Numerical investigation of the impacts of borehole breakouts on breakdown pressure
Zhang, Hua; Yin, Shunde; Aadnøy, Bernt Sigve (Peer reviewed; Journal article, 2019)Borehole breakouts appear in drilling and production operations when rock subjected to in situ stress experiences shear failure. However, if a borehole breakout occurs, the boundary of the borehole is no longer circular ...
