ABSTRACT: This paper presents the details and results of packer permeability testing performed in five deep inclined onshore constructing a subsea tunnel for the transmission of power cables across the Strait of Belle Isle. Over 200 packer permeability tests were carried out using several different equipment arrangements to assess the in-situ permeability of the geological formations. As part of the permeability testing, moderately high test pressures were used during packer testing in an attempt to initiate hydrojacking. This paper provides an overview of the test methodology, packer test equipment and results of packer testing. Interpretation of the data is discussed with consideration of the test methods and equipment used.
RÉSUMÉ: forage obliques profonds sure le rivage. Les observations sur le terrain ont été exécutées dans le cadre du projet de la p--dessus de 200 essais de perméabilité ont été réalisés avec un packer utilisant plusieurs aménagements de matériels différents pour évaluer la perméabilité de formations géologiques in situ. Dans le cadre des essais de perméabilité, des essais à haute pression ont été utilisés
