Emulsion Characterization of the Heavy Oil-Alkaline Water System in Alkaline Flooding Mechanism Investigation Using a Combination of Modified Bottle Test and Sandpack Flooding

Due to the diversity of alkali categories and reservoir conditions, varied oil recovery driving mechanism alkaline flooding is subjected different types emulsion generation. In this study, a modified bottle test method that assesses major type formation for preliminary prediction performance in introduced. The considers necessary energy input required mixing immiscible bulk phases at low interfacial tension (IFT) regions improve representativity porous media. To accurately evaluate phase volume distribution from test, each after aging was sampled its water content measured through Karl Fischer titration. Afterward, material balance calculations other than pure observation were applied quantify determine formation. It found majority effluent sandpack agreement with forecast which proved feasibility method. statistically optimized experimental designs implemented due simplicity new it considerably cut time expense regarding prediction. high versatility ensures usage not limited inorganic alkalis mentioned study; solutions can also be used further expanding scope application.
