%X Naphthenates soaps emulsion generated from alkaline (A), surfactant (S) and polymer (P) flooding were studied with crude oil contained amphiphilic carboxylic acids, RCOOH from Malaysian oilfield. These naphthenic acids were characterised using high-resolution fourier transform ion-cyclotron resonance mass spectroscopy (FTCIR-MS). Alkaline Na 2 CO 3 resulted in increase in pH of produced water to between pH 9 to 11 and generates in-situ oil-rich colloidal dispersion ultralow interfacial tension (IFT) character of sodium carboxylate soaps emulsion. Predictive measurement and inhibition were evaluated using new naphthenate inhibitor (NI)- demulsifier synthesized from fatty hydrazide. The structures of the synthesized compounds have been established by FTIR, 1 H NMR, 13 C NMR, and mass spectrometry (LCMS/MS). Inhibition and demulsification properties have been evaluated at operating parameters such as produce water cut level, ASP concentration and temperatures under dynamic testing condition using Multifunctional Mini Flow Loop (MMFL TM ). © Published under licence by IOP Publishing Ltd.
