Constraining in-situ stresses at BETA by analysis of borehole images and downhole pressure data

This paper presents the analysis of in-situ stress magnitudes from observed borehole failures. Knowledge about the state of in-situ stress is important for many applications in the petroleum industry such as predicting sanding potential and reservoir behavior during depletion, and defining the range of safe mud weights to prevent lost circulation or wellbore collapse while drilling.
