Active and Recently Completed Research Projects

The ongoing Research Projects were updated during the Spring 2024 Krakow Meeting and summaries were briefly presented at the Business Meeting.

U2021-2: “Predictive tool (and predictions) for critical velocity for Configurations (iii) and (iv) without centralizers, Phase V (McGill)”

  • Project Team: McGill University, Project Owner: Prof. Michael Paidoussis
  • Project Sponsors: Joe Ratigan and Sophie Minas
  • Experimental Stabilization of Brine Strings
  • Project Extension until July 2025

Learned through phases I and IV: Both flutter and buckling can occur in brine strings. Annular flow is of paramount importance in brine string deformation (in both configurations, iii and iv). Recommended new well completion techniques:

  1. Stiff centralizers to mitigate annular flow impacts,
  2. Increased tubing diameter in the cavern depth interval to increase deformation stiffness,
    1. Radial flow at the tubing exit to allow for increased brine injection velocities.
