摘要
Use of selected esters of monofunctional alcohols with 2 to 12, in particular 4 to 12, C atoms and aliphatically saturated monocarboxylic acids with 12 to 16 C atoms, which are fluid and pumpable in the temperature range of 0 to 5 DEG C, as the oil phase of invert drilling sludges, suitable for non-polluting exploitation of off-shore petroleum or natural gas deposits, and containing, in a closed oil phase, a disperse aqueous phase together with emulsifiers, loading agents, fluid-loss additives and, if necessary, other usual additives.
