Initial Field Stress State

Many old fields have little or no measured stress data and the rest do not have anything approaching true 3D stress coverage. This means the effects of production on pressure depletion and stress adjustments at faults/sealing compartments cannot be calculated.


PSI can recover the original field stress state from interpreted reflection seismic using the full complement of products from 4DGeoStress software (above). Original fault seal/flow barrier detection may change within the evolving stress field and can be calculated/modeled. Later stage secondary recovery requires this full field stress evolution knowledge.


HPHT fields are especially in need of this life of field stress approach, during the pre-development casing planning stage.
