Provided are methods for drilling a well having a wellbore that extends into the earth and that encounters a salt layer. Such methods include determinations of subsurface salt mobility and salt balance load mud weight and the performance of salt mobility tests to determine salt creep and wellbore enlargement problems. A salt formation may be determined from well log data and a drilling rate. The presence of salt creep may be determined from torque generated by the drilling assembly and a hook load. The initial mud weight of a drilling fluid may be adjusted to a salt balance load mud weight (SBLMW) to mitigate or prevent salt creep during drilling.
