Abstract
A liquid-solid compositional model that uses an equation of state has been developed to predict the phenomenon of wax deposition in model oil wells. N umerical solutions to the conservation equations for Newtonian-to.-non-Newt onian flow regimes show temperature, radial mass flux and wax deposition pr ofiles as a function of time and position in the pipe, using realistic pres sure and temperature profiles of a model well. Such rheologic regime change s are dictated by thermodynamic arguments.
