Drill String Eccentricity

Drill String Eccentricity is a mechanistic parameter in drilling engineering that characterizes the radial displacement of the drill string axis from the wellbore axis within an annular flow domain, distinguishing it from concentric configurations by quantifying the asymmetry in fluid and solid interactions during hole cleaning.
