High torque and drag is one of the main pdf what is acutal size in the directional wells. Friction models can be used for analysis during planning, drilling and after finishing the well.
To have an accurate model it is very important to have the correct friction factor. This paper studies one of these models called Aadnoy’s friction model. The purpose of this paper is to make an investigation on the limitations of the model, and also to find out how much the model can help for detecting the downhole problems. The author used an Aadnoy’s based excel sheet done by TL Longbow Prime company for studying the model. Also good torque results had been obtained for horizontal section despite the poor drag results. In the paper three different well profiles has been used during the study.
