ABSTRACT WELL PACKER An inflatable well packer includes several annular layers 1,3,5,7 of material, consisting of a series of oriented fibres 27 encapsulated in an elastomeric resin. The inner and outer circumferential surfaces of the well packer each carry a protective layer 9,11 of material effective to protect the elastomeric resin. Each layer 9,11 is deposited on the well packer in a folded configuration, such that unfolding of the layers enables inflation of the well packer. A method of making the well packer, using a moulding technique is also described. Figure 1 to accompany abstract
