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.
