ABSTRACT:
The invention describes the use of selected esters, fluid at room temperature and with flash points above 80.degree. C., from monocarboxylic acids of synthetic and/or natural origin with 6 to 11 carbon atoms and mono- and/or polyfunctional alcohols as the oil phase or a component of the oil phase of invert drilling muds, which are suitable for environment-friendly development of petroleum and natural gas deposits and in a continuous oil phase contain a dispersed aqueous phase together with emulsifiers, weighting agents, fluid-loss additives and preferably further conventional additives. In a further embodiment the invention relates to invert-drilling fluids of the types mentioned, which are characterized in that the oil phase contains esters of monocarboxylic acids of synthetic and/or natural origin with 6 to 11 carbon atoms and with mono- and/or polyfunctional alcohols preferably in admixture with other components from the class of ecologically acceptable compounds.
