Impact of the propagation algorithm on the convergence rate of hydraulic fracturing simulator to reference solutions

One key part of the numerical solution of ﬂuid-driven fracture propagation is the logic adopted to advance the fracture front during one time step. This is typically obtained by satisfying a quasi-static propagation condition. In this contribution, within ...

Simultaneous initiation and growth of multiple radial hydraulic fractures from a horizontal wellbore

Brice Tanguy Alphonse Lecampion

Multi-stage fracturing is the current preferred method of completion of horizontal wells in unconventional hydrocarbon reservoirs. Its core component consists in simultaneously initiating and propagating an array of hydraulic fractures. We develop a numeri ...

Hydraulic fracturing for unconventional resources development: challenges & opportunities for the mechanical community

Brice Tanguy Alphonse Lecampion

Oil and gas production from unconventional reservoirs (i.e. tight) now accounts for about half of the total US hydrocarbon production from essentially zero ten years ago. Such a drastic increase in production from unconventional resources was made possible ...

Robustness to formation geological heterogeneities of the limited entry technique for multi-stage fracturing of horizontal wells

Brice Tanguy Alphonse Lecampion

Robustness to formation geological heterogeneities of the limited entry technique for multi-stage fracturing of horizontal wells is investigated. It is necessary to simulate the complete process of initiation and propagation of multiple hydraulic fractures ...

Particle laden fluids in hydraulic fracturing

Brice Tanguy Alphonse Lecampion

The aim of hydraulic fracturing is to create a highly conductive pathway in the reservoir formation of interest. This is typically achieved by ``propping'' the created fracture with solid particles (i.e. proppant) in order to prevent complete closure of th ...

Development prospects of China's shale gas resources in light of global warming

Before 2013, it was widely believed that China's shale gas resources could radically alter the dynamics of supply for the world's biggest energy consumer, and there would be a shale gas boom in China, for two major reasons: China has a policy of encouragin ...

Analysis of TBM tunnelling performance in faulted and highly fractured rocks

Erika Paltrinieri

The thesis focuses on the study of the performance of TBMs in highly jointed and faulted rocks. Despite the great production rates recorded in favourable ground conditions, the TBM advance can be significantly slowed down in limiting geological situations ...

Frictional Properties of Opalinus Clay

Marie Estelle Solange Violay, Christophe Nussbaum, Luis Felipe Orellana Espinoza

Opalinus Clay formation (OPA) is an indurated shale under study in the context of geological deep disposal of nuclear waste in Switzerland. We will study the frictional properties of fault zones in OPA to evaluate the long-term safety performance of the re ...

Influence of weak layer heterogeneity and slab properties on slab tensile failure propensity and avalanche release area

Johan Alexandre Philippe Gaume

Dry-snow slab avalanches are generally caused by a sequence of fracture processes, including failure initiation in a weak snow layer underlying a cohesive slab followed by crack propagation within the weak layer (WL) and tensile fracture through the slab. ...

Exploratory experimental investigations on post-tensioned structural glass beams

Jean-Paul Lebet, Pieter Christian Louter, Jagoda Cupac

The mechanical response of post-tensioned glass beams is explored in this paper. This is done through bending experiments on post-tensioned glass beam specimens with either mechanically anchored or adhesively bonded steel tendons by which a beneficial pre- ...
