... criteria. It was discovered that breakout width stabilization is governed by equivalent plastic shear strain threshold whilst breakout depth stabilization is governed by equivalent plastic shear strain and volumetric strain thresholds. “First-of-its-kind” correlations for shales were subsequently developed...

.... Results also show that the initial breakout angle is the main factor that controls the breakout depth and the same initial breakout angle can be obtained from different stress- strength combinations so that there is a non-unique relationship between the in situ stresses and the breakout shape and size...
