Evolving steam cycle phenomena that affect oil-wetting and the nature of produced emulsions including specific gravity.
Flow regimes and oil/water ratios.
Water chemistry as effected by dissolved solids, acid gases, oxygen ingress and the presence of low molecular weight organic acids.
Thermodynamic considerations based on pH and electrochemical oxidation-reduction potential (ORP) as diagramed in Pourbaix format.
Effects of temperature and pressure changes.
The effect of accumulated solids.
Contamination and temperature lowering by injecting surface water and/or trucked in fluids into the emulsion lines.
Effects of injecting oxygen laden vapor recovery unit (VRU) liquids into the emulsion lines.
