    • 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

    • The invention relates to flowable and pumpable multicomponent mixtures based on a multiphase mixture of water and oil containing emulsifiers and, if desired, other soluble, emulsifiable and/or dispersible auxiliaries for their use in exploration by drilling and/or for the further treatment of the wells thus drilled. The invention is characterized by the use of emulsifiers or emulsifier systems which, in the particular multicomponent mixture in question, lead to temperature-controlled phase inversion at a phase inversion temperature (PIT) in a temperature range of which the upper limit is so far below the working temperature of the multicomponent mixture in geological exploration that the water-based part of the multicomponent mixture is present as a disperse (invert) phase in the continuous oil phase (w/o invert emulsion) while the lower limit of this temperature range enables the multicomponent mixture to be converted into an o/w emulsion with a continuous aqueous phase. At least partly nonionic emulsifiers or emulsifier systems with a PIT of 0 to 100.degree. C. are particularly suitable. The invention enables the requirements in regard to technical performance, ecological compatibility and cost/effectiveness ratio to be optimally satisfied.

    • The invention describes the use of water-insoluble esters with flash points above 80.degree. C., from monohydric alcohols of natural and/or synthetic origin with at least 4 carbon atoms, preferably at least 6 carbon atoms in the alcohol radicals, as the oil phase, or a constituent of the oil phase of invert drilling fluids which exist as W/O-emulsions, have a dispersed aqueous phase and ideally also have further usual additives in the continuous oil phase, which is fluid and pumpable in the temperature range of 0.degree. to 5.degree. C., and which are suitable for the environment-friendly development of, e.g., petroleum and natural gas deposits. Drilling fluids of the above type are also described which are characterized in that they contain as the continuous oil phase, or dissolved in ecologically-acceptable water-insoluble oils, an additive of at least largely water-insoluble ethers from monohydric alcohols, the oil phase in each case being fluid and pumpable in the temperature range of 0.degree. to 5.degree. C. and having flash points above 80.degree. C.
