Importance of Field Measurements for Soil Modeling and Wellhead Fatigue
Wellhead and conductor fatigue is an important aspect of well integrity assurance. In practice, the conductor-soil interaction under cyclic loading is modelled using the soil resistance-displacement springs. Use of an appropriate soil model is essential for accurate determination of stress cycles and fatigue damage in the wellhead and conductor.

Insights
In this webinar, the performance of a design soil model will be evaluated using riser and BOP motion measurements collected during a recent drilling campaign. The impact of inaccurate soil models on the conductor fatigue results will also be discussed.
Learning Outcomes:
Understand the challenges of soil-conductor interaction
Learn the importance of using field data to verify and calibrate soil models
Become familiar with the risks associated with inaccurate soil models
Find out how to calculate wellhead fatigue using field data
This webinar is ideally suited to drilling riser engineers, subsea well engineers and geotechnical engineers.
This is a recording of a live webinar which took place in December 2017.
