We focus on a mostly non-wetting regime, given by the condition $\\theta_{\\rm e} - \\beta > 90^\\circ$, where the droplet forms a liquid barrel -- a closed shape of positive mean curvature. Using a quasi-equilibrium assumption for the shape of the liquid-gas interface, we compute the surface energy landscapes experienced by the liquid upon translations along the symmetry plane of the wedge.
