Abstract Knowledge of the present-day crustal in-situ stress field is a key for the
understanding of geodynamic processes such as global plate tectonics and earthquakes. It …

Regional patterns of present-day tectonic stress can be used to evaluate the forces acting on
the lithosphere and to investigate intraplate seismicity. Most intraplate regions are …

To date, more than 7300 in situ stress orientations have been compiled as part of the World
Stress Map project. Of these, over 4400 are considered reliable tectonic stress indicators …

In this paper, we review a suite of techniques for determination of in situ stress orientation
and magnitude in deep wells and boreholes. As these techniques can be utilized in both …

The detailed cross‐sectional shape of stress induced well bore breakouts has been studied
using specially processed ultrasonic borehole televiewer data. We show breakout shapes …

AAPG grants permission for a single photocopy of an item from this publication for personal
use. Authorization for additional copies of items from this publication for personal or internal …

This book examines the experimental and theoretical aspects of bifurcation analysis as
applied to geomechanics. Coverage includes basic continuum mechanics for dry and fluid …

Inferring principal stress directions from geologic data, focal mechanisms, and in situ stress
measurements, we have prepared a map of principal horizontal stress orientations for the …

The conditions necessary for compressive and tensile failure of well bores drilled into
crystalline rock can be adequately represented by simple elastic failure criteria, and analysis …

The nature and origin of borehole elongation recorded by the four‐arm dipmeter calipers is
studied utilizing information obtained from hydraulic fracturing stress measurements and …
