New drilling fluids have been invented which are invert emulsion fluids comprisng an aleaginous liquid, a non-oleaginous liquid, and a protonated amine. Such fluids are acidic and thus useful in drilling wells in which acidic gas es such as CO2 or H2S are likely to be encountered and break, i.e. de-emulsify, the drilling fluid.
