Abstract
Effect of surfactant and extra-light crude oil addition on the rheological
behaviors of an Algeria crude oil in order to improving its flowability were
studied at low temperature. These rheological properties include steady
flow behavior, yield stress and viscoelastic behavior. An AR-2000 rheometer
was employed in all of the rheological examination tests. Results show
that Toluene and extra-light crude oil addition causes a strong reduction
in viscosity, the yield stress and can effectively increase of crude oil transport
capacity. The toluene addition gets its best flow capacity and lowest
viscosity at 6%. The extra-light crude oil addition obtains its best flow capacity
and lowest viscosity at 50%. The viscoelasticity character of the crude
oil has indicate a significantly influence by the addition of Toluene and
extra-light crude oil.
