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 ...

Arrest Mechanisms of Buoyant Hydraulic Fractures

Andreas Möri, Brice Tanguy Alphonse Lecampion, Dmitriy Garagash, Carlo Peruzzo

Hydraulic fracturing (HF) treatments can form widespread fractures. Understanding their containment at depth is critical, given the positive buoyancy contrast between the fracturing fluid and the surrounding rock, promoting upward growth. We study arrest m ...

Three-dimensional hydraulic fracture propagation in homogeneous and heterogeneous media

Carlo Peruzzo

Hydraulic fractures are tensile fractures that occur in solid materials due to the natural intrusion or anthropogenic injection of a viscous fluid into a fracture channel. The deliberate creation of hydraulic fractures is part of an industrial technology h ...

Elongated hydraulic fracture emerging from layers of alternating fracture toughness

Brice Tanguy Alphonse Lecampion, Carlo Peruzzo

Whether used to enhance the hydrocarbon production from low permeability rocks or to measure the minimum in-situ principal stress in rock formations, height growth of a hydraulic fracture above the formation of interest is a key metric for the design of su ...

On stepwise advancement of fractures and pressure oscillations in saturated porous media

Carlo Peruzzo

PERGAMON-ELSEVIER SCIENCE LTD2019

Dynamics of fracturing saturated porous media and self-organization of rupture

Enrico Milanese, Carlo Peruzzo

Analytical solutions and a vast majority of numerical ones for fracture propagation in saturated porous media yield smooth behavior while experiments, field observations and a few numerical solutions reveal stepwise crack advancement and pressure oscillati ...

Performance criteria for healthy and energy efficient buildings: definition, assessment and building classification

Claude-Alain Roulet, Carlo Peruzzo

One of the aims of the HOPE project is to develop a method to assess healthiness and energy efficiency of buildings and strategies to optimise their performance towards health and energy efficiency. In this project, a building is defined "Healthy and Energ ...

Assessment of health risks in buildings using health hazard algorithms

Claude-Alain Roulet, Lee Ann Nicol, Carlo Peruzzo

The EU project HOPE (Health Optimisation Protocol for Energy-efficient buildings) seeks to characterise those buildings that achieve good performance in both energy efficiency and occupant health and comfort. This project involved two stages of fieldwork: ...
