Aqueous swellable compositions of guar gum and guar gum derivatives in oleophilic liquids and their use |
摘要 |
The invention relates to the use of oil-soluble oleophilic organic liquid phases-flowable at temperatures of 0 to 10° C.-from the classes of corresponding monocarboxylic and/or polycarboxylic acid esters, carbonic acid esters, fatty alcohols and their oligoalkoxides and/or ethers as the at least predominant part of the liquid phase in storage-stable homogeneous mixtures with guar and/or water-soluble guar derivatives for their use in water-based borehole servicing fluids.
