Abstract:
The use is described of oligoglycerol fatty acid esters, produced from (a) an acid component, selected from (a1) fatty acids of the general formula (I) R—COOH (I) in which R stands for a saturated or unsaturated, branched or linear alkyl- or alkenyl radical with 7 to 21C atoms, and/or (a2) dicarboxylic acids and/or (a3) dimer fatty acids and/or (a4) oligomer fatty acids and/or (a5) hydroxy fatty acids with (b) a polyol component, which is selected from oligoglycerols or alkoxylates of oligoglycerols, as additive to oil-based drilling mud compositions to improve the lubricating effect of these mud systems.
