During the volume characterization, an azimuthal rotation of borehole breakouts was observed, indicating a stress perturbation caused by a major fault zone intersecting the experimental volume. In this study, we present the seismo-hydromechanical observations from...

These three failure mechanisms might work together or one of them could dominate the pipe sticking. A more comprehensive analysis of the three mechanisms was conducted for the second stuck-pipe incident...

..., but the influence of different rock failure criteria on the calculation results has always been neglected. Therefore, according to the linear poroelastic mechanics theory and different failure criteria of rock, the maximum horizontal stress in southwest Sichuan of China is calculated using the wellbore breakout...

... breakouts observed in borehole image logs. We utilize stress polygon (frictional faulting theory), wellbore failure analysis, drilling-induced fractures, and borehole breakouts to constrain the magnitude of the S Hmax in the well 78B-32 where both tensile and compressive failures occur. The constrained...

... ABSTRACT: Analysis of borehole breakouts is a widely used indirect method to estimate in situ stress and assess borehole instability. The Acoustic Televiewer (ATV) is commonly used to log borehole breakouts, but noise inherent to ATV data affects the interpretation of the breakouts. ATV data...
