E-454 - Tubing movement & forces

3 days PRO/TUBMFE
Level
Proficiency
Audience
  • Completion engineers or technicians.
Purpose
  • This course provides a thorough understanding of tubing movement and forces.
Learning Objectives
  • Upon completion of the course, participants will be able to:
  • analyze data and decide which element(s) or parameter(s) of a completion equipment must be modified to solve problems related to tubing movement,
  • write a completion program taking tubing behavior into account,
  • analyze correctly a tubing behavior-related problem encountered during operation and provide an adequate solution.
Prerequisite
  • No prerequisites for this course.
Ways and means
  • Exercises and a large case study.
  • Numerous animation and videos.

GENERAL PRINCIPLES 0.5 day
  • Presentation of the problem.
  • Parameters to be verified (worst place and case) and possible cures.
  • Reference state and present states of the well, various conventions.
  • Calculation principle.

CASE OF A DOWNHOLE BINDING DEVICE PERMITTING FREE TUBING MOVEMENT 1 day
  • Temperature effect.
  • Ballooning effect.
  • Piston effects (not including buckling).
  • Effect of the friction resulting from the fluid flow.
  • Buckling effect:
  • Awareness to the key parameters.
  • Buckling criteria.
  • Location of the neutral point and determination of the movement resulting from buckling.
  • Global effect: movement of the sliding binding device, tension force at the wellhead, …
