The data were used to adapt two commonly used compositional viscosity models, Pedersen's and Lohrenz, Bray and Clark (LBC), such that these models can be used for black-oil systems when compositional data are missing. The oil viscosity ranged from 0.13 to 78.3 cP, with pressure from 14.7 ...

One of the main challenges associated with the production of heavy or extra-heavy crude oil is transportation of the oil by pipelines, particularly without the prior reduction of the oil viscosity to acceptable values to ensure oil fluidity in the pipelines. The reduction of viscosity can be obta...
Flooding displacements carried out through the sandpack model using nanofluids and Egyptian crude oil of 30.7 API that was extracted from the Western Desert. After conventional brine flooding, the crude oil viscosity was measured to be 6.429 cp. While viscosity of the same crude oil was found to...
with water cut in process of water drive on dynamic displacement characteristics, classical non piston displacement theory is improved by considering the increase of crude oil viscosity, and a one dimensional mathematical model for oil/water two phase percolation flow through porous media is established...

The procedure of Example 1 is repeated except the asphaltene containing hydrocarbon is a Venezuelan crude oil having a viscosity of about 8300 cP at 140° F., the dispersants defined in FIG. 3 are studied. The "effective" LLV results are plotted in FIG. 3 and show a critical polarity rang...
A method is described for recovering viscous oil having a viscosity above 50 cp by means of thermal energy, wherein fluids are applied which have the property to decrease the viscosity of the oil independent of the temperature of the applied fluid. There is simultaneously injected into the ...
Solutions to address the operational problems of asphaltenes must address both problems of asphaltenes precipitation. And these solutions must improve the crude oil specifications including raising API gravity and decreasing crude oil viscosity. The API gravity and viscosity impact the price of crude oil...
