Influence of asphalt-tar matter washing-out on viscosity of displaced oil
Analyzed are the results of lab experiments on displacement of oil, containing asphalt-tar matter, by water and surfactant solutions. Accomplished are calculations of viscosity ratios for oil, displaced by water and surfactant solutions, based on the assumption of greater desorption of asphalt-tar matter by surfactant solutions.
