Although hydraulic fracturing is a mature technology that has been used commercially since
the late 1940s, the development of unconventional hydrocarbon fields with the combination …

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 …

The finite element method is a powerful and general numerical method used to simulate
subsurface processes. In this paper, we take recent hydraulic fracturing propagation …

We analyse a problem of a hydraulic fracture driven by a non-Newtonian shear-thinning
fluid. Fluid viscosity is described by the four-parameter truncated power-law model. By …

A new approach to seismic analysis has been introduced and demonstrated for a sequence
of recent seismic events recorded in the Blackpool region of Lancashire, UK. The seismic …

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 …

A new approach to defining the effective fracture toughness for heterogeneous materials is
proposed. This temporal averaging approach is process dependent, incorporating the crack …

A novel hydraulic fracture (HF) formulation is introduced which accounts for the hydraulically
induced shear stress at the crack faces. It utilizes a general form of the elasticity operator …

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 …

Many numerical modeling techniques have been employed to understand the phenomena
occurring during hydraulic fracturing. Despite the various complex models developed, such …
