Fundamentals of Thermal Well Design

27 November 2017

Instructors: Trent Kaiser, Mark Chartier

Read the Letter of Support from the instructor.


Tubular structures in thermal applications are subject to unique design challenges that cannot be addressed with conventional methods. In conventional design, the structure “fails” when thermally induced loads yield the pipe, but thermal wells often must operate under such conditions and industry experience demonstrates that wells can do so reliably. Designing a structure that remains stable requires knowledge of strain-based design: the distinction between strength and stiffness, the effects of variability in strength and stiffness, load path dependencies, post-yield material behavior, and strain localization. Collateral considerations for resistance to environmental effects, geomechanical loads, and production management can also challenge intuition developed in conventional well design. In this course, participants will learn to “think strain, not stress” for well structure design and gain exposure to other aspects of thermal well design.

This course provides an introduction to subsurface well design for thermally stimulated wells, including discussion of why design approaches for thermal wells must differ from conventional approaches.  The concept of strain-based design will be examined with focus on the fundamental inputs required for a successful design. Specific topics include:

  • Mechanical properties for thermal OCTG
  • Casing and Liner design considerations
  • Connections for thermal stimulation
  • Considerations for environmental exposure
  • Production management topics pertinent to liner design

All topics will include discussion of real-world examples to augment discussion. Participants will leave with an increased understanding of design fundamentals for thermal wells and be able to evaluate the suitability of and required inputs for a design basis for casing in thermal applications.
