摘要
A biodegradable additive concentrate having a pour point in accordance with the ASTM D97 standard lower than -5°C, improving the lubricity of aqueous sludges, comprising at least one compound chosen from the group consisting of mono- and diesters of diglycerol; acids and ester derivatives of monocarboxylic fatty acids comprising between 16 and 22 carbon atoms per chain; acids and ester derivatives of resin acids; polyol monoesters comprising more than 4 hydroxylated groups and carboxylic fatty acids comprising between 6 and 12 saturated and unsaturated carbon atoms with an unsaturation number of at least 1; mono- and polyalkoxylated esters of saturated and unsaturated dicarboxylic acids comprising between 6 and 12 carbon atoms. The use of this concentrate in an aqueous sludge and the aqueous sludge comprising said concentrate that can be used for drilling.
