CA 2226796

A dissolvable release mechanism to allow a travel joint to be run down-hole in a locked position to accommodate full compressive and tension loading integrity. The joint is released through exposure to caustic well fluids to accommodate fluctuations in compressive and tensive forces in a well formation.

Mécanisme soluble de dégagement d'un joint mobile pour permettre de descendre ce dernier vers le fond en position verrouillée en vue d'assurer une totale intégrité en charge de tension et de compression. Le joint est libéré sous l'effet d'une exposition à des fluides à la soude caustique en puits pour permettre une fluctuation des forces de tension et de compression dans une formation de puits.
