Hi Everybody, It is about Breakout: compressive feature well known in petroleum geology (drilling) since Cox 1970 identified them and Bell & Gough 1979 published a sound interpretation, still used nowadays. Does anyone has published, identified or read about Breakout in HORIZONTAL WELL (or highly deviated)? Please, send me the references, certainly, I will appreciate.
