Numerical Methods for Flow in Fractured Porous Media [PDF]
arXiv, 2020 In this work we present the mathematical models for single-phase flow in fractured porous media. An overview of the most common approaches is considered, which includes continuous fracture models and discrete fracture models. For the latter, we discuss strategies that are developed in literature for its numerical solution mainly related to the ...

Fracturing behaviors of flawed granite induced by dynamic loadings: A study based on DIP and PFC
Deep Underground Science and Engineering, EarlyView.This research examines granite's mechanical properties under split‐Hopkinson pressure bar testing, focusing on factors such as grain size and flaw dimensions. The study reveals that tension cracks are prevalent across grain sizes, with most intergrain cracks occurring between feldspar and quartz.

Deep Underground Science and Engineering, EarlyView.This study reviews the research findings on the shear behavior of bolted rock joints in deep underground engineering, where they face high stress, high water pressure, and engineering disturbance. This study examines how the shear strength of bolted rock joints is affected by various factors, such as normal stress, rock compressive strength, joint ...

Deep Underground Science and Engineering, EarlyView.The mechanical characteristics of three different types of sandstones under high stress levels are studied. The degree of fragmentation of specimens increases with the applied stress level. The acoustic emission counting of different types of sandstones presents three stages: weakening, stabilizing, and surging.

Fracture system in shale gas reservoir: Prospect of characterization and modeling techniques
Journal of Natural Gas Geoscience, 2021 The quality and production of shale gas are directly dependent on the development of fractures. Especially in large-scale fracturing development, natural and hydraulic fractures play significant roles.
