    • The invention relates to a process for facilitating the disposal of flowable and pumpable working fluids based on emulsifiers containing W/O invert emulsions--more particularly corresponding auxiliaries of the type used in geological exploration, such as oil-based w/o invert drilling muds--and for the simplified cleaning of solid surfaces soiled therewith, if desired using flowable spraying aids, the process being characterized in that, by selecting and adapting the emulsifiers/emulsifier systems to the oil phase of the invert emulsion, temperature-controlled phase inversion is achieved at temperatures below the in-use temperatures of the w/o invert emulsions, but above the freezing point of the aqueous phase and in that disposal and cleaning are carried out at temperatures in and/or below the phase inversion temperature range. The invention also relates to the use of this process for the cleaning and disposal of roc cuttings covered with residual drilling mud from geological exploration during and/or preferably before their on-shore or off-shore dumping

    • Described is the use of oleophilic esters of ecologically compatible polycarboxylic acids with oil-soluble and ecologically compatible monofunctional alcohols and/or polyfunctional alcohols which may also be watersoluble as the oil phase or as a component of the oil phase of oil-based or water-based drilling fluids and other fluid drill-hole treatment agents. The oleophilic polycarboxylic acid esters are especially suitable as component of the continuous oil phase of inverted fluids of the W/O type. Here--if rheologically suitable compounds will be employed--they may comprise the at least predominant portion of the continuous oil phase; but also possible is the concomitant use of complex oleophilic polycarboxylic acid esters, which are not or just to a restricted degree fluid in a temperature range of from 0.degree. C. to 20.degree. C., as an additive in fluid oils of the class of the non-polluting oils. Here, suitable oil mixing phases especially are oleophilic alcohols, ethers, respective esters of monocarboxylic acids and fluid oils based on oleophilic carbonic acid diesters.
