Abstract: We derive a selection of energy estimates for a generalisation of a critical equation on the unit disc in $ \mathbb{R}^2$ introduced by Rivière. Applications include sharp regularity results and compactness theorems which generalise a large amount of previous geometric PDE theory, including some of the theory of harmonic and almost-harmonic maps from surfaces.
