Abstract
A method for predicting buckling behavior in a torque and drag analysis of a tubular string in a wellbore includes performing a first finite element analysis (FEA) on the tubular string. The method also includes determining one or more first properties of the tubular string based upon the first FEA. The method also includes identifying a possible buckling zone in the tubular string based upon the one or more first properties. The method also includes splitting the possible buckling zone into a plurality of segments. The method also includes performing a second FEA on one or more of the segments. The method also includes determining one or more second properties of the tubular string based upon the second FEA. The method also includes comparing the one or more first properties of first FEA to the one or more second properties of second FEA to identify incremental changes therebetween.
