The present invention relates to fluid systems comprising a first fluid comprising carbon dioxide and a second fluid comprising an alkaline crosslinked fluid. The fluid combinations of the present invention may be used, for example, in hydraulic fracturing, frac-packing, and gravel packing. Some embodiments of the present invention provide systems for treating a subterranean formation comprising a first fluid comprising a foamed carbon dioxide fluid, an emulsion of carbon dioxide, or a carbon dioxide gel; and, a second fluid comprising an alkaline crosslinked fluid.
L'invention concerne des systèmes fluidiques présentant un premier fluide comportant du dioxyde de carbone et un second fluide comportant un fluide alcalin réticulé. Les composés fluides peuvent être utilisés par exemple, pour la fracturation hydraulique, la compaction à fracturation et le gravillonnage. L'invention concerne en outre des systèmes pour le traitement d'une formation souterraine, présentant un premier fluide comportant un fluide de dioxyde de carbone écumé, un émulsion de dioxyde de carbone ou un gel de dioxyde de carbone et un second fluide comportant un fluide alcalin réticulé.
