SYSTEMS AND METHODS FOR TREATING A SUBTERRANEAN FORMATION USING CARBON DIOXIDE AND A CROSSLINKED FRACTURING FLUID

摘要

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.
