The Utah FORGE 2022 hydraulic stimulations: tensile hydraulic fractures or/and fluid-induced dilatant shear ruptures?

We investigate two hydraulic stimulation stages performed in April 2022 at the Utah FORGE enhanced geothermal system test site using analytical solutions and numerical modeling of fluid-induced tensile and shear rupture problems. These stimulation stages d ...

Hydraulic Fracture Propagation Across Pre-existing Discontinuities in an Anisotropic Rock: Experimental Evidence and Insights from Scaling Relations

Brice Tanguy Alphonse Lecampion, Seyyedmaalek Momeni, Andreas Möri

Laboratory experiments have been conducted on anisotropic slate specimens to study the behavior of hydraulic fractures (HFs) when encountering discontinuities. The experiments target specific propagation regimes, including toughness-dominated, lag-viscosit ...

Morphology of buoyancy-driven multiple hydraulic fractures

Brice Tanguy Alphonse Lecampion, Andreas Möri

We investigate the problem of simultaneous propagation of multiple hydraulic fractures in situations when the effect of buoyancy is important. While such fractures often occur in nature as magmatic dikes, they also bear technological relevance. For instanc ...

Conditions for the local arrest of a hydraulic fracture by a region of larger toughness

Brice Tanguy Alphonse Lecampion

We investigate the conditions for the local arrest of a hydraulic fracture encountering a region of larger toughness. The propagation of a hydraulic fracture strongly depends on the ratio between the energy dissipated in the creation of new fracture surfac ...

Adaptive Interface-Pinns (Adai-Pinns) for Transient Diffusion: Applications to Forward and Inverse Problems in Heterogeneous Media

Brice Tanguy Alphonse Lecampion

We model transient diffusion in heterogeneous materials using a novel physics-informed neural networks framework (PINNs) termed Adaptive interface physics-informed neural networks or AdaI-PINNs (Roy et al. arXiv preprint arXiv:2406.04626, 2024). AdaI-PINNs ...

Maximum size and magnitude of injection-induced slow slip events

Brice Tanguy Alphonse Lecampion, Alexis Alejandro Sáez Uribe

Fluid injections can induce aseismic slip, resulting in stress changes that may propagate faster than pore pressure diffusion, potentially triggering seismicity at substantial distances from injection wells. Constraining the maximum extent of these aseismi ...

FASTDASH: An Implementation of 3D Earthquake Cycle Simulation on Complex Fault Systems Using the Boundary Element Method Accelerated by H-matrices

Brice Tanguy Alphonse Lecampion, Carlo Peruzzo

Summary Fault systems have geometrically complex structures in nature, such as stepovers, bends, branches, and roughness. Many geological and geophysical studies have shown that the geometrical complexity of fault systems in nature decisively influences th ...

How Stress Barriers and Fracture Toughness Heterogeneities Arrest Buoyant Hydraulic Fractures

Brice Tanguy Alphonse Lecampion, Andreas Möri, Carlo Peruzzo

In our study, we investigated the impact of changes in Mode I fracture toughness and stress barriers on fully developed planar, buoyant hydraulic fractures assuming linear elastic hydraulic fracture mechanics. We present scaling-based arguments to predict ...

How contained hydraulic fractures emerge from layers of alternating fracture toughness

Brice Tanguy Alphonse Lecampion, Carlo Peruzzo

Hydraulic fractures are used to enhance the hydrocarbon production from low permeability rocks and to measure the minimum in-situ principal stress in rock formations. In these cases, the fracture growth above (or below) the formation of interest is a key m ...

Design of a Meso-Scale Test of a Fracture Thermal Energy Storage (FTES) System

Brice Tanguy Alphonse Lecampion

Seasonal storage of thermal energy has the potential to both significantly reduce the total energy requirements for heating and cooling of buildings, and also allow for the flexibility to store thermal energy from intermittent sources. With approximately h ...
