A geostatistical approach to estimating the parameters of a 3D Cox-Boolean discrete fracture network from 1D and 2D sampling observations
(Elsevier Ltd, 2019)
© 2018 Elsevier Ltd This work addresses the problem of parameter inference in the Cox-Boolean discrete fracture network model, in which the fractures are represented by flat discs with random orientations and diameters ...
Robust estimation of the fracture diameter distribution from the true trace length distribution in the Poisson-disc discrete fracture network model
(Elsevier SCI Ltd, 2018)
A distribution-free approach is proposed to estimate the fracture size distribution from a given trace length distribution, assuming that the fracture network can be represented by a Poisson-disc model. This approach ...
Mixed Virtual Elements for discrete fracture network simulations
(Elsevier Science, 2017-10)
The present work deals with the simulation of the flow in Discrete Fracture Networks (DFN), using the mixed formulation of the Virtual Element Method (VEM) on polygonal conforming meshes. The flexibility of the VEM in ...
Structural characterization of naturally fractured geothermal reservoirs in the centralupper rhine graben
(Elsevier, 2021)
Image logs and the continuous coring of 8 geothermal wells in the Central Upper Rhine Graben (URG) are used for the structural characterization of 3 geothermal reservoirs at Soultz-sous-Forets, Rittershoffen and Illkirch ...
Reactivation of natural fractures network by hydraulic fracturing
(2020-11-18)
Modelling the process of induced fracture initiation, propagation and interaction with natural fractures is a very challenged task. Significant progress has been made in recent years in the development of complex fracture ...
Seismic Attenuation and Stiffness Modulus Dispersion in Porous Rocks Containing Stochastic Fracture Networks
(Wiley, 2018-01)
Understanding seismic attenuation and modulus dispersion mechanisms in fractured rocks can result in significant advances for the indirect characterization of such environments. In this paper, we study attenuation and ...
A new discrete fracture approach based on the use of coupling finite elements for modeling fluid transport in naturally fractured porous media
(2021-12-01)
The presence of natural fractures in a porous medium strongly influences the fluid flow path. The complex geometric characteristics of the fracture network create preferential channels that change the permeability of the ...
Modeling the closure behavior of natural fractures in porous media using high aspect ratio interface elements
(2021-01-01)
Many reservoirs consist of fully saturated rock masses containing a very complex natural fracture network. In such cases a decrease in the fracture fluid pressure reduces its aperture due to an increase in the effective ...
