Abstract

A universal backup member is provided for use on packers and other downhole tools that use members selected for expansion upon exposure to a wellbore fluid. The backup member prevents axial extrusion of the swellable member. An elastomer portion of the backup member is selected for expansion in wellbore fluids that include both aqueous solutions and hydrocarbons, without regard to the fluid in the wellbore.
