Abstract

La présente invention se rapporte à un procédé destiné à séparer un élément tubulaire d'un puits de forage. Le procédé consiste à positionner un obturateur anti-éruption autour d'un élément tubulaire, l'obturateur anti-éruption comportant plusieurs pistons hydrauliques pouvant y être positionnés coulissants et plusieurs pales portées par les pistons hydrauliques pour entrer en prise avec l'élément tubulaire. Le procédé consiste en outre à percer l'élément tubulaire à l'aide d'un point de perçage d'au moins une des pales de sorte qu'une partie de l'élément tubulaire s'en déloge, et à balayer l'élément tubulaire à l'aide d'une surface de découpe d'au moins une des pales.
