak rock masses are faced by most underground mines operating in Nevada. Numerical models complement field observations, instrumentation techniques, …

Simulation on Discrete Fracture Network Using Flexible Voronoi Gridding
Fractured reservoirs are generally simulated using Warren and Root26 dual-porosity (DP) approach. The main assumption of this approach is that the geometry of fractures are uniformly distributed and interconnected in reservoirs. This may be true for many cases of naturally fractured reservoirs. …

Stretched Exponential Decline Model as a Probabilistic and Deterministic Tool for Production Forecasting and Reserve Estimation in Oil and Gas Shales
… understand the interaction of the different fracture properties on reservoir response and production decline curve 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 …

Use of hydraulic tests to identify conceptual models of heterogeneity for fractured rock aquifers
… sites throughout the world are located in fractured rock formations. Responsible management of these resources and sites requires appropriate field characterization studies and modeling techniques to assess the impact of management alternatives. Characterization and modeling of aquifers is …

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 …
