A bonded-particle model for rock
D.O. Potyondy,Peter Cundall +1 more
TL;DR: In this paper, a numerical model for rock is proposed in which the rock is represented by a dense packing of non-uniform-sized circular or spherical particles that are bonded together at their contact points and whose mechanical behavior is simulated by the distinct element method using the two-and three-dimensional discontinuum programs PFC2D and PFC3D.

Mechanics of Hydraulic Fracturing
M. King Hubbert,David G. Willis +1 more
TL;DR: A theoretical examination of the fracturing of rocks by means of pressure applied in boreholes leads to the conclusion that, regardless of whether the fracturing fluid is of the penetrating or non-penetrating type, the fractures produced should be approximately perpendicular to the axis of least stress as mentioned in this paper.

Computer simulation of hydraulic fractures
TL;DR: In this article, the authors provide a brief historical background of the development of hydraulic fracturing models for use in the petroleum and other industries, and discuss scaling laws and propagation regimes that control the growth of hydraulic fractures from the laboratory to the field scale.

Influence of Geologic Discontinuities on Hydraulic Fracture Propagation (includes associated papers 17011 and 17074 )
Norman R. Warpinski,L.W. Teufel +1 more
TL;DR: In this article, mineback experiments and laboratory tests and analyses of these data are integrated to describe this complex fracture behavior, which can occur by arresting the growth of the fracture, increasing fluid leakoff, hindering proppant transport, and enhancing the creation of multiple fractures.
