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

Andreas Möri, Brice Tanguy Alphonse Lecampion, Seyyedmaalek Momeni

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

Andreas Möri, Brice Tanguy Alphonse Lecampion

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

Andreas Möri, Brice Tanguy Alphonse Lecampion, 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 ...

Hydraulic Fracture Closure Revealed Under Controlled Laboratory Condition

Brice Tanguy Alphonse Lecampion, Mohsen Talebkeikhah

This study observed hydraulic fracture propagation, arrest, and closure in permeable rocks. The experiment was conducted on a Molasse sandstone block in a true triaxial state of stress. The study monitored fracture opening at the wellbore and fluid pressur ...

Advanced Acoustic Emission-based SHM for Concrete Structures: Real-Time, High-Precision Imaging of Crack Geometry and Damage Source-type Using Moment Tensor Inversion

Brice Tanguy Alphonse Lecampion, Seyyedmaalek Momeni

In this paper, we introduce a novel automated and high-precision acoustic emission (AE) monitoring algorithm and the software SIMORGH, which is suitable for structural health monitoring (SHM) of civil structures. Initially developed for laboratory-scale hy ...

The energy balance of a hydraulic fracture at depth

Andreas Möri, Brice Tanguy Alphonse Lecampion

We detail the energy balance of a propagating hydraulic fracture. Using the linear hydraulic fracture model which combines lubrication flow and linear elastic fracture mechanics, we demonstrate how different propagation regimes are related to the dominance ...

Experimental Study of Underground Heat Storage via Hydraulic Fractures

Tristan Liardon, Brice Tanguy Alphonse Lecampion, Jean Vincent Daniel Naftalski, Mohsen Talebkeikhah

We present a laboratory setup to test the energy budget of underground heat storage in an otherwise impermeable rock through engineered fractures, a so-called Fracture Thermal Energy Storage (FTES) system. A hydraulic fracture is first created in a cubic s ...

Fluid-mediated impact of soft solids

Jean-François Molinari, Brice Tanguy Alphonse Lecampion, John Martin Kolinski, Antonio Joaquin Garcia Suarez

A viscous, lubrication-like response can be triggered in a thin film of fluid squeezed between a rigid flat surface and the tip of an incoming projectile. We develop a scaling for this viscous approach stage of fluid-mediated normal impact, applicable to s ...

Three-dimensional buoyant hydraulic fractures: finite volume release

Andreas Möri, Brice Tanguy Alphonse Lecampion

In impermeable media, a hydraulic fracture can continue to expand even without additional fluid injection if its volume exceeds the limiting volume of a hydrostatically loaded radial fracture. This limit depends on the mechanical properties of the surround ...
