Influence of surfactants used in surfactant-polymer flooding on the stability of Gudong crude oil emulsion

The stability of water-in-oil emulsion of some Malaysian crude oils was studied with particular emphasis on effect of interfacial active components existed in the crude oil, i.e. asphaltene, resin and wax. The emulsion stability was studied by measuring the volume of water or oil phase separated in variation with time, water hold up, and the heights of the sedimenting/coalescing interfaces during the separation at various temperatures. The study investigated the influence of asphaltene, resin and wax on emultion stability if it`s present in the crude oil alone, together or combination one of the others. The result show that the interfacial active component that stabilize emulsion is asphaltene. The resin and wax do not form stale emulsion either aloneor together. There is a correlation between emulsion stability and physicochemical properties of crude oil which showed that higher asphaltene content in the crude oil would form more stable emultion. Increased temperature was found to cause instability of emultion. Keywords : emultion stability, crude oil, asphaltene, resin and wax

Abstract: The Polymer is one of the efficient ways to increase to the crude oil production rate,but this method has big impact on the properties of crude oil. We studied the differences between the Polymer flooding sample and H2O flooding sample experimentally.The adsorption method was adopted to analyze the content of resins and asphaltenes in the oil samples. By measuring the exhalation rate of the H2O, the stability of the emulsifying properties which are affected by the resins and asphaltenes were studied. Then, we measured the viscosity and the interfacial tension of the crude oil samples to further explore the differences.The results shows that the contents of resins and asphaltenes and the stability of the emulsion in the Polymer flooding oil sample are all higher than that in the H2O flooding oil sample, the interfacial tension and the viscosity of the produced water in the Polymer flooding oil sample are all lower than that in the H2O flooding oil sample.

The purpose of this research is to look into the formulation and evaluation of concentrated water-in-oil (W/O) emulsions stabilized by UMP NS-19-02 surfactant and their application for crude oil emulsion stabilization using gummy Malaysian crude oil. A two-petroleum oil from Malaysia oil refinery, i.e., Tapis petroleum oil and Tapis- Mesilla blend, were utilized to make water-in-oil emulsions. The various factors influencing emulsion characteristics and stability were evaluated. It was discovered that the stability of the water-in-oil emulsion improved by UMP NS-19-02 improved as the surfactant content rises, resulting in the decline of the crude oil-water interfacial tension (IFT). Nevertheless, the most optimum formulation of W/O emulsion was a 50:50 W/O ratio with 1.0% surfactant. Additionally, raising the oil content, salt concentration, duration and mixing speed, and pH of the emulsion resulted in higher emulsion stability. It also raised the temperature of the initial mixing, which significantly decreased the formulated emulsions' viscosity. The results showed that stable emulsions could be formed using the UMP NS-19-02 surfactant.

Characterization of rheological behavior of alkali-surfactant-polymer (ASP) solution and oil emulsion is difficult, due to the complex chemical components and various physiochemical reactions with oil during chemical flooding. Through rheological experiments of ASP and crude oil emulsion, this paper presents the studies on influencing factors of rheological behavior, including interfacial tension, polymer and water cut, and discusses the stability mechanism of ASP and crude oil emulsion. The relationships among viscosity, interfacial tension, water cut and sheer rate were built through fitting the experimental data. The model and calculation can be used to more accurately simulate the ASP flooding in oil reservoirs.
