Produced water management should be done to avoid problems with the environment. The produced water is either injected into a disposal well or injected into a producing formation for enhanced oil recovery .This study carried out in Adar-Yale oilfields. One water sample collected from field processing facilities in d Adar-Yale and One water sample collected from formation water in the same field .The water sample for every field (formation and produced water blend together). Nineteen blends of these waters tests for anions using UV Spectroscopy and cations using Inductive Coupled Plasma –optical Emission Plasma (ICP-OES).Scale deposition calculated for every blend and select the best blend to use for injection.
