ABSTRACT:
A well treatment fluid comprising a mixture of (A) a major amount of a first hydrocarbon fluid, the first hydrocarbon fluid being composed predominantly of diaromatics and triaromatics having more than 16 carbon atoms, and (B) a minor amount of a second hydrocarbon fluid, the second hydrocarbon fluid being composed predominantly of hydrocarbons having from 7 to 12 carbon atoms. The mixture preferably has a density greater than 1000 kg/m.sup.3 at 15.degree. C. and a viscosity lower than 30 centiStokes at 20.degree. C. In a method according to the invention, a kill fluid is formed by mixing the first and second hydrocarbon fluids to produce a hydrocarbon mixture, preferably having a viscosity of less than 30 centiStokes at 20.degree. C. and a density above 1000 kg/m.sup.3 at 15.degree. C.
