Title
(EN) THERMITE REACTION CHARGE, METHOD FOR FORMING A THREEPHASED ROCK-TO-ROCK WELL BARRIER, AND A WELL BARRIER FORMED THEREOF
(FR) CHARGE DE RÉACTION DE THERMITE, PROCÉDÉ DE FORMATION D'UNE BARRIÈRE DE PUITS DE ROCHE À ROCHE À TROIS PHASES, ET BARRIÈRE DE PUITS FORMÉE À PARTIR DE CETTE DERNIÈRE
Abstract
(EN) This invention relates to a thermite reaction charge comprising bismuth oxide and aluminium adapted to react with a reaction rate giving a reaction time of 8 to 15 seconds for a thermite reaction charge of 30 to 100 kg from initialisation of the thermite reaction charge to at least 90 % of the thermite reaction charge is reacted, a method for forming a three-phased rock-to-rock barrier by applying the thermite reaction charge and a well barrier formed thereof.
(FR) La présente invention se rapporte à une charge de réaction de thermite comprenant de l'oxyde de bismuth et de l'aluminium apte à réagir avec une vitesse de réaction donnant un temps de réaction de 8 à 15 secondes pour une charge de réaction de thermite de 30 à 100 kg à partir de l'initialisation de la charge de réaction de thermite jusqu'à ce qu'au moins 90 % de la charge de réaction de thermite ait réagi, un procédé de formation d'une barrière de roche à roche à trois phases par application de la charge de réaction de thermite et une barrière de puits formée à partir de cette dernière.
