Flow of non-Newtonian fluids in rock fractures is ubiquitous in engineering practice and
involves eg cement flow in tunnel grouting, drilling fluid flow when a fracture is met during …

Hydraulic fracturing is an essential technology for continuously developing non-renewable
energy, such as oil and gas. The erosion of solid-liquid two-phase flow in hydraulic …

Under the influence of the nonlinear fluid-solid coupling, hydraulic fracture exhibits various
propagation modes (such as toughness-or viscosity-dominated), which stem from the …

Hydraulic fracturing (HF) is one of the most effective stimulation techniques to enhance
reservoir permeability. The efficiency of an HF fluid injection depends on the pre-existing …

The high-speed flow of sand-carrying fracturing fluid through tee junctions causes severe
erosion and affects the safety of the fracturing operation. This study improves the traditional …

Highlights Anapparatus with precise controllability and large stiffness was designed to
investigate the mechanical behavior of rock grain interface. The fracture toughness and …

As a potential reservoir stimulation fracturing fluid, carbon dioxide (CO2) offers significant
advantages in enhancing the recovery of hydrocarbon resources and reducing reservoir …

One of the assumptions of Linear Elastic Fracture Mechanics is that the crack faces are
traction-free or, at most, loaded by bounded tractions. The standard Irwin's crack closure …

The hydraulic behavior of fractured rocks under shear‐thinning flow is a challenging topic of
interest in several fields, related either to environmental remediation or to natural resources …

Pores in coal are not only the main space for coalbed methane (CBM) occurrence but also
the space to be opened during CBM recovery. Therefore, the analysis of the impact of …
