ABSTRACT:
New drilling fluids have been invented which are invert emulsion fluids comprising an oleaginous liquid, a non-oleaginous liquid, and a protonated amine. Such fluids are acidic and thus useful in drilling wells in which acidic gases such as CO.sub.2 or H.sub.2 S are likely to be encountered and break, i.e. de-emulsify, the drilling fluid.
