Wax precipitate is one of the most serious issues the oil industry is currently facing, since it can cause some troubles such as increasing of the pressure losses in pipe which subsequently increases the required power for pumpage. To remove this problem, prediction of wax disappearance temperature (WDT) seems necessary. In this study, the pressure influence on the wax disappearance temperatu...

Self-consistent dynamics of the multi-component, N -field quintessence and gravity is formulated as relativistic N -body dynamics, embedded in a static viscous flat space and under the forces given by the interacting Lorentz scalar potential via exchanges of field bosons. The Ratra-Peebles power-law potential of effective single-field quintessence can be derived from this ”microscopic” perspect...
