System and method for integrated wellbore stress, stability and strengthening analyses

A drilling system for drilling a wellbore in a formation with a drilling operation, the drilling system comprising:

• a memory;
• a display device;
• and
• a processor operatively coupled to the memory and the display device and adapted to execute program code stored in the memory to:
• receive a plurality of input parameters, each input parameter relating to at least one of the wellbore, the formation, and the drilling operation;
• generate a geomechanical model of the wellbore based on one or more of the received input parameters;
• perform a stress and stability analysis for the wellbore using the generated model based on one or more of the received input parameters to produce one or more stress and stability analysis output parameters;
• identify one or more troublesome zones of the wellbore based on the stress and stability analysis;
• perform a strengthening analysis for the wellbore using the generated model based on one or more of the received input parameters and one or more of the stress and stability analysis output parameters to produce one or more strengthening analysis output parameters;
• and
• perform a mud loss analysis for the wellbore based using the generated model on one or more of the received input parameters and one or more of the strengthening analysis output parameters to produce one or more mud loss analysis output parameters;
• and
• operate the drilling system using the one or more strengthening analysis output parameters and the one or more mud loss analysis output parameters to strengthen the one or more identified troublesome zones during drilling of the wellbore in the formation with the drilling operation.

A non-transitory program storage device, readable by a processor and comprising instructions stored thereon to cause one or more processors to:

• receive a plurality of input parameters, each input parameter relating to at least one of a wellbore, a formation in which the wellbore is drilled, and a drilling operation used to drill the wellbore with a drilling system;
• generate a geomechanical model of the wellbore based on one or more of the received input parameters;
• perform a stress and stability analysis for the wellbore using the generated model based on one or more of the received input parameters to produce one or more stress and stability analysis output parameters;
• identify one or more troublesome zones of the wellbore based on the stress and stability analysis;
• perform a strengthening analysis for the wellbore using the generated model based on one or more of the received input parameters and one or more of the stress and stability analysis output parameters to produce one or more strengthening analysis output parameters;
• and
• perform a mud loss analysis for the wellbore using the generated model based on one or more of the received input parameters and one or more of the strengthening analysis output parameters to produce one or more mud loss analysis output parameters;
• and
• operate the drilling system using the one or more strengthening analysis output parameters and the one or more mud loss analysis output parameters to strengthen the one or more identified troublesome zones during drilling of the wellbore in the formation with the drilling operation.
