Abstract Geothermal energy, featured as a renewable low‐carbon energy resource, exhibits great potential in mitigating global warming. However, efficient mining of geothermal from hot dry rock remains challenging due to the lack thermoporoelastic modeling approach that allows for integrated simulation hydrofracturing and fluid circulation, poor understanding mechanisms hydraulic stimulations. To conquer these challenges, we propose an advanced approach, which enables us deal with interplay...
Summary Massive hydraulic fracturing requires an enormous consumption of water and introduces many potential environmental issues. In addition, water-based fluid tends to be trapped in formations, reducing oil/gas-phase relative permeability, causes clay-mineral swelling, which lowers absolute permeability. Carbon dioxide (CO2) is seen as a promising alternative working that poses no formation-damage risk, it can stimulate more-complex extensive fracture networks. However, very little, if...
Summary A fully coupled thermal/hydromechanical (THM) model for hydraulic-fracturing treatments is developed in this study. In model, the mixed finite-volume/finite-element method used to solve system, which multipoint flux approximation L-method calculate interelement fluid and heat flux. The Gu et al. (2011) crossing criterion extended a 3D scenario delineate behaviors as hydraulic fractures meet inclined natural fractures. Moreover, modified Barton (1985) proposed by Asadollahi (2010)...
Summary Carbon capture and storage is crucial in combating global climate change by effectively mitigating carbon emissions. Deep saline aquifers possess the largest identified capacity, making them preferred location. However, when CO2 injected underground, it tends to escape through interconnected fractures or reactivated faults toward ground due buoyancy. Thus, studying impact of injection on feedback effect fault activation leakage significant. In this work, we develop validate a fully...
Summary Geothermal energy is regarded as a promising and attractive alternative to traditional sources, with the concept of enhanced geothermal systems (EGS) enabling viable commercial development. EGS modeling requires integration multiscale, multiphysics processes, necessitating comprehensive numerical model effectively evaluate heat extraction performance. The advantages explicitly representing fracture networks directly simulating thermal-hydrologic-mechanical (THM) coupling coupled...
Accurate and efficient simulation of fluid heat flow in fractures has long been a topic interest for fractured reservoirs, e.g., enhanced geothermal systems (EGS) unconventional oil/gas formations. In this paper, we propose flexible effective modeling approach, the extended embedded discrete fracture model (XEDFM), to simulate reservoirs with 3-D non-planar networks. Compared conventional (EDFM), XEDFM possesses two major merits: (1) separation discretization matrix gridding provides maximum...

Abstract Accurate numerical modeling of fracture propagation and deflection in porous media is important the development georesources. To this end, we propose a novel framework to simulate nonplanar three‐dimensional growth within poroelastic media, using an iteratively coupled approach based on time‐/scale‐dependent stiffness. In approach, propagating fractures are explicitly tracked fitted at each step triangular elements that independent matrix discretized by hexahedral grids. The finite...
The stability and mobility of proppant packs in hydraulic fractures during hydrocarbon production are numerically investigated by the lattice Boltzmann-discrete element coupling method (LB-DEM). This study starts with a preliminary settling test, from which solid volume fraction 0.575 is calibrated for pack fracture. In established workflow to investigate flowback, displacement applied fracture surfaces compact generated as well further mimicking embedment under closure stress. When pressure...
Abstract Multi-well completion techniques, such as sequential fracturing, zipper fracturing and simultaneous have been proposed to improve fracture complexity connectivity. Critical geomechanics behind the multi-well-frac techniques include pore pressure propagation, cooling stress, tip-induced shear reversal of stress anisotropy. To optimize treatments, we numerically investigated growth from perspective thermo-hydro-mechanical coupling. The coupled fluid-heat flow model is based on a mixed...

Under fully implicit solution framework, the finite volume approach employed solve reactive‐convective‐dispersive system. Based on embedded discrete fracture model, novel modeling proposed describe with various apertures in three dimensions (3‐D). verified against preexisting numerical models. Then, 3‐D field case...
Abstract Despite the variety of studies that have investigated development fracture networks during kerogen maturation in organic‐rich shale, interaction modes and generation mechanisms three‐dimensions are not yet fully understood. In this study, we introduce a novel numerical approach to model evolution swarms with three‐dimensional nonplanar geometries. This enables precise simulation propagation, interplay, coalescence variable apertures geometries via solving fluid flow, growth, stress...
