Application of the HLD Value in the Petroleum Industry

Abstract

The efficiency of demulsification is a key process in terms of extracting the oil of O/V (oil-in-water type) emulsions of enhanced oil recovery. Consequently, the separation of emulsion systems and the recovery of the maximum amount of oil from the colloid system play an important role in the petroleum industry. The stability of the emulsions from oil recovery is influenced by numerous factors. J. L. Salager developed the HLD (Hydrophilic-Lipophilic Deviation) equation in order to examine the efficiency of demulsification. Our aim was to investigate whether the equation developed by Salager is suitable for monitoring the stability of petroleum industrial emulsions.
