In this note, we present some results concerning the gas displacement of power-law liquids and viscoplastic Papanastasiou's materials improving the understanding of the problem considered in Sousa et al. ( 2007) [1]. Specifically, we present: the fraction of mass attached to the wall for a viscosity
