Arrest of a radial hydraulic fracture upon shut-in of the injection
Brice Tanguy Alphonse Lecampion, Andreas Möri
We investigate the propagation and arrest of a radial hydraulic fracture upon the end of the injection. Depending on the regime of propagation at the time of shut-in of the injection, excess elastic energy may be stored in the surrounding medium. Once the ...
2021Role of stress field orientation on fault reactivation
Hydraulic fracturing involves injecting water under high pressure into the bedrock formation to enhance permeability of deep geo-reservoirs. Faults are planar discontinuities cutting the reservoirs, and their reactivation during injection depends of their ...
2020In vitro Implementation of Photopolymerizable Hydrogels as a Potential Treatment of Intracranial Aneurysms
Dominique Pioletti, Christophe Moser, Andreas Schmocker, Oriane Poupart
Intracranial aneurysms are increasingly being treated with endovascular therapy, namely coil embolization. Despite being minimally invasive, partial occlusion and recurrence are more frequent compared to open surgical clipping. Therefore, an alternative tr ...
FRONTIERS MEDIA SA2020Slickwater hydraulic fracture propagation: near-tip and radial geometry solutions
Brice Tanguy Alphonse Lecampion, Haseeb Zia
We quantify the importance of turbulent flow on the propagation of hydraulic fractures (HF) accounting for the addition of friction reducing agents to the fracturing fluid (slickwater fluid). The addition in small quantities of a high molecular weight poly ...
2019Structure and Activity of the Type VI Secretion System
The type VI secretion system (T6SS) is a multiprotein machine that uses a spring-like mechanism to inject effectors into target cells. The injection apparatus is composed of a baseplate on which is built a contractile tail tube/sheath complex. The inner tu ...
