Theoretical Analysis of the Mechanism of Fracture Network Propagation with Stimulated Reservoir Volume (SRV) Fracturing in Tight Oil Reservoirs. [PDF]
PLoS ONE, 2015 Stimulated reservoir volume (SRV) fracturing in tight oil reservoirs often induces complex fracture-network growth, which has a fundamentally different formation mechanism from traditional planar bi-winged fracturing.

Modeling weak snow layer fracture in propagation saw test using an ice column model
Arctic, Antarctic, and Alpine Research, 2022 Fracture initiation and propagation in a weak snow layer are two primary processes of the slab avalanche formation process. This study proposes a model for the weak snow layer and investigates the fracture propagation process.

Gas-Driven Fracture Propagation [PDF]
Journal of Applied Mechanics, 1981 A one-dimensional gas-flow drives a wedge-shaped fracture into a linearly elastic, impermeable half space which is in uniform compression, σ∞, at infinity. Under a constant driving pressure, p0, the fracture/flow system accelerates through a sequence of three self-similar asymptotic regimes (laminar, turbulent, inviscid) in which the fracture grows ...

Hydraulic Fracture Propagation in Fractured Rock Mass
Applied Sciences, 2022 According to fracture mechanics theory, the initial cracking law and wing crack propagation model of compression shear rock cracks subjected to hydraulic pressure and far field stresses are discussed. The results of the theoretical study show that crack initiation strength is inversely related to hydraulic pressure, that hydraulic pressure aggravates ...

, 2023 AbstractIn previous theories regarding hydraulic fracture propagation, it is usually assumed the fluid pressure within the hydraulic fracture is constant in the calculation of the surrounding stress field. The actual fluid pressure during fracturing process, however, is often fluctuating, due to the disturbance of the irregular surface of rock fracture
