Hello,

Try with the following reference:

"Using borehole breakouts to constrain the complete stress tensor: Results from the Sijan Deep Drilling Project and offshore Santa Maria Basin, California"

Zajac, B.J. and Stock J.M., 1997, Journal of Geophysical Research, 102 (B5), 10083-10100

If you have more questions about breakout you can to consult with Cecilia Guzmán ([log in to unmask]). She is working with breakout data in hers PhD program.

Subject: About Breakout...

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.

With all my best wishes

A Saadallah
