Abstract
A method of forming a downhole apparatus comprises the steps of providing a body having a longitudinal axis and forming an expanding portion on the body from multiple layers of a partially or substantially cured material around the longitudinal axis of the body. The material is selected to increase in volume on exposure to at least one predetermined fluid, such as a wellbore fluid. Apparatuses formed by the method include wellbore packers.
