Abstract
A metal ring seal capable of providing a fluid seal between two downhole assemblies. The ring seal has a 'C' shape, is initially located inside one of the downhole assemblies adjacent to an internal wedged section of that assembly and has an inner diameter that is at least as large as the outer diameter of the second downhole assembly. When the ring seal is moved along the internal wedged section into a sealing position, the two ends of the 'C' shape sealingly contact each other and the inner diameter of the ring is smaller than the outer diameter of the second assembly so as to create a seal between the first and second assemblies.
