As Elman mentions, our WellScan software allows to calculate the post-buckling shape of any string (drilling, completion, casing, liner...) and allows to quantify the consequences of buckling in the well.
The helical (and sinusoidal) buckling criteria usually used in the industry are too simple, and don't take into account the effects of Torque, Rotation and Doglegs. Our model allows a much deeper analysis.
We have published many papers showing the added value of this model (SPE-112571, SPE-119861, AADE 11-NTCE-9, SPE-151279 and many more)
It would be very interesting to play with the data on your specific well to see the differences with our model.
Can you please share more data about this case?
