CaCO 3 scaling tendency can differ over seawater flood life

Seawater can reduce the likelihood of scaling caused by a formation brine that has a high calcium carbonate (CaCO 3 ) scaling potential. Seawater is often injected into reservoirs for pressure maintenance and enhancing oil recovery. Commingled with formation brine, the seawater lessens the CaCO 3 scaling potential of the mixture. As the percentage of seawater in the mixture increases, scaling potential decreases and may even become negative. Once the scaling potential becomes negative, the
