Title (EN) WELL COMPLETION FOAMED SPACER FLUIDS AND METHODS
(FR) FLUIDES DE SEPARATION EN MOUSSE POUR COMPLETION DE PUITS ET PROCEDES ASSOCIES
Abstract:
(EN) Well completion foamed spacer fluids and methods of using the foamed spacer fluids are provided. A method of the invention for displacing a first fluid from a well bore with an incompatible second fluid comprises the following steps. A foamed spacer fluid is placed between the first and second fluids to separate the first and second fluids and to remove the first fluid from the walls of the well bore. Thereafter, the first fluid and the foamed spacer fluid are displaced from the well bore with the second fluid.
(FR) Cette invention concerne des fluides de séparation en mousse pour complétion de puits ainsi que des procédés d'utilisation de ces fluides de séparation en mousse. Un procédé de cette invention permettant d'évacuer un premier fluide d'un puits de forage à l'aide d'un second fluide incompatible comprend les étapes suivantes consistant : à placer un fluide de séparation en mousse entre le premier et le second fluide afin que ces deux fluides soient séparés et que le premier fluide soit éliminé des parois du puits de forage ; puis à évacuer le premier fluide et le fluide de séparation en mousse du puits de forage à l'aide du second fluide.
