Title (EN) POLYMERIC MICROSPHERES AS DEGRADABLE FLUID LOSS ADDITIVES IN OILFIELD APPLICATIONS
(FR) MICROSPHÈRES POLYMÈRES COMME ADDITIFS DÉGRADABLES DE PERTE DE FLUIDE DANS DES APPLICATIONS DANS LE DOMAINE PÉTROLIER
Abstract:
(EN) Methods and apparatus for forming a fluid for use within in a subterranean formation including crosslinking a polymer along the surface of microspheres in a water-in-water emulsion and introducing the microspheres into the subterranean formation. Methods and apparatus for forming a fluid for use within in a subterranean formation including crosslinking a polymer along the surface of microspheres in a water in water emulsion, isolating the microspheres from the emulsion, and introducing the microspheres into the subterranean formation. Methods and apparatus for forming a fluid to treat a subterranean formation including introducing a crosslinkable polymer, partitioning agent, and crosslmker into a solvent, crosslinking the crosslinkable polymer, isolating beads of the crosslinkable polymer from the partitioning agent, introducing the beads into a fluid for treating a subterranean formation.
(FR) La présente invention concerne des procédés et un appareil destinés à former un fluide à utiliser à l'intérieur d'une formation souterraine, ledit procédé comprenant les étapes consistant à réticuler un polymère le long de la surface des microsphères dans une émulsion d'eau dans l'eau et à introduire les microsphères à l'intérieur de la formation souterraine. L'invention concerne également des procédés et un appareil destinés à former un fluide à utiliser à l'intérieur d'une formation souterraine, ledit procédé comprenant les étapes consistant à réticuler un polymère le long de la surface des microsphères dans une émulsion d'eau dans l'eau, à isoler les microsphères de l'émulsion, et à introduire les microsphères à l'intérieur de la formation souterraine. L'invention concerne de plus des procédés et un appareil destinés à former un fluide pour traiter une formation souterraine, ledit procédé comprenant les étapes consistant à introduire un polymère réticulable, un agent cloisonnant, et un agent réticulant à l'intérieur d'un solvant, à réticuler le polymère réticulable, à isoler les billes du polymère réticulable de l'agent cloisonnant, à introduire les billes à l'intérieur d'un fluide pour traiter une formation souterraine.
