Produced water oil to the production wells. The injected water eventually reaches the production wells, and so in the later stages of waterflooding, the produced water proportion ("cut") of the total production increases. The water composition ranges widely from well to well and even over the life of the same well. Much produced water is brine, and most formations result in total dissolved solids too high for beneficial reuse. All produced water contains oil and suspended solids. Some produced water contains heavy metals and traces of naturally occurring radioactive material (NORM), which over time deposits radioactive scale in the piping at the
