Abstract: The present invention provides a method of deploying a eutectic alloy based tool within an oil/gas well. The method comprising providing a eutectic alloy based downhole tool comprising a tubular body with eutectic alloy located on an outer surface thereof, said tool having an outer diameter with a clearance from the inner diameter of the well. The downhole tool is delivered to a target region within an oil/gas well where the tool is to be deployed. Once the tool is in position within the well a tubular expanding tool is run through the interior of the tubular body so as to increase the outer diameter of the sealing downhole tool and in so doing reduce the clearance between the alloy and the well. Following the expansion of the tubular body a heater is deployed within the tubular body proximal to the alloy and operated to melt the alloy. The alloy is then allowed to cool and resolidfy, whereby the tool is sealed in place within the target region of the well using the alloy.

Abstract: Downhole tools and methods, of which the downhole tool includes an expandable sleeve defining a bore therethrough, and a first body positioned at least partially within the bore of the expandable sleeve. The first body is slidable relative to the expandable sleeve, and sliding the first body along the bore of the expandable sleeve causes the expandable sleeve to radially expand so as to actuate the downhole tool from a run-in configuration to a set configuration. The downhole tool also includes an isolation device received at least partially in the expandable sleeve in the set configuration. A pressure on the isolation device is at least partially transmitted to the expandable sleeve as a radially-outward force.

Abstract: A method of expanding a tubular member by assembling an expansion system having an expansion cone and an expansion sleeve and coupling a tubular member to the expansion system so that the expansion sleeve is at least partially disposed within the tubular member. The expansion system and tubular member are then disposed in a wellbore and the expansion cone is translated relative to the expansion sleeve and tubular member so as to radially expand the tubular member into engagement with the wellbore and the expansion system is removed from the wellbore. The tubular member is expanded to an inside diameter equal to an expansion diameter of the expansion cone plus twice a thickness of the expansion sleeve.

Abstract: A liner installation system for use in a wellbore having a casing string disposed therein. The system includes a liner string having a liner hanger and a liner top and a setting tool having an expansion cone assembly and a locator cylinder. After running the liner string through the casing string such that at least the liner hanger is positioned within the wellbore casing, the setting tool is run through the casing string until the locator cylinder contacts the liner top. Thereafter, axially moving the expansion cone assembly through the liner string radially expands the liner hanger into contact with the casing string.
