Eccentric Annulus Effects

Eccentric Annulus Effects is a fluid dynamics phenomenon in wellbore hydraulics characterized by the non-uniform distribution of drilling fluid velocity and pressure gradients in the annular space between the drillstring and borehole wall caused by axial misalignment of the drillstring, leading to asymmetric cuttings transport and potential hole cleaning inefficiencies.
