Hydro-mechanical coupled modeling of hydraulic fracturing using the mesh fragmentation technique
(2020-08-01)
The inclusion of special interface elements between standard finite elements is becoming a common technique to model discontinuities in porous media using the finite element method (FEM). Recently, it was proved that high ...
Coupled hydro-mechanical modelling of saturated fractured porous media with unified embedded finite element discretisations
(2022-04-01)
This paper presents the first unified finite element strategy for coupled hydro-mechanical (HM) analysis of fractured porous media where cracks arbitrarily intersect standard finite elements. This strategy is built by ...
On the use of high aspect ratio finite elements to model hydraulic fracturing in deformable porous media
(2019-06-15)
Hydraulic fracturing is a technique based on the injection of a viscous fluid at high pressure into an engineered well with the intention of initiating and propagating multiple fractures in a rock formation containing ...
Seismic responses to fluid pressure perturbations in a slipping fault
(American Geophysical Union, 2015)
Seismicity induced by fluid injection in a natural fault is investigated in situ in the near field of the source. We present synchronous seismic and hydromechanical measurements directly recorded in the decametric injection ...
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 ...

Hydromechanical simulation of Hydraulic Fracturing in naturally fractured reservoir using strong discontinuity approach
(2016-01-01)
Hydraulic Fracturing is a widely used method for enhancing oil exploitation in petroleum industry. In this method, some artificial fractures are induced in the reservoir by fluid injection and the overall rock permeability ...
Implementação do método totalmente acoplado para a resolução de sistemas hidromecânicos em um programa de elementos finitos em MatLab
(Universidade Estadual Paulista (Unesp), 2018-07-24)
Materiais porosos constituem uma grande gama de materiais que podem ser encontrados na natureza ou em forma artificial. Rochas reservatório é um exemplo importante desse tipo de material, sendo o estudo delas a motivação ...
Simulação de fraturamento hidráulico usando elementos finitos de elevada razão de aspecto com acoplamento hidromecânico
(Universidade Estadual Paulista (Unesp), 2016-05-09)
A técnica de fraturamento hidráulico é amplamente utilizada na indústria petrolífera para aumentar a permeabilidade da rocha-reservatório numa região próxima ao poço e permitir a extração, e consequente produção, de ...
