Course content

The course covers a range of state-of-the-art models that describes various aspects in drillstring dynamics, such as surge and swab motions, torque and drag, bit rock interactions, axial, torsional and lateral vibration states. There is a focus on models that are particularly suited for real-time implementations, even though this is not an absolute requirement. The compulsory exercises involve substantial programming in Python, Matlab or equivalent.

The course will not be given unless 5 or more students are registered for the course.

Learning outcome

Competence

After completing the course, the student will be able to:

* Implement, discuss and evaluate mechanical models within drilling.

* Document strong communication skills of scientific results, including reports and oral presentations.

* Discuss how models can improve modern drilling operations, with focus on drillstring dynamics.

Knowledge and skills:

After completing the course, the student will be able to:

• Implement models in computers.
• Select a proper model based on the problem at hand.
• Justify the choice of method.
• Discuss own models in the light of other published models.
• Understand and discuss topics related to real-time implementation, including resolution choices, numerical stability and measured data as input.
