Figure 3. Bromide/chloride versus chloride concentration for ground waters in the study area and oil brines east of the study area. The solid curves represent the mixing of freshwater or slightly saline water with oil brine. The dashed curves represent the mixing of freshwater with halite-dissolution brine. Each pair of curves encloses a zone of mixing.

Oil-field samples have high chloride concentrations; others are less than 5000 mg/l, but bromide/chloride mass ratio is similar for some wels to those of oil-field brines.
