This model has been used in calculation of specific key loads for casing design in well planning. A theoretical study of relevant literature regarding drilling loads has formed the basis for the development of a dedicated calculation model. The thesis has evaluated one of the leading well planning simulation tools in terms of functionality, reliability and potential weaknesses.

As the software developers allow limited insight into the applied algorithms and calculations it is difficult for the user to verify whether the results are in accordance with the required specifications for the well design. The tools have become increasingly advanced, allowing the user to perform multiple complex calculations within shorter time. Casing design planning has during the last decades developed from manual calculations performed by the engineer himself, to the use of advanced simulation tools.
