Numerical methods for hydraulic fracture propagation: a review of recent trends
TL;DR: A review of the basic approaches for hydraulic fracture simulation can be found in this article, where the authors discuss both continuum and meso-scales numerical methods as well as engineering models which typically make use of additional assumptions to reduce computational cost.
Journal ArticleDOI
The influence of plasticity in hydraulic fracturing
TL;DR: In this article, the influence of plasticity in hydraulic fracturing is examined and the results show that plastic yielding near the tip of a propagating fracture provides an effective shielding, resulting in an increase of the rock effective fracture toughness by more than an order of magnitude.
Journal ArticleDOI
The Effective Fracture Toughness in Hydraulic Fracturing
TL;DR: In this paper, the authors examined the effective fracture toughness approach which is used in hydraulic fracturing in order to explain the high net-pressures that are often observed in field operations.
Journal ArticleDOI
A review and perspective on far-field hydraulic fracture geometry studies
TL;DR: A review of the published literature and expert opinions shows that the traditional oil and gas industry paradigm for far-field hydraulic fracture geometry is changing to include the potential for creating complex fracture geometries as discussed by the authors.
Journal ArticleDOI
The influence of the cohesive process zone in hydraulic fracturing modelling
E. Sarris,Panos Papanastasiou +1 more
TL;DR: In this paper, the importance of the cohesive zone in the modelling of a fluid driven fracture under plain strain conditions was studied, where the fracture is driven by pumping of an incompressible viscous fluid at the fracture inlet.

A Path Independent Integral and the Approximate Analysis of Strain Concentration by Notches and Cracks
TL;DR: In this paper, an integral is exhibited which has the same value for all paths surrounding a class of notches in two-dimensional deformation fields of linear or non-linear elastic materials.

The mathematical theory of equilibrium cracks in brittle fracture
TL;DR: In this paper, the authors present a unified view of the way basic problems in the theory of equilibrium cracks are formulated and discuss the results obtained thereby, and the object of the theory is the study of the equilibrium of solids in the presence of cracks.
Journal ArticleDOI
Microcrack coalescence and macroscopic crack growth initiation in brittle solids
TL;DR: In this paper, the effect of microcracks on crack growth initiation in brittle solids was investigated with a view to determining the range of dominance of each mechanism, and the extent of shielding of the crack tip by the intervening micro-cracks was estimated under isotropic damage conditions.
Journal ArticleDOI
Experimental analysis of crack propagation in granite
TL;DR: In this paper, an experimental approach is used to demonstrate the concept of an effective crack length with double-edge-notched specimens of charcoal and rockville granite, and it is suggested that the process zone is larger for the larger grain-sized rock (rockville).
Journal ArticleDOI
Simulation of the fracture process in rock with application to hydrofracturing
TL;DR: In this paper, the authors presented a rational approach for the analysis of cracks in the transition range from initiation to the limit of linear elastic fracture mechanics (LEFM) applicability.
