Lubricant additives for drilling fluids |
| abstract |
A description is given of the use of oligoglycerol fatty acid ester, prepared from (a) an acid component selected from (a1) fatty acids of the general formula (I) in which R is a saturated or unsaturated, branched or linear alkyl or alkenyl radical having 7 to 21 C 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 selected from oligoglycerols or alkoxylates of oligoglycerols, as an additive to oil-based drilling fluids for the purpose of enhancing the lubricity of these drilling-mud systems. |
