    • 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.

    • In a first embodiment, the invention relates to the use of basic amine compounds of pronounced oleophilic character and at most limited solubility in water, which are capable of forming salts with carboxylic acids, as an additive for w/o invert drilling muds which contain in the continuous oil phase ester oils and, together with the disperse aqueous phase, emulsifiers, weighting agents, fluid loss additives and, if desired, other additives for protecting the drilling muds against unwanted thickening in use or for improving their flowability. In another embodiment, the invention relates to w/o invert drilling muds which are suitable for the improved offshore development of oil and gas sources and which are characterized by the presence of basic amine compounds of pronounced oleophilic character which are capable of forming salts with carboxylic acids.
