Mapped form of folds

World Stress Map

In Situ Stress Measurement

• Seismic data– First motions– Stress drops

• Hydraulic Fracturing

• Overcoring

• Borehole Breakouts

Stress

• Lithostatic Stress– Stress due to rock weight– About 1 psi/ft

• Hydrostatic Stress– Fluid pressure due to depth in static system– About .433 psi /ft
