For each run, the reservoir cell is designed to be 200 gm of which 18 gm brine water, 42 gm heavy crude oil and 140 gm fine sand grains [ Fig. 8 ]. Environmental Analysis The main...

... the experiments suggest that aggregation of the small-sized biodiesel droplets of SBDWE (~1μm) at the interface between heavy oil and SBDWE can form a stable emulsion phase. Creaming of SBDWE is a poor emulsification indication and can be avoided by controlling experimental variables such as injected volume...

.... Experimental Setup Glass-based capillary tubes with diameter of 1.02 mm were utilized to examine the interactions between two miscible fluids, i.e., solvent and viscous oil. A camera (Canon EOS 7D) was used to record the physical processes during the experiments. Oil-based fluorescer was employed to dye...
