Abstract
Disclosed is a method of preparing an inflatable packer including a mandrel and a sleeve for insertion into a fluid filled well bore. The method includes pressure testing the sleeve and its connection with the mandrel with a gas without introducing any incompressible fluid between the area of contact between the sleeve and mandrel. The method also includes the filling any pressure vulnerable areas in the packer not in the area of contact of the sleeve and mandrel with an incompressible fluid.
