3D Geomechanical Modelling of CO2 Storage with Focus on Fault Stability

Jean-François Molinari, Brice Tanguy Alphonse Lecampion, Guillaume Anciaux, Nicolas Richart, Emil Gallyamov

A digital twin of the subsurface is crucial for all performance and risks assessments of a CO2 storage activities. The goal of the project is to develop an efficient fully-coupled geomechanical simulator for CO2 storage capable to model fluid flow along cr ...

Mode I fracture of thick adhesively bonded GFRP composite joints for wind turbine rotor blades

Véronique Michaud, Anastasios Vassilopoulos, Jialiang Fan

This article investigates the effects of voids, joint geometry, and test conditions on the quasi-static Mode I fracture performance of thick adhesive Double Cantilever Beam (DCB) joints such as those prevailing in wind industry and shipbuilding. The specim ...

Can a bi-lateral stress jump really arrest the height growth of a hydraulic fracture?

Brice Tanguy Alphonse Lecampion, Carlo Peruzzo, Barnaby Padraig Fryer

In certain industrial applications, vertical growth of hydraulic fractures beyond a targeted formation of interest can cause economic loss and pose a risk to environmentally sensitive layers [1]. In addition, when micro hydraulic fracturing is used to meas ...

Birth and ascent of buoyant hydraulic fractures

Brice Tanguy Alphonse Lecampion, Andreas Möri

Hydraulic fracturing treatments are often used in petroleum and other industries to increase the permeability of rock formations and occur naturally as magmatic intrusions. The resulting fractures, propagating perpendicularly to the minimum in-situ stress ...

INFLUENCE OF VOIDS ON THICK DCB JOINT BEHAVIOR

Véronique Michaud, Anastasios Vassilopoulos, Jialiang Fan

The influence of voids on the quasi-static Mode I fracture performance of thick adhesive joints was investigated in this article. Double Cantilever Beam (DCB) joints were manufactured with glass fiber reinforced epoxy adherends and SikaPower®-830 epoxy adh ...

Three-dimensional buoyant hydraulic fractures: finite volume release

Brice Tanguy Alphonse Lecampion, Andreas Möri

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 ...

Reactivating sealed joints: rock strength reduction and permeability enhancement … sometimes

Alexandra Roma Larisa Kushnir, Michael Heap

Rock masses are often criss-crossed by generations of discontinuities, including veins, fractures, and joints. The presence of fractures and joints can increase rock mass permeability and decrease rock mass strength. However, fluid flow within rock masses ...

Assessing real-world gait with digital technology? Validation, insights and recommendations from the Mobilise-D consortium

Kamiar Aminian, Anisoara Ionescu, Abolfazl Soltani, Francesca Salis

Background: Although digital mobility outcomes (DMOs) can be readily calculated from real-world data collected with wearable devices and ad-hoc algorithms, technical validation is still required. The aim of this paper is to comparatively assess and validat ...

Ascent and movement of buoyant fluids in the lithosphere

Brice Tanguy Alphonse Lecampion, Andreas Möri, Carlo Peruzzo

Hydraulic fractures are driven by an internal fluid pressure exceeding the minimum compressive stress, propagating in a direction perpendicular to the latter. This class of tensile fractures has gained interest over the last fifty years due to the developm ...
