ABSTRACT:
A high density brine useful as a drilling fluid for deep wells is rendered corrosion resistant by the incorporation of a soluble aliphatic or aromatic aldehyde with or without olefinic unsaturation and with the use of alkali metal thiocyanates or ammonium thiocyanates. The aldehyde can be reacted with a primary amine prior to use.
