Solid particulate additives are sometimes used to promote the uniform growth of multiple hydraulic fractures in horizontal oil and gas wells. The principle is that solid particulates block, accumulate, and form larger porous plugging zones preferentially a ...

To break or not to break: The role of secondary mineralisation on joint reactivation in sandstone

Alexandra Roma Larisa Kushnir, Michael Heap

Discontinuities, including fractures and joint sets, modify the fluid transport properties and strength of rock masses. While open fractures and joints increase rock mass permeability and decrease rock mass strength, fluid flow within these structures can ...

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 ...

Buoyant hydraulic fractures (HF) are a viable approach to model propagating magmatic intrusions in the lithosphere. Solutions for fully planar three-dimensional (3D) HF suggest the existence of a family of solutions as a function of fluid and solid propert ...

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 ...

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 ...

Buoyant Hydraulic Fractures: How they Emerge, Grow, and get Arrested

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

Most anthropogenic applications of hydraulic fracturing treatments are performed in sedimentary basins. In these geological formations, the minimum compressive stress is usually horizontal and increases with depth. As a result, hydraulic fractures grow alo ...

Linear elastic fracture mechanics has been widely used to describe the propagation of hydraulic fractures in rocks [1]. The embedding material is generally considered to be elastic and permeable, but the fluid exchange between the fracture and the media is ...

Seismic swarms are often interpreted to be driven by natural fluid pressurization in the Earth’s crust, when seismicity is observed to spread away from a common origin and follows approximately a square-root-of-time pattern of growth. On the other hand, a ...

Experimental Investigation of Hydraulic Fracture Closure in a Porous Sandstone

Brice Tanguy Alphonse Lecampion, Seyyedmaalek Momeni, Mohsen Talebkeikhah, Guanyi Lu

Depending on the type of fracture propagation regime when the injection stops, the closure of the fracture may occur exactly after the injection ceases, in the case where the fracturing process is dominated by fracture energy, or the fracture propagate for ...
