Abstract

Methods and systems for quantifying and minimizing wellbore breakouts are disclosed. The methods include obtaining a mechanical earth model (MEM), determining a critical collapse pressure (CCP) using an inclination angle and the MEM, and determining an initial mud weight based on the CCP. The methods also include generating a breakout analysis using the initial mud weight, the MEM and a numerical modeling algorithm, updating the inclination angle of the planned wellbore, updating the CCP based on the updated inclination angle and the MEM, and updating the breakout analysis using the initial mud weight, the updated CCP, the MEM, and the numerical modeling algorithm. The methods further include selecting the updated CCP based, on the updated inclination angle that meets the stopping condition, calculating a final mud weight for the planned wellbore based on the updated CCP, and conditioning a drilling mud to the final mud weight, using a mud system.
