Renown’s Model ‘HDO-2’ Liner Packer is an extremely rugged hydraulic set liner top.  Like the standard ‘HDO’ with the addition of having a secondary internal piston duplicating piston force for pack-off and allowing smaller running diameters.  This system is often run in tandem with the ‘RIP’ plug to utilize a single trip isolation system to complete a well.  The large piston area compresses both individual elements creating a tandem seal.  This allows a significantly stronger seal area with maximum pack off force making it a superior horizontal liner packer.

Third party thermal testing has been completed to prove a capable pressure test when scrubbing up and down the casing walls due to thermal expansion and contraction in environments over 330°C (626°F).
