SYSTEM AND METHOD FOR INTEGRATED WELLBORE STRESS, STABILITY AND STRENGTHENING ANALYSES

摘要

Systems and methods for an integrated wellbore stress, stability andstrengthening analysis are disclosed. An integratedgeomechanical tool can be used to analyze and evaluate stress along the lengthof the wellbore to identify a safe drilling mudweight window and help identify troublesome zones in the wellbore. Fracturelength may then be predicted in the identified troublesomezones by using a stress tensor calculated during the stress analysis. Thecalculated fracture length may be used to perform astrengthening analysis. After performing strengthening analysis, mud loss maybe predicted based on predicted fracture size calculatedduring the stress, stability and strengthening analyses.
