IN SITU STRESS
  
Our StressPATH analysis tool is a thermoporoelasticity-based simulator that helps predict and constrain in situ stress. The approach uses the geologic burial history to provide constraints on the likely stress state in a subsurface formation of interest. The technique includes relevant contractions and expansions of the rock due to overburden, pore fluid and thermal loads. It is used in conjunction with other data or approaches (e.g. leak-off tests, borehole breakouts, structural setting) for overall lower risk in the estimation of subsurface stress.
 Examples of use:
  1.     Estimating in situ stresses for pressure selection in core analysis
  2.     Predicting formation failure or yield during reservoir depletion
  3.     Predicting the presence of regional natural fractures at depth
  4.     Assessing risk of induced earthquakes from gas injection
  5.     Calibrating stress logs used in sand prediction
 
 
 
Thermal expansions and poroelastic contractions are accounted for in addition to the elastic distortions induced by vertical effective stress on the rock
