Abstract

There is disclosed an expandable seal assembly for a downhole tool, such as a downhole packer, and a downhole tool incorporating the expandable seal assembly. An exemplary expandable seal assembly (12) comprises an elastically deformable primary component (28) of a first material, and a seal component (30) of a second material having a modulus of elasticity which is less than that of the first material. The primary component is at least partially encased within the seal component. In use, the seal assembly is radially expandable between an unexpanded configuration where the seal component is out of contact with a downhole surface (22), and an expanded configuration where the seal component sealingly abuts the downhole surface. The seal assembly describes an inner diameter, the inner diameter (DE) of the seal assembly in the expanded configuration being greater than the inner diameter (Du) of the seal assembly in the unexpanded configuration.
