Hi tom, 

find you a good explanation for soft string vs stiff string model 

Hope it helps 

Hello Windy,
Thanks for the guidance! Unfortunately i dont have access to Wellplan. By the way, when do we use soft string or stiff strong model? is there particular preference?
Regards, Tom

Hi Tom,

 

Yes for every single run BHA, Casing/Liner run, Completion run or any run you can check the T&D

If you can access wellplan landmark, it will provide you the workflow and input from wellpath, string configuration c/w MU tq, grade, material properties etc, Drilling parameter rotating on/off bottom RPM, WOB, friction factor casing - open hole, fluid properties in hole, model to be used stiff/ soft string.

 

The result will displayed the roadmap plot that can be used as guidance while drilling and string analysis if failure is occurred. It will be a tedious and long effort if not using a software as many things are considered and affected.

 

I have seen some paper talking about Artificial Intelligence approach as one method to predict T&D, Bit wear etc with bunch of data as input and let the machine do the equation.

Thanks for valuable material, appreciate it!
regards, Tom
