Abstract
A hydraulic fluid delivery tool for morphing a tubular downhole and a method of morphing a tubular downhole. The tool has spaced apart annular elastomer seal assemblies which operate by application of a piston against each elastomer to create a seal against the tubular. A first hydraulic fluid delivery line delivers fluid at a first pressure to operate the pistons. A second hydraulic fluid delivery line delivers fluid at a second pressure, lower than the first, to a location between the seals to morph the tubular and act on a second face of each piston to assist in maintaining the seal.
