A method of determining dilution of a well bore fluid, such as a drilling fluid, comprising preparing a drilling fluid having a known concentration of bromide ion, using the drilling fluid, recovering a sample of the used drilling fluid, determining quantitatively the concentration of bromide ion in the used drilling fluid, comparing the concentration of bromide ion in the sample drilling fluid with the known concentration of bromide ion in the drilling fluid and determining the dilution of the drilling fluid. |
