Modelling of Fluid Flow and Cuttings Transport in Horizontal Narrow Annulus

The motivation for this research originated from the little understanding on the phenomenon of cuttings and liquid flow in narrow horizontal wellbore. The study was aimed at modelling single-phase yield power law (YPL) fluid flow and two-phase (cuttings-water, cuttings-power law, and cuttings-YPL...
