..., a combination of oil-in-water (O/W) and water-in-oil (W/O) emulsions will form in the water channels, effectively blocking them off. Further injected solution will therefore contact fresh regions of the core. It is shown that this design of AS injection in heavy oil leads to improved sweep efficiency...

... commercial electrocoalescence processes have a low efficiency for Extra Heavy Oils because of the presence of polar heavy components limiting the electrocalescence effect and consequently limiting the efficiency of electrostatic coalescer. The objective is to determine the most efficient electrocoalescence...

... Abstract Bitumen extraction efficiency is increased in oil sands ore-water slurry based extraction process by increasing solubility of naturally occurred asphaltic acids by addition of CaO (lime) and/or by oxidation of bitumen asphaltenes by Ozone ( O 3 ) to surfactant species, at as low...

The results show that injecting high temperature steam into reservoir can not only reduce the viscosity of waxy oil, but also lead to the thermal expansion of the underground fluid and the distillation of the crude oil. The combining effect can improve sweep efficiency and enhance...

... on the viscosity reduction efficiency. In particular we show that the addition of a polar solvent to a solution of asphaltenes in toluene acts on the colloidal structure of the asphaltenes. The relative viscosity of the solution decreases, as well as the size of the aggregates of asphaltenes. In the same way...
