Title (EN) WATER ABSORBING POLYMERS FOR TREATMENT OF BRINES AND WATER-BASED DRILLING FLUIDS
(FR) POLYMÈRES D'ABSORPTION D'EAU POUR LE TRAITEMENT DE SAUMURES ET DE FLUIDES DE FORAGE AQUEUX
Abstract: front page image
(EN)A method for removing water from a wellbore fluid is disclosed. The method may include the steps of contacting a wellbore fluid with a water absorbing polymer, where the wellbore fluid includes an aqueous fluid, allowing the water absorbing polymer to interact with the wellbore fluid for a sufficient period of time so that the water absorbing polymer absorbs at least a portion of water in the aqueous fluid, and separating the water absorbing polymer containing the absorbed water from the wellbore fluid.
(FR)La présente invention concerne un procédé pour l'élimination de l'eau d'un fluide de trou de forage. Le procédé peut comprendre les étapes suivantes: la mise en contact d'un fluide de trou de forage avec un polymère d'absorption d'eau, ledit fluide de trou de forage comportant un fluide aqueux, permettant l'interaction du polymère d'absorption d'eau avec le fluide de trou de forage pour une période de temps suffisant de sorte que le polymère absorbe au moins une partie de l'eau dans le fluide aqueux, et la séparation du polymère d'absorption d'eau contenant l'eau absorbée du fluide de trou de forage.
