Buoyancy-driven crack propagation: the limit of large fracture toughness [PDF]
We study steady vertical propagation of a crack filled with buoyant viscous fluid through an elastic solid with large effective fracture toughness. For a crack fed by a constant flux Q, a non-dimensional fracture toughness K=Kc/(3μQm3/2)1/4 describes the

Moiré interferometry applied to fracture in titanium tubes [PDF]
Despite there being a substantial body of evidence to the contrary, moiré interferometry is often regarded - even by some adherents - as a curiosity of the optics lab.

Analysis of the Influence of Hydraulic Fracturing Fluid Velocity on Fracture Propagation
To reveal the influence of fracturing fluid velocity on hydraulic fracturing fracture propagation, a hydraulic fracturing numerical model was established based on a coalbed methane (CBM) field in the northeast of China.

Hydraulic fracture modeling in naturally fractured reservoirs [PDF]
Hydraulic fracturing of horizontal wells is one of the key technological breakthroughs that has led to the shale revolution. Hydraulic fracturing models are used to engineer hydraulic fracture design and optimize production.

A Random‐XFEM technique modeling of hydraulic fracture interaction with natural void
In this paper, a Random‐XFEM technology was employed to simulate hydraulic fracture interaction with the natural void in a random field of Young's modulus.

Complex Fluids and Hydraulic Fracturing [PDF]
Nearly 70 years old, hydraulic fracturing is a core technique for stimulating hydrocarbon production in a majority of oil and gas reservoirs. Complex fluids are implemented in nearly every step of the fracturing process, most significantly to generate and sustain fractures and transport and distribute proppant particles during and following fluid ...

Hydraulic Fracturing‐Induced Seismicity [PDF]
AbstractHydraulic fracturing (HF) is a technique that is used for extracting petroleum resources from impermeable host rocks. In this process, fluid injected under high pressure causes fractures to propagate. This technique has been transformative for the hydrocarbon industry, unlocking otherwise stranded resources; however, environmental concerns make

Beam model for hydraulic fracturing [PDF]
We investigate numerically the shape of cracks obtained in hydraulic fracturing at constant pressure using a square-lattice beam model with disorder. We consider the case in which only beams under tension can break, and discuss the conditions under which the resulting cracks may develop fractal patterns.
