Experimental study on the performance of emulsions produced during ASP flooding

Abstract ASP (Alkaline/Surfactant/Polymer) flooding is one of the most promising techniques that has proven to have successful application in several laboratory and pilot tests. However, formation persistent stable emulsions associated problems with flooding. The present work investigated effect sodium carbonate alkaline, Alpha Olefin Sulfonate (AOS) surfactant, GLP100 polymer on produced crude oil emulsion. study was conducted by measuring emulsion stability terms water separation rag layer volume using a TurbiScan analyzer, dispersed droplet size cross-polarization microscopy, interfacial tension spinning drop tensiometer, rheological properties rheometer. experimental results shown AOS presence increased only when its concentration above 100 ppm. Meanwhile, below ppm, promoted reduced volume. In less significant manner, high alkali use Polymer substantial ability promoting reducing minimal level. It believed outcomes this will aid developing suitable destabilization process enhance oil–water treatment from production fields. Further investigations AS, AP, SP as well ASP's combined stability, size, are highly recommended support decision-makers EOR implementations chemical additives.
