English to Russian Tech/Engineering Geology Geomechanical modeling

The geomechanical model components for the study well location include:
• Pore pressure: The pore pressure was found to be well constrained on the suprasalt interval were drilling data was available and fairly to poorly constrained on the subsalt interval due to limited knowledge of mechanism of overpressure.
• Overburden gradient: fairly well constrained by synthetic density derived from sonic log calibrated to real density data points and limited real density log.
• Minimum Horizontal stress fairly constrained from Mathews and Kelly method with a matrix stress ratio of 0.8 calibrated to available leakoff tests.
• Maximum Horizontal stress fairly to poorly constrained assuming a transitional faulting regime, calibrated to computation of wellbore wall shear failure onset compared to wellbore enlargement.

In another context of the same document:
Because of that, the maximum horizontal stress may be estimated or constrained by means of back-analysis whenever caliper data and wellbore pressure during drilling is available.
