Fractured reservoirs account for a majority of the oil production worldwide and often have low recovery rate. Fracture characterization is important in building reservoir flow models for enhanced oil recovery. Information about fracture orientation, fracture spacing, and fracture compliances is essential. When a fracture network consisting of multiple sets of fractures with variable fracture sp...

Passive seismic characterization is an environmentally friendly method to estimate the properties of subsurface. Among its applications, we find monitoring geothermal reservoirs. One key characteristic ensure a productive management these reservoirs degree fracture connectivity and evolution, as it affects flow fluids within formation. In this work, explore effects on Rayleigh wave velocity dis...

Fracture effectiveness evaluation has an important impact on the efficient exploration and development of ultra-deep fractured reservoirs. Based liquid production profile results collected during Keshen gas field based traditional static fracture density, opening filling degree, reservoirs is carried out from perspectives activity, connectivity. The show that characteristics, such as density pr...

Osteoporosis is a metabolic disease characterized by low bone mass and microarchitectural deterioration of bone tissue, leading to enhanced bone fragility and a consequent increase in fracture risk. Bone fragility depends on bone density, turnover and microarchitectural features, such as relative trabecular volume, spacing, number and connectivity. Previous fragility fractures increase the frac...

Using the lattice Boltzmann method, we study fluid flow in a two-dimensional (2D) model of fracture network of rock. Each fracture in a square network is represented by a 2D channel with rough, self-affine internal surfaces. Various parameters of the model, such as the connectivity and the apertures of the fractures, the roughness profile of their surface, as well as the Reynolds number for flo...

Back Cover: Article 2200864 by Esther Amstad and co-worker demonstrates that the stiffness of swollen microgel-reinforced hydrogels (MRHs) depends on connectivity between fragmented microgels, which is closely related to their initial volume fraction. By contrast, fracture toughness linearly scales with effective fraction microgels in MRHs regardless connectivity. These insights provide univers...

[1] While permeability scaling of fractured media has been so far studied independently at the fractureand networkscales, we propose a numerical analysis of the combined effect of fracture-scale heterogeneities and the network-scale topology. The analysis is based on 2 10 discrete fracture network (DFNs) simulations performed with highly robust numerical methods. Fracture local apertures are di...

Hydraulic fracturing is usually employed to create a complex fracture network enhance heat extraction in the development of an enhanced geothermal system. The depends on conduction from rock matrix flowing fractures and convection through network. Therefore, geometries have important influences thermal breakthrough.
