Borehole Breakouts in Transversely Isotropic Posidonia Shale
Borehole instabilities are frequently encountered when drilling through finely laminated, organic rich shales (Økland and Cook, 1998; Ottesen, 2010; etc.); such instabilities should be avoided to assure a successful exploitation and safe production of the contained unconventional hydrocarbons. …

Orientation of the maximum horizontal stress (SHmax) in the Orange basin and Outeniqua sub-basins of South Africa : neotectonic implications
… offshore provide an opportunity to utilise the borehole breakout technique to derive quality SHmax orientation data. In collaboration with the World Stress Map Project (WSM), and utilising borehole logs provided by the Petroleum Agency South Africa (PASA), training and software was provided to …

Cenozoic Tectonic Evolution of the Eastern Cordillera and Adjacent Basins
… and a variety of stress indicators (including borehole breakouts, natural fractures, and earthquake focal mechanism solutions) suggest that the Eastern Cordillera region in Colombia is an active zone of deformation that has undergone various stages of deformation. Knowledge of the tectonic …
