Abstract

The invention relates to a dynamic annular sealing apparatus comprising a resilient sleeve deformable between a closed sealing configuration and an open non-sealing configuration and a pump controllable to effect such deformation by alteration of pressure exerted on the sleeve. The apparatus is particularly suited to use in wellbore applications.
